Kill any lingering ssh processes
Also ignoring "sshd" server is necessary since you should not kill ssh server processes.

Display the standard deviation of a column of numbers with awk

Updates your no-ip.org account with curl

ls -qaltr # list directory in chronological order, most recent files at end of list
I find it very handy to be able to quickly see the most recently modified/created files in a directory. Note that the "q" option will reveal any files with non-printable characters in their filename.

concatenate compressed and uncompressed logs
I use zgrep because it also parses non gzip files. With ls -tr, we parse logs in time order. Greping the empty string just concatenates all logs, but you can also grep an IP, an URL...

change up n directories
Change n directories up, without parameters change one up

Temporarily suspend and unsuspend a foreground job
Press ^Z, do what you need to do on the shell, then input % to resurrect the suspended job.

Install pip with Proxy
Installs pip packages defining a proxy

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

ssh autocomplete
Add to your bash profile to minimize carpal tunnel syndrome. Doesn't work with user@hostname but appending "-l user" works fine if needed. Works for ping as well.. complete -W "$(echo `cat ~/.ssh/known_hosts | cut -f 1 -d ' ' | sed -e s/,.*//g | uniq | grep -v "\["`;)" ping
