scrap

Various scripts I've written over the years.

installation

git clone https://github.com/shawwn/scrap ~/scrap

# add scrap to PATH
echo 'export PATH="${HOME}/scrap:${PATH}"' >> ~/.bashrc
echo 'export PATH="${HOME}/scrap:${PATH}"' >> ~/.zshrc

examples

mkbin <name>

Make a new scrap script with a predefined bash template. If <name> already exists, the script is edited instead. If you save an empty file, the script is deleted.

mkpy <name>

Make a new scrap script with a predefined python template. If <name> already exists, the script is edited instead. If you save an empty file, the script is deleted.

math <expr>

Evaluate math.

$ math 60*60
3600
$ math 2^64/2^60
16.0000
$ math '2^64/2^(60+1)'
8.0000

narrow [filter1] [filter2] ....

Filter lines by each filter.

A filter is a python regex. NOTE: You must explicitly put whitespace within [ ].

For each line, the line is discarded unless it matches the filter.

If a filter starts with !, all lines are kept except those matching the filter.

The general idea is that you can do <some command> | narrow foo to see all lines containing foo, and <some command> | narrow foo bar to see all lines containing foo and bar, and so on.

This is a very easy way of trimming down output to exactly what you care about.
