Any developers using bash/zsh shell and git can use this code snippet to effectively git fetch when entering a directory:

function chpwd {
GIT_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)

if [ -n "$GIT_ROOT" ]; then
FETCH_STAMP_FILE="$HOME/.cache/chpwd_git_fetch_$(echo "$GIT_ROOT" | tr '/' '_')"
if [ ! -f "$FETCH_STAMP_FILE" ] || [ $(find "$FETCH_STAMP_FILE" -mmin +10) ]; then
({ git fetch --all --quiet && touch "$FETCH_STAMP_FILE"; } > /dev/null 2>&1 &)
fi
fi
}

This snippet acts like a lightweight background updater, seamlessly integrating with your shell navigation to keep your local metadata fresh, reduce manual fetches and out of date merges. #til
