Check These Out

List programs with open ports and connections

List your interfaces and MAC addresses
Requires sysfs mounted on /sys - may only be useful for Linux systems. Could also use "printf '%-8s %s\n' $(basename $f) $(cat $f/address)" instead of echo.

Rename files in batch

check open ports without netstat or lsof

finding cr-lf files aka dos files with ^M characters

Google Translate
$ translate [output-language] [source-language] 1) "some phrase" should be in quotes 2) [output-language] - optional (default: English) 3) [source-language] - optional (default: auto) $ translate "bonjour petit lapin" hello little rabbit $ translate "bonjour petit lapin" en hello little rabbit $ translate "bonjour petit lapin" en fr hello little rabbit

-vn removes tha video content, the copy option tells ffmpeg to use the same codec for generating the output
