Check These Out

Unzip multi-part zip archive
Assuming you have a multi-part archive like "archive.zip archive.z01 archive.z02 ...", unzip will not handle these correctly. If you "fix" the parts into one big file with zip -F before, it works.

Jump up to any directory above the current one
Usage: upto directory

list block devices
Shows all block devices in a tree with descruptions of what they are.

run command on a group of nodes in parallel redirecting outputs
Do the same as pssh, just in shell syntax. Put your hosts in hostlist, one per line. Command outputs are gathered in output and error directories.

Using ASCII Art output on MPlayer
Not so useful. Just a cool feature.

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"

Configuring proxy client on terminal

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" }

Using vim to save and run your python script.
This will save and execute your python script every time your press the F5 function key. It can also be added to your .vimrc: autocmd BufRead *.py nmap :w^M:!python % NOTE: the ^M is not just caret-M, it can be created by type: ctrl-v ctrl-m

List the Sizes of Folders and Directories
I wanted an easy way to list out the sizes of directories and all of the contents of those directories recursively.
