When feeling down, this command helps
$ sudo apt-get install sl $ man sl

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Are there any words in the English language that use at least half of the alphabet without repeating any letters?
This is the most straightforward approach: first regexp limits dictionary file to words with thirteen or more characters, second regexp discards any words that have a letter repeated. (Bonus challenge: Try doing it in a single regexp!)

Self-referential use of wget.

Download from Rapidshare Premium using wget - Part 2
The download content part. NOTE: the '-c' seems to not work very well and the download stuck at 99% sometimes. Just finish wget with no problem. Also, the download may restart after complete. You can also cancel. I don't know if it is a wget or Rapidshare glitch since I don't have problems with Megaupload, for example. UPDATE: as pointed by roebek the restart glitch can be solved by the "-t 1" option. Thanks a lot.

unrar all part1 files in a directory

For example, to remove line 5 from foo, type: vi +5d +wq foo

Validate a file using xmllint. If there are parser errors, edit the file in vim at the line of the first error.

Using numsum to sum a column of numbers.
if you, like me, do not have the numsum, this way can do the same.
