shellutils

Various shell utilities

This repository contains various small posix-ish shell utilities I use. It avoids googling around basic things that I rarely use. There are usually filters to commands "as-is", without argument checking.

You can see the help and examples for each commands by issueing <command> -h. Some scripts have external dependencies, please read the source.

Installation / Usage

Each script can be tweaked to run independently, but by default it will require the __vars script in the same directory of the said script.

I would recommend, especially given the small size of the repo, of just adding the shellutils directory to your PATH.
