You can split the window into multiple panes successfully, great!
As you can see, each argument of xpanes is re-assigned to echo's argument.
Next, let's close those panes.
Don't worry if you are not familiar with key bindings of tmux.
Just type exit and "Enter" key to close the panes.
+-------------------------------+-------------------------------+
│$ exit │$ exit │
│ │ │

+-------------------------------+-------------------------------+
As shown above, input from keyboard is synchronized within multiple panes by default.
To disable the synchronization of keyboard input within panes, use -d (or --desync) option. The input is applied to only one of them. Set tmux synchronized-pane on to re-enable synchronization.
$ xpanes -d 1 2 3 4
-c option is one of the fundamental options of xpanes.
Its argument is used as a command to be executed.
For example, try this one.
$ xpanes -c 'seq {}' 1 2 3 4You will get the screen like this.
+-------------------------------+-------------------------------+
│$ seq 1 │$ seq 2 │
│1 │1 │
│ │2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
│$ seq 3 │$ seq 4 │
│1 │1 │
│2 │2 │
│3 │3 │
│ │4 │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
seq command which generates sequential numbers is specified by -c.
As you can see, {} is replaced each arguments. This placeholder can be changed by -I option like this.
$ xpanes -I@ -c 'seq @' 1 2 3 4echo {} is used as the default placeholder when no command is specified by -c option.
Brace expansion provided by Bash or Zsh is very useful to generate sequential numbers or alphabetical characters.
# Same as $ xpanes 1 2 3 4
$ xpanes {1..4}It is good to know about the conditional behavior of xpanes before checking further usages.
When the tmux is not open and xpanes is executed on the normal terminal, the xpanes's behavior is as follows:
- It newly creates a tmux session and new window on the session.
- In addition, it separates the window into multiple panes.
- Finally, the session will be attached.
When the tmux is already open and xpanes is executed on the existing tmux session, the command's behavior is as follows:
- It newly creates a window on the existing active session.
- In addition, it separates the window into multiple panes.
- Finally, the window will be active.
When xpanes accepts standard input (i.e, xpanes follows another command and pipe |) under Normal mode2 , xpanes's behavior is going to be the special one called "Pipe mode".
It is documented in the Pipe mode section.
$ xpanes -c "tail -f {}" /var/log/apache/{error,access}.log /var/log/application/{error,access}.logThe result is like this.
+------------------------------------------+------------------------------------------+
│$ tail -f /var/log/apache/error.log │$ tail -f /var/log/apache/access.log │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------------------+------------------------------------------+
│$ tail -f /var/log/application/error.log │$ tail -f /var/log/application/access.log │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------------------+------------------------------------------+
Hmm? Do you want to monitor those files through the SSH? Just do it.
# 'ssh user@host' is added.
$ xpanes -c "ssh user@host tail -f {}" \
/var/log/apache/{error,access}.log \
/var/log/application/{error,access}.log$ xpanes -c "ssh myuser@{}" host1 host2 +-------------------------------+-------------------------------+
│$ ssh myuser@host1 │ $ ssh myuser@host2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
--ssh option is helpful to ignore the alert message from OpenSSH. It is not required to answer yes/no question against it. Use it if you are fully sure that the connection is reliable one.
$ xpanes --ssh myuser1@host1 myuser2@host2This is same as below.
$ xpanes -t -s -c "ssh -o StrictHostKeyChecking=no {}" myuser1@host1 myuser2@host2
-t and -s options are introduced later.
$ xpanes --log=~/operation_log -c "ssh {}" user1@host1 user2@host2The result is like this.
+-------------------------------+-------------------------------+
│$ ssh user1@host1 │ $ ssh user2@host2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
In addition, log files will be created.
$ ls ~/operation_log/
[email protected]_21-30-07
[email protected]_21-30-07
File name format for log file can be specified with --log-format option.
Please refer to FORMAT for more information.
Attention: Logging feature does not work properly with particular tmux versions. Please refer to wiki > Known Bugs in further details.
$ xpanes -c "ssh -t {} bash -ci 'll'" host-{1,2,3}

-s option is useful if you have following issues.
- It takes long time to open the multiple new panes because default shell loads a bunch of configures (i.e
~/.zshrcloads something ). - If you do not want to leave commands on your shell history.
With -s option, xpanes does not create a new interactive shell.
Instead, a command is going to be executed as a direct child process of xpanes.
Here is the example.
$ xpanes -s -c "seq {}" 2 3 4 5As you can see, each pane starts from command's result, not shell's prompt like $ seq ....
+------------------------------------------+------------------------------------------+
│1 │1 │
│2 │2 │
│Pane is dead: Press [Enter] to exit... │3 │
│ │Pane is dead: Press [Enter] to exit... │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------------------+------------------------------------------+
│1 │1 │
│2 │2 │
│3 │3 │
│4 │4 │
│Pane is dead: Press [Enter] to exit... │5 │
│ │Pane is dead: Press [Enter] to exit... │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------------------+------------------------------------------+
Confirmation message like "Pane is dead..." is displayed when every process ends.
To suppress the message, use -ss instead of -s.
$ xpanes -t -c "ping {}" 192.168.1.{5..8}The result is like this.
As you notice, -t displays each argument on the each pane border.
It is called "pane title". The pane title is displayed with green background and black characters by default.
See Environment variables section to change the default format.
-x option creates extra panes to the window.
New window is not created then.
Here is the example xpanes is executed on the one of the three panes.
+-------------------------------+-------------------------------+
│$ │$ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
│ $ xpanes -x 4 5 6 │
│ │
│ │
│ │
│ │
│ │
│ │
│ │
+-------------------------------+-------------------------------+
Additional three panes are created.
+-------------------------------+-------------------------------+
│$ │$ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
│$ xpanes -x 4 5 6 │$ echo 4 │
│$ │4 │
│ │$ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
│$ echo 5 │$ echo 6 │
│5 │6 │
│$ │$ │
│ │ │
│ │ │
+-------------------------------+-------------------------------+
-e option executes given argument as it is.
$ xpanes -e "top" "vmstat 1" "watch -n 1 free"Then the result will be like this.
+-------------------------------+------------------------------+
│$ top │$ vmstat 1 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+------------------------------+
│$ watch -n 1 free │
│ │
│ │
│ │
│ │
│ │
│ │
+--------------------------------------------------------------+
You will get the same result with this command line.
$ xpanes -I@ -c "@" "top" "vmstat 1" "watch -n 1 free"-B option allows to run another command before processing -c option.
$ xpanes -B 'echo Preprocessing' -c 'echo Test' _ +-------------------------------+
│$ echo Preprocessing │
│Preprocessing │
│$ echo Test │
│Test │
│ │
│ │
│ │
+-------------------------------+
-B and -c are similar options.
However, -B can be used multiple times.
$ xpanes -B 'echo Pre1' -B 'echo Pre2' -B 'echo Pre3' -c 'echo {}' A B C D +-------------------------------+------------------------------+
│$ echo Pre1 │$ echo Pre1 │
│Pre1 │Pre1 │
│$ echo Pre2 │$ echo Pre2 │
│Pre2 │Pre2 │
│$ echo Pre3 │$ echo Pre3 │
│Pre3 │Pre3 │
│$ echo A │$ echo B │
+-------------------------------+------------------------------+
│$ echo Pre1 │$ echo Pre1 │
│Pre1 │Pre1 │
│$ echo Pre2 │$ echo Pre2 │
│Pre2 │Pre2 │
│$ echo Pre3 │$ echo Pre3 │
│Pre3 │Pre3 │
│$ echo C │$ echo D │
+-------------------------------+------------------------------+
It is helpful to customize default xpanes behavior with alias.
See Use alias.
-C and -R options are useful to change tha layout of panes.
A number of columns can be specified by -C (or --cols) option.
Here is the example that panes are organized in 2 columns.
$ xpanes -C 2 AAA BBB CCC DDD EEE FFF GGG HHH IIIThe result is like this.
+------------------------------+------------------------------+
│$ echo AAA │$ echo BBB │
│ │ │
│ │ │
+------------------------------+------------------------------+
│$ echo CCC │$ echo DDD │
│ │ │
│ │ │
+------------------------------+------------------------------+
│$ echo EEE │$ echo FFF │
│ │ │
│ │ │
+------------------------------+------------------------------+
│$ echo GGG │$ echo HHH │
│ │ │
│ │ │
+------------------------------+------------------------------+
As you may expect, -R (or --rows) option can fix the number of rows.
$ xpanes -R 5 AAA BBB CCC DDD EEE FFF GGG HHHPanes are organized in 5 rows.
+------------------------------+------------------------------+
│$ echo AAA │$ echo BBB │
│ │ │
+------------------------------+------------------------------+
│$ echo CCC │$ echo DDD │
│ │ │
+------------------------------+------------------------------+
│$ echo EEE │$ echo FFF │
│ │ │
+------------------------------+------------------------------+
│$ echo GGG │
│ │
+-------------------------------------------------------------+
│$ echo HHH │
│ │
+-------------------------------------------------------------+
Even if the number of arguments is not multiple of provided number, the number of panes on each row is adjusted to be as close as possible.
--bulk-cols accepts comma-separated numbers.
Each number is corresponding to the number of columns of each row.
$ xpanes --bulk-cols=1,3,1,2,5 {A..L}Here is the result.
+-------------------------------------------------------------+
│$ echo A │
│ │
+-------------------------------------------------------------+
│$ echo B │$ echo C │$ echo D │
│ │ │ │
+-------------------------------------------------------------+
│$ echo E │
│ │
+-------------------------------------------------------------+
│$ echo F │$ echo G │
│ │ │
+-------------------------------------------------------------+
│$ echo H │$ echo I │$ echo J │$ echo K │$ echo L │
│ │ │ │ │ │
+-------------------------------------------------------------+
The number of argument must equal to the sum of the comma-separated numbers.
In this example, the sum of the numbers of --bulk-cols is 12 (1 + 3 + 1 + 2 + 5 = 12) because there are 12 characters from A to L.
-l option is also useful to change the layout of panes.
For example, to line up panes vertically, put ev (it is corresponding to even-vertical in tmux manual) followed by -l.
$ xpanes -l ev -c "{}" "top" "vmstat 1" "watch -n 1 df"It would be like this.
+-------------------------------------------------------------+
│$ top │
│ │
│ │
│ │
│ │
+-------------------------------------------------------------+
│$ vmstat 1 │
│ │
│ │
│ │
│ │
+-------------------------------------------------------------+
│$ watch -n 1 df │
│ │
│ │
│ │
│ │
+-------------------------------------------------------------+
With same way, eh (even-horizontal), mv(main-vertical) and mh(main-horizontal) are available. Please refer to xpanes --help also.
Pipe mode is activated when xpanes command is accepting standard input.
With this mode, xpanes behaves like UNIX xargs.
# Pipe mode
$ seq 3 | xpanesWith this command line, the output would be like this.
+------------------------------+------------------------------+
│$ echo 1 │$ echo 2 │
│1 │2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------+------------------------------+
│$ echo 3 │
│3 │
│ │
│ │
│ │
│ │
│ │
│ │
+------------------------------+------------------------------+
Pipe mode has two features.
xpanes's argument will be the common command line which will be used within all panes (this is same as the-coption's argument in Normal mode).- Each line provided by standard input is corresponding to the each pane's command line (this is corresponding to normal argument of
xpanesin Normal mode).
# The command line generates some numbers.
$ seq 4
1
2
3
4
# Add those numbers to xpanes command.
$ seq 4 | xpanes seq
The result will be like this.
+-------------------------------+------------------------------+
│$ seq 1 │$ seq 2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+------------------------------+
│$ seq 3 │$ seq 4 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+------------------------------+
Off-course, -c and -I options are available.
$ seq 4 | xpanes -c 'seq {}'
## xpanes seq
## and
## xpanes -c 'seq {}'
## are same.However, giving both -c and any arguments causes error. Because the command cannot decide which argument should be used.
$ echo test | xpanes -c 'echo {}' echo
xpanes:Error: Both arguments and other options (like '-c', '-e') which updates <command> are given.
Pipe mode allows you to make combinations between tmux and other general UNIX commands.
For example, let's prepare ~/.ssh/config file like this.
Host host1
User user1
HostName 192.168.0.2
IdentityFile ~/.ssh/id_rsa
Host host2
User user2
HostName 192.168.0.3
IdentityFile ~/.ssh/id_rsa
Host host3
User user3
HostName 192.168.0.4
IdentityFile ~/.ssh/id_rsa
Parse host name with general UNIX commands.
$ cat ~/.ssh/config | awk '$1=="Host"{print $2}'
host1
host2
host3Giving the results to xpanes ssh command.
$ cat ~/.ssh/config | awk '$1=="Host"{print $2}' | xpanes sshThe results would be like this.
+------------------------------+------------------------------+
│$ ssh host1 │$ ssh host2 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+------------------------------+------------------------------+
│$ ssh host3 │
│ │
│ │
│ │
│ │
│ │
│ │
│ │
+------------------------------+------------------------------+
You may restore the tmux session created by xpanes even if it is unexpectedly disconnected from your terminal.
xpanes creates ~/.cache/xpanes/socket.<PID> file as socket file by default.
Try to find socket file like this.
$ ls ~/.cache/xpanes/socket.*
/home/user/.cache/xpanes/socket.1234If you find any socket files, try to attach it. The session might be recovered.
$ tmux -S /home/user/.cache/xpanes/socket.1234 attachYou can specify the socket file name with -S option.
Importing this socket file, different users can share their screens each other.
- user1
[user1@host] $ xpanes -S /home/user1/mysocket a b c d ...- user2
[user2@host] $ tmux -S /home/user1/mysocket attach... then, user1 and user2 can share their screen.
File name of log file generated by --log option can be changed by --log-format=FORMAT.
Default value of FORMAT is [:ARG:].log.%Y-%m-%d_%H-%M-%S.
Interpreted sequences are:
[:PID:]-- Process id of the tmux session[:ARG:]-- Argument name
In addition, sequences same as date(1) are available.
For example:
%Y-- year (e.g, 1960)%m-- month (e.g, 01)%d-- date (e.g, 31)
And etc.
Other sequences are also available.
Refer to date(1) manual.
As mentioned before, -B option is helpful to improve your xpanes with alias.
For example, define the alias like this.
Alias:
_tmp='INDEX=`tmux display -pt "${TMUX_PANE}" "#{pane_index}"`'
alias xpanes="xpanes -B '${_tmp}'"After that, execute this command.
$ xpanes -sc 'echo $INDEX' _ _ _ _ +-------------------------------+------------------------------+
│$ echo $INDEX │$ echo $INDEX │
│0 │1 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+------------------------------+
│$ echo $INDEX │$ echo $INDEX │
│2 │3 │
│ │ │
│ │ │
│ │ │
│ │ │
│ │ │
+-------------------------------+------------------------------+
As shown above, $INDEX has the index number of pane.
This technique is helpful to avoid that all the commands start simultaneously.
To wait each command start every second, just do it with the above alias.
$ xpanes -B 'sleep $INDEX' -c 'command {}' argA argB argC ...See wiki > Alias examples for more useful examples.
xpanes refers to following shell variables.
Add the statement to your default shell's
startup file file (i.e .bashrc, .zshrc) to change them as you like.
tmux-xpanes follows XDG Base Directory Specification.
XDG_CACHE_HOME is $HOME/.cache by default.
Therefore, $HOME/.cache/xpanes directory is used to store temporary data by default.
DEFAULT VALUE: tmux
It is preferentially used as a internal tmux command.
It is helpful if you want to use specific tmux version for xpanes, or enable specific options always.
Example:
export TMUX_XPANES_EXEC="/usr/local/bin/tmux1.8 -2"
# => xpanes command calls "/usr/local/bin/tmux1.8 -2" internally.DEFAULT VALUE: $HOME/.cache/xpanes/logs
Path to store log files generated by --log option.
It is ignored if the path is explicitly given by --log=.
DEFAULT VALUE: [:ARG:].log.%Y-%m-%d_%H-%M-%S
Format of the log file name generated by --log option.
It is ignored if the format is explicitly given by --log-format=.
Example:
export TMUX_XPANES_LOG_FORMAT="[:ARG:]_mylog.log"DEFAULT VALUE: #[bg=green,fg=black] #T #[default]
It defines format of the pane's title.
See FORMATS section in man of tmux for further details.
It overwrites tmux's pane-border-format in the xpanes's session.
There are some examples here.
DEFAULT VALUE: bottom
It defines location of the pane's title.
It overwrites tmux's pane-border-status in the xpanes's session.
Example:
# Change value from bottom to top
export TMUX_XPANES_PANE_BORDER_STATUS="top"DEFAULT VALUE: \033[41m\033[4m\033[30m Pane is dead: Press [Enter] to exit... \033[0m\033[39m\033[49m
It defines the message that displayed when a process exits with -s option enabled.
The message is underlined black character on the red background (see Ansi escape codes) by default.
Example:
## Set green color
export TMUX_XPANES_PANE_DEAD_MESSAGE='\033[32m=== EXIT ==='DEFAULT VALUE: empty
It forces the tmux version recognized by xpanes.
It is mainly used for testing purposes.
It is also useful if you are using a newer tmux that has not been released yet, or if you have customized the tmux itself and want to suppress unwanted warning messages from xpanes.
Example:
$ tmux -V
tmux customized-3.3
$ xpanes 1 2 3
xpanes:Warning: 'xpanes' may not work correctly! ...
...
$ export TMUX_XPANES_TMUX_VERSION=1.8
$ xpanes 1 2 3=> It works without warning messages.
... and let's play!
Please check out the CONTRIBUTING about how to proceed.
Please note the following points before running the test.
- Run it from outside of tmux session
- Set
allow-renameoption off
Follow this.
## Clone repository together with shunit2 (kward/shunit2)
$ git clone --recursive https://github.com/greymd/tmux-xpanes.git
$ cd tmux-xpanes
## Suppress window name change
$ echo 'set-window-option -g allow-rename off' >> ~/.tmux.conf
$ echo 'set-window-option -g automatic-rename off' >> ~/.tmux.conf
