Switch to the previous branch used in git(1)
Very useful if you keep switching between the same two branches all the time.

Convert a bunch of HTML files from ISO-8859-1 to UTF-8 file encoding in a folder and all sub-folders
This is my first attempt at converting all HTML files to UTF-8 file encoding, including all subfolders. Theres probably a much more compact way to do it, but I'm quite proud of it with my windows background ;)

Randomize lines in a file
Works in sort (GNU coreutils) 7.4, don't know when it was implemented but sometime the last 6 years.

Automatically tunnel all ports of running docker instances in boot2docker
It requires https://jqplay.org/, that comes with brew: brew install jq

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"

Recompress all files in current directory from gzip to bzip2
Find all .gz files and recompress them to bz2 on the fly. No temp files. edit: forgot the double quotes! jeez!

Convert all WMF images to SVG recursively ignoring file extension case
This assumes you have the package installed necessary for converting WMF files. On my Ubuntu box, this is libwmf-bin. I used this command, as libwmf is not on my wife's iMac, so I archived the directories containing the WMF files from OS X, ran them on my Ubuntu box, archived the resulting SVGs, and sent them back to her. Quick, simple and to the point. Searches directories recursively looking for extensions ignoring case. This is much more readable and clean than -exec for find. The while loop also gives further flexibility on complex logic. Also, although there is 'wmf2svg --auto', it expects lowercase extensions, and not uppercase. Because I want to ignore case, I need to use the -o option instead. Works in ZSH and BASH. Haven't tested in other shells.

Extract tar.gz file with original permission
-x, --extract, --get extract files from an archive -p, --preserve-permissions, --same-permissions extract information about file permissions (default for superuser) -f, --file=ARCHIVE use archive file or device ARCHIVE -v, --verbose verbosely list files processed

Use AWS CLI and JQ to get a list of instances sorted by launch time
You can do the filtering natively in the aws cli, without using jq (although jq is awesome!)

This is how you should push a string in a command's stdin.
Don't do this: $echo word | command Using a bash "here strings" and "here documents" look leeter than piping echo into the command. Also prevents subshell execution. Word is also expanded as usual.
