| 15 | -f - Indicates the parameter is a file. |
||
| 16 | -a - Sorts filtered lines by calling the optional [alias] parameter, the alias is passed two lines, $1 and $2, it must compare both and return -1, 0, or 1 to indicate relative sort order of these lines to each other. |
||
| 17 | -x - Excludes matching lines. |
||
| 18 | -n - Prefixes lines with a line number. (the Nth match) |
