# I have a two branch develop and master.

# If you have unstaged or not tracked files, script adds these files to stash.
# So you unstash these changes after deploy.

    echo 'Untracked files will be stash automatically.'
    exit 1

Excellent script.
I made temp path configurable. Hope this version helps

I accidentally ran this script and I think It may have deleted some files! Is there a way to undo this?

@akufta the script stashes all changed files and not tracked files. So look at stash for files.
Are you have only master branch? If so this should be couse to error.
I am using master for keeping generated files and develop for keeping posts. I am running this script on develop branch.
