Question

I have few repositories and each have config.php file that contain information about database like password. I have script that connect to database using stuff from that file and need to search back in directory tree so I can call it in every nested directory.

[ -e config.php ] && $(php -r 'require("config.php"); echo "mysql -u".$config["db_user"] . " -p".$config["db_pass"] . " " . $config["db_name"];')

What is easiest way to search back in directory tree using Bash?

Answer 1

This chops off a directory from the end of PWD until it becomes empty. Some care may need to be taken in the presence of links.

S="${PWD}"
while [ -n "${S}" ]
do
    [ -e "config.php" ] && ls $S/
    S=${S%/*}
done
