Mount folder/filesystem through SSH
Install SSHFS from http://fuse.sourceforge.net/sshfs.html Will allow you to mount a folder security over a network.

Function that outputs dots every second until command completes
Very useful in shell scripts because you can run a task nicely in the background using job-control and output progress until it completes. Here's an example of how I use it in backup scripts to run gpg in the background to encrypt an archive file (which I create in this same way). $! is the process ID of the last run command, which is saved here as the variable PI, then sleeper is called with the process id of the gpg task (PI), and sleeper is also specified to output : instead of the default . every 3 seconds instead of the default 1. So a shorter version would be sleeper $!; The wait is also used here, though it may not be needed on your system. $ echo ">>> ENCRYPTING SQL BACKUP" $ gpg --output archive.tgz.asc --encrypt archive.tgz 1>/dev/null & $ PI=$!; sleeper $PI ":" 3; wait $PI && rm archive.tgz &>/dev/null Previously to get around the $! not always being available, I would instead check for the existance of the process ID by checking if the directory /proc/$PID existed, but not everyone uses proc anymore. That version is currently the one at http://www.askapache.com/linux-unix/bash_profile-functions-advanced-shell.html but I plan on upgrading to this new version soon.

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

Clear your history saved into .bash_history file!
Note the space before the command; that prevents your history eliminating command from being recorded. ' history -c && rm -f ~/.bash_history' Both steps are needed. 'history -c' clears what you see in the history command. 'rm -f ~/.bash_history' deletes the history file in your home directory.

Force logout after 24 hours idle
Shell timeout variables (TMOUT) can be very liberal about what is classified as 'activity', like having an editor open. This command string will terminate the login shell for an user with more than a day's idle time.

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"

find all active IP addresses in a network
Have to run as superuser... but easier and more informational if you are looking for actual devices. Need to install arp-scan.

Get your outgoing IP address
should be very consistent cause it's google :-)

Convert PDF to JPG
Without the bashisms and unnecessary sed dependency. Substitutions quoted so that filenames with whitespace will be handled correctly.

Install pip with Proxy
Installs pip packages defining a proxy
