can-i-use-shell's Issues

The idea

There is caniuse.com for web stating which browsers support what flags.
This repo should start the same collection stating which cli tools support what flags in which versions and implemenations.

For example git --xyz was implemented in version xyz
Or cut --xyz from coreutils works different in macOS than gnu linux

It can then suggest a version guard if statement at the top of the file

if [ $(git --version) -lt 82 ]
then
    echo "Error: your git is too old to run this script since it needs --xyz"
    exit 1
fi

There could also be a mention of a stricter usage of tools.
Ideally you never launch git but only ever absolute paths such as /bin/git
So the tool version does not change during the runtime of the script.

Such as things appearing in PATH or being removed. Due to shims being activated.
PATH being edited. Or current working directory being changed.
