Check These Out

Export unpushed files list

kill process by name
Or even easier, if it's available: $ killall firefox I have no idea why you would want to rely on two unusual dependencies to do something that can be done a hundred ways from coreutils...

Kill all processes belonging to a user

Convert records in columns to csv

Get your Firefox bookmarks
Extracts yours bookmarks out of sqlite with the format: dateAdded|url

Pick a random line from a file

List programs with open ports and connections
I prefer to use this and not the -n variety, so I get DNS-resolved hostnames. Nice when I'm trying to figure out who's got that port open.

Change the primary group of a user

Rename files in batch

List latest 5 modified files recursively
The output format is given by the -printf parameter: %T@ = modify time in seconds since Jan. 1, 1970, 00:00 GMT, with fractional part. Mandatory, hidden in the end. %TY-%Tm-%Td %TH:%TM:%.2TS = modify time as YYYY-MM-DD HH:MM:SS. Optional. %p = file path Refer to http://linux.die.net/man/1/find for more about -printf formatting. ------------------------ sort -nr = sort numerically and reverse (higher values - most recent timestamp - first) head -n 5 = get only 5 first lines (change 5 to whatever you want) cut -f2- -d" " = trim first field (timestamp, used only for sorting) ------------------------ Very useful for building scripts for detecting malicious files upload and malware injections.
