# LinEnum

For more information visit www.rebootuser.com

Note: Export functionality is currently in the experimental stage.

General usage:

version 0.982

* Example: ./LinEnum.sh -s -k keyword -r report -e /tmp/ -t 

OPTIONS:

* -k	Enter keyword

* -e	Enter export location

* -t	Include thorough (lengthy) tests

* -s	Supply current user password to check sudo perms (INSECURE)

* -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.

* -s Use the current user with supplied password to check for sudo permissions - note this is insecure and only really for CTF use!

* -k An optional switch for which the user can search for a single keyword within many files (documented below).

See CHANGELOG.md for further details
