Check These Out

Display screen window number in prompt
Add this to your $HOME/.bashrc file. It will only set this prompt if it is running inside screen ($WINDOW var is set) Looks like this... $ ion@atomos:~[2]$

MP3 player
I tried a few curses based mp3 players for playing back choir practice songs for my wife. Unfortunately none of the ones I tried were capable of scrubbing a track. Firefox saves the day.

Don't save commands in bash history (only for current session)
Unsetting HISTFILE avoid getting current session history list saved.

Check for Firewall Blockage.
This is just one method of checking to see if an IP is blocked via IP tables or CSF. Simple and to the point. Replace xx.xx.xx.xx with the IP you wish to check.

list files recursively by size

Convert seconds to [DD:][HH:]MM:SS
Converts any number of seconds into days, hours, minutes and seconds. sec2dhms() { declare -i SS="$1" D=$(( SS / 86400 )) H=$(( SS % 86400 / 3600 )) M=$(( SS % 3600 / 60 )) S=$(( SS % 60 )) [ "$D" -gt 0 ] && echo -n "${D}:" [ "$H" -gt 0 ] && printf "%02g:" "$H" printf "%02g:%02g\n" "$M" "$S" }

Convert files from DOS line endings to UNIX line endings
The old dos2unix from sysutils has been deprecated on Debian systems to this tool.

Ease your directory exploration
Usage : tt [OCCURRENCE] tt will display a tree from your actual path tt .svn will display only line containing .svn

shows history of logins on the server
outputs a history of logins on the server (top 10, when piped to 'head'); optional flags: '-a' put the hostname at the end of the line (good for long hostnames), '-i' post the IP instead of the hostname, '-F' put the full login and logout times, rather than short times.

shuffle lines via bash
Using perl in a one-liner is a bit overkill to randomly sort some input. `sort` from coreutils should be enough.
