Pre-push confirmation
#!/bin/sh
# 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)
else
TTY=/dev/tty
fi
# http://djm.me/ask

# Ask the question (not using "read -p" as it uses stderr not stdout)
