Para Cada in Spanish 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 {} \;All of them are relatively complex. This is where cada can help. Simply do:
cada 'tar xzvf *.tgz'Cada knows how glob expressions work and executes the entire command with subsequent values corresponding to your glob expression. Additionally, users may transform/filter/sort those values using regular Python syntax. Take a look at the documentation.
Requirement: Python >= 3.8
pip install para-cada
