Note: Export functionality is currently in the experimental stage.
General usage:
version 0.5
- Example: ./LinEnum.sh -k keyword -r report -e /tmp/ -t
OPTIONS:
- -k Enter keyword
- -e Enter export location
- -t Include thorough (lengthy) tests
- -r Enter report name
- -h Displays this help text
Running with no options = limited scans/no output file
- -e Requires the user enters an output location i.e. /tmp/export. If this location does not exist, it will be created.
- -r Requires the user to enter a report name. The report (.txt file) will be saved to the current working directory.
- -t Performs thorough (slow) tests. Without this switch default 'quick' scans are performed.
- -k An optional switch for which the user can search for a single keyword within many files (documented below).
