za is a tool for running a command on multiple files with the parameters specified to the program configurable by pattern matching. If you routinely work on many files whose filenames follow patterns, this might be a useful tool to you. No more long commandlines with combinations of find, sed, awk, xargs, etc.!
# Display all man pages starting with 'font' and their manpage sections
$ za '/usr/share/man/man[0-9]/font(*).(*).gz' echo 'font$1 in section $2'
# Move files into subdirectories according to their filename
# ex. holiday_01.jpg holiday_02.jpg newyears_01.jpg newyears_02.jpg -> holiday/01.jpg holiday/02.jpg newyears/01.jpg newyears/02.jpg
$ za '(*)_(*).jpg' mv '$f' '$1/$2.jpg'
za requires only zsh. Just put it somewhere on your $PATH. There also is a manpage you might like to install.
