## Functions
## Named Functions | Function | Description |
These are used by some of the other functions to provide flexibility |-------------|-----------------------------------------------------------------------------------------------------------------------|

| Function | Description | | psgrep | List all processes that match the pattern input after the command |
|-------------|---------------------------------------------------------------------------------------------------------------------------------------| | killit | Kills any process that matches a regular expression passed to it |
| retval | Returns the first argument or a '.' if no arguments are specified | | tree | List contents of directories in a tree-like format (if tree isn't installed) |
