bash tricks

dont allow commiting to main branch

#!/bin/sh

branch="$(git rev-parse --abbrev-ref HEAD)"

if [ "$branch" = "main" ]; then
  echo "Hello from .git/hooks/pre-commit"
  echo "You can't commit directly to main branch."
  exit 1
fi

save that to .git/hooks/pre-commit

use one of two binaries:

Create alias if it doesn't already exist:

command -v gdircolors >/dev/null 2>&1 || alias gdircolors="dircolors"

# this may be zsh only…
which glocate > /dev/null && alias locate=glocate

compress and extract shit

7z a -tle files.7z this_stuff.json
7z e files.7z

gzip -k this_stuff.json
gunzip -k files.json.gz
