Check These Out

truncate deleted files from lsof
While the posted solution works, I'm a bit uneasy about the "%d" part. This would be hyper-correct approach: $ lsof|gawk '$4~/txt/{next};/REG.*\(deleted\)$/{sub(/.$/,"",$4);printf ">/proc/%s/fd/%s\n", $2,$4}' Oh, and you gotta pipe the result to sh if you want it to actually trim the files. ;) Btw, this approach also removes false negatives (OP's command skips any deleted files with "txt" in their name).

purge all packages marked with 'rc'
After you install/remove lots of packages, there are many packages marked with 'rc'. This script help you to purge these packages, it will save some spaces from your disk.

Build an exhaustive list of maildir folders for mutt
Of course, you can adjust "Maildir" to your config...

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

url shortner using google's shortner api
First get a api key for google url shortner from here https://developers.google.com/url-shortener/ Then replace the API_KEY in the command

Base conversions with bc
Easily convert numbers to their representations in different bases. Passing "ibase=16; obase=8; F2A" to bc will convert F2A (3882 in decimal) from Hex to Octal, and so on.

Prints line numbers
If you don't have nl on your system, this achieves a similar effect, the default behavior in nl is to not number blank lines, but this does.

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

Find common groups between two users
