Check These Out

cat a bunch of small files with file indication
If you have a bunch of small files that you want to cat to read, you can cat each alone (boring); do a cat *, and you won't see what line is for what file, or do a grep . *. "." will match any string and grep in multifile mode will place a $filename: before each matched line. It works recursively too!!

Watch the progress of 'dd'
The 'dd' command doesn't provide a progress when writing data. So, sending the "USR1" signal to the process will spit out its progress as it writes data. This command is superior to others on the site, as it doesn't require you to previously know the PID of the dd command.

Quickly ping range of IP adresses and return only those that are online

Download Youtube video with wget!
Nothing special required, just wget, sed & tr!

fetch all revisions of a specific file in an SVN repository
exported files will get a .r23 extension (where 23 is the revision number)

Grep syslog today last hour
Uses date to grep de logfile for today and uses it to get the last hour logs. Can be used to get last minute logs or today's logs.

Matrix Style
Solves "tr" issues with non C-locales under BSD-like systems (like OS X)
