Print every Nth line (to a maximum)
Thanks to knoppix5 for the idea :-) Print selected lines from a file or the output of a command. Usage: $ every NTH MAX [FILE] Print every NTH line (from the first MAX lines) of FILE. If FILE is omitted, stdin is used. The command simply passes the input to a sed script: $ sed -n -e "${2}q" -e "0~${1}p" ${3:-/dev/stdin} print no output $ sed -n quit after this many lines (controlled by the second parameter) $ -e "${2}q" print every NTH line (controlled by the first parameter) $ -e "0~${1}p" take input from $3 (if it exists) otherwise use /dev/stdin ${3:-/dev/stdin}

Backup (archive) your Gmail IMAP folders.
Copies an entire hierarchy of mailboxes from the named POP3/IMAP/etc. source to the named destination. Mailboxes are created on the destination as needed. NOTE: The 'mailutil' is Washington's University 'mailutil' (apt-get install uw-mailutils). More examples $ mailutil transfer {imap.gmail.com/ssl/user=you@gmail.com}INBOX Gmail/ ; mailutil check imap.gmail.com/ssl/user=you@gmail.com}\[Gmail\]/Spam If you use the utility in the first, append -v|-d flag(s) to the end the commands above (man mailutil).

Get memory total from /proc/meminfo in Gigs

find packages installed from e.g. sid which are newer than those available from e.g. testing when sid is no longer present as a source repo
This is useful if you add sid, install some packages, then remove sid and want to work out which packages you installed from sid that should be removed (e.g. before an upgrade to the new stable). Alternatively you can think of this as "find installed packages that can no longer be installed."

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.

unbuffered tcpdump
Sometimes the question comes up: How to get unbuffered tcpdump output into the next program in the pipe? i.e. if your OS forces you to wait for the buffer to fill before the next program sees any of the output If you use -Uw- then you can't use -A (or -X or -XX) at the same time. When the question comes up, I've never seen anyone suggest this simple solution: chaining 2 tcpdump instances.

Create a new file

Send your svn diff to meld
If you like to view what has been changed between revision 100 and the BASE on FILE. Meld will give you a nice overview.

Add forgotten changes to the last git commit
It's pretty common to forgot to commit a files, be it a modification, or a brand new file. If you did forget something, git add the files you want, and then git commit --amend. It will essentially redo the last commit, with the changes you just added. It seeds the commit message with the last commit message by default. You probably shouldn't do this if you've already pushed the commit.
