Various scripts I've written over the years.
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
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.
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.
Evaluate math.
$ math 60*60
3600
$ math 2^64/2^60
16.0000
$ math '2^64/2^(60+1)'
8.0000
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.
