Check These Out

recursive transform all contents of files to lowercase
In this way it doesn't have problems with filenames with spaces.

archlinux: check which repository packages have updates available
Shows which packages from the official repositories (not aur) have updates available. For most accurate output, the mirrors and package lists should be up to date.

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"

generate random password
for Mac OS X

Compress and store the image of a disk over the network
Create an image of "device" and send it to another machine through the network ("target" and "port" sets the ip and port the stream will be sent to), outputting a progress bar On the machine that will receive, compress and store the file, use: $nc -l -p | 7z a -si -m0=lzma2 -mx=9 -ms=on Optionally, add the -v4g switch at the end of the line in order to split the file every 4 gigabytes (or set another size: accepted suffixes are k, m and g). The file will be compressed using 7z format, lzma2 algorithm, with maximum compression level and solid file activated. The compression stage will be executed on the machine which will store the image. It was planned this way because the processor on that machine was faster, and being on a gigabit network, transfering the uncompressed image wasn't much of a problem.

dd with progress bar and remaining time displayed

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

Perl Command Line Interpreter
Can also just use the debug mode like this.

List out classes in of all htmls in directory
Lists out all classes used in all *.html files in the currect directory. usefull for checking if you have left out any style definitions, or accidentally given a different name than you intended. ( I have an ugly habit of accidentally substituting camelCase instead of using under_scores: i would name soemthing counterBox instead of counter_box) WARNING: assumes you give classnames in between double quotes, and that you apply only one class per element.

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