Part 1:
So first we have to create the config file for ssh so we use the command cd ~/.ssh/ then we use touch config to create the config file within the ssh directory.
Then, we use vim config to edit the config file and we paste in the necessary info. Here is what this looks like:
We press Esc followed by Enter and :wq to save all our edits once we are done.
Now let's try to log into ssh. Instead of typing out the long username part, all we need is ssh ieng6 which then uses the config file to get the info of our account. Here is a screenshot of what I typed:
Now let's try to copy a file from our local repository onto the remote repository using scp. Usually, we would have to type scp [filename] [email protected]:~/ as the command, but we can use the alias - ieng6 so we don't have to type all that down. Here is what it will look like with a test file:
Part 2
Here is the ssh key on github:
Here is a look at the files within ~/.ssh/ where the public key for the github ssh is stored as well as the private key.
The id_rsa_github.pub is where the public ssh key is stored in and id_rsa_github is where the private key is stored on my local machine.
Now to commit/push changes from our remote repository, we need to enter the following line:
The stuff after git remote set-url origin is copied from a test repo I made. This link is different from an actual link. Rather it is an ssh connection to that repo, so you need to click on ssh and then copy.
Then after we've established that link, we can use the normal commands of
git add --allgit commit -m ""git push
Here is the link to the test repository:
Part 3
For copying an entire directory, we can use the command scp -r . ieng6:~/markdown-parse as shown below:
Then to check that it has copied, we can again use ssh ieng6 to log into our remote account. Here is the ls of the directory we copied.
Then we can run this on the remote server using the junit versions of javac and java respectively.
We can also use a singular command to both copy a directory and run it. Let's try it with markdown-parse. I'm going to use the command rm -r . markdown-parse to delete the entire directory off the remote computer so we can use a singular command to copy and run the tests. Here is the command:
scp -r . ieng6:~/markdown-parse; ssh ieng6 "cd ~/markdown-parse; javac -cp .:lib/junit-4.13.2.jar:lib/hamcrest-core-1.3.jar MarkdownParseTest.java; java -cp .:lib/junit-4.13.2.jar:lib/hamcrest-core-1.3.jar org.junit.runner.JUnitCore MarkdownParseTest"
Here is the run:
