Heroku shortcut - looks for git remotes, infers heroku app name and issues a heroku command

h

#!/bin/bash
remote="$1"
app=`git remote -v | awk -v pattern="^$remote" '{ if (match($1, pattern) && match($2, "git@.*") && match($2, "\:(.*)\.git")) { print substr($2, RSTART+1,  RLENGTH-5); exit 1;}}'`
if [ "${app}" == "" ]; then
    # regex is written in this hack way ("\.com/.*\.git" instead of "[^/]*.git") because Apple awk doesn't support character sets
    app=`git remote -v | awk -v pattern="^$remote" '{ if (match($1, pattern) && match($2, "https") && match($2, "\.com/.*\.git")) { print substr($2, RSTART+5,  RLENGTH-9); exit 1;}}'`
