Find the cover image for an album
This bash function uses albumart.org to find the cover for an album. It returns an amazon.com url to the image. Usage: albumart [artist] [album] These arguments can be reversed and if the album name is distinct enough, it may be possible to omit the artist. The command can be extended with wget to automatically download the matching image like this: $ albumart(){ local x y="$@";x=$(awk '/View larger image/{gsub(/^.*largeImagePopup\(.|., .*$/,"");print;exit}'

Attach screen over ssh
Directly attach a remote screen session (saves a useless parent bash process)

Add a progress counter to loop (see sample output)
For this hack you need following function: $ finit() { count=$#; current=1; for i in "$@" ; do echo $current $count; echo $i; current=$((current + 1)); done; } and alias: $ alias fnext='read cur total && echo -n "[$cur/$total] " && read' Inspired by CMake progress counters.

Write comments to your history.
A null operation with the name 'comment', allowing comments to be written to HISTFILE. Prepending '#' to a command will *not* write the command to the history file, although it will be available for the current session, thus '#' is not useful for keeping track of comments past the current session.

Convert all .flac from a folder subtree in 192Kb mp3
find . -type f -iname '*.flac' # searches from the current folder recursively for .flac audio files | # the output (a .flac audio files with relative path from ./ ) is piped to while read FILE; do FILENAME="${FILE%.*}"; flac -cd "$FILE" | lame -b 192 - "${FILENAME}.mp3"; done # for each line on the list: # FILE gets the file with .flac extension and relative path # FILENAME gets FILE without the .flac extension # run flac for that FILE with output piped to lame conversion to mp3 using 192Kb bitrate

Query Wikipedia via console over DNS
Shorter version, works with multiple words.

iso-8859-1 to utf-8 safe recursive rename
This command is a powerful "detoxifier" that eliminates special chars, spaces and all those little chars we don't like. It support several "sequences" so be sure to check your /usr/local/etc/detoxrc while at it... and maybe define your own
