Motivation

In Spanish, Para Cada means For Each. The tool executes your command for each file selected using glob expression(s).

Why? Let’s say you have multiple .tgz archives and you would like to extract them in one shot. Some of the options available in bash are:

ls *.tgz | xargs -IT tar xzvf T
for T in *.tgz; do tar xzvf $T; done
find . -type f -name '*.tgz' -exec tar xzvf {} \;

Each of them is relatively complex. This is where cada can help. Simply do:

cada 'tar xzvf *.tgz'

Cada knows where glob expression is. It executes entire command with subsequent values corresponding to this expression:

Additionally, user may transform/filter/sort those values using regular Python syntax.

Installation
