Používáte-li jako já u některých projektů git push pro odesílání aktuální verze projektu na produkci nebo staging, může se vám hodit následující gist. Jedná se o pre-push hook, který vás ochrání před lidskou chybou v deployi. Pokud pushujete na jiný remote než na origin (např. production nebo staging), tak se vás zeptá, jestli to tam opravdu chcete nahrát.
Jednou jsem omylem stagingovou (naštěstí finální) verzi poslala na produkci a už nechci, aby se to opakovalo.

# An additional confirmation if you really want to push to remote (prevents accidental pushes).
#
# This hook is called with the following parameters:
#
# $1 -- Name of the remote to which the push is being done
# $2 -- URL to which the push is being done
#
# Information about the commits which are being pushed is supplied as lines to
# the standard input in the form:
#
# <local ref> <local sha1> <remote ref> <remote sha1>
remote="$1"
url="$2"
# If we have a STDIN, use it, otherwise get one
if tty >/dev/null 2>&1; then
TTY=$(tty)
