processes per user counter
enumerates the number of processes for each user. ps BSD format is used here , for standard Unix format use : ps -eLf |awk '{$1} {++P[$1]} END {for(a in P) if (a !="UID") print a,P[a]}'

It decripts all pgp files in a selection folder and move the output into a file.

Stream and copy a video from lan
Requires a listening port on HOST eg. "cat movie.mp4 | nc -l 1356 " (cat movie.mp4 | nc -l PORT) Useful if you're impatient and want to watch a movie immediately and download it at the same time without using extra bandwidth. You can't seek (it'll crash and kill the stream) but you can pause it.

Creates a SSHFS volume on MacOS X (better used as an alias). Needs FuseFS and SSHFS (obvioulsly).
To make it even more practical, make sure you can login to the ssh server using a keypair.

find files ignoring .svn and its decendents

list files recursively by size

Set name of windows in tmux/byobu to hostnames of servers you're connected to
*I run this with byobu as as a custom status bar entry that runs every 10 seconds by putting it in a script here: $ .byobu/bin/10_update_windows There's no output to stdout, so nothing is displayed on the status bar. *Presumes that #{pane_title} is set to the hostname or prompt containing the host name. In my case, it's in this format: $ $USER@$HOSTNAME:$PWD The sed commands may need to be modified if your pane_title is different. *If you want to strip out a common part of a hostname, add the following before '| uniq' $ -e 's/[COMMON PART]//' I use that to strip out the domain of the servers I connect to, leaving the subdomain.

Ping a URL sending output to file and STDOUT
The tee (as in "T" junction) command is very useful for redirecting output to two places.

Reset terminal that has been buggered by binary input or similar
