How to automatically update all git repos in a folder

As someone who has many github repo folders on their server I wanted an easy way to update all of them regularly with minimal points of failure so I made this script:

#!/bin/bash

# store the current dir
CUR_DIR=$(pwd)

# Let the person running the script know what's going on.
echo "\nPulling in latest changes for all repositories...\n"

# Find all git repositories and update it to the master latest revision
for i in $(find . -name ".git" | cut -c 3-); do
    echo "";
    echo ""$i"";

    # We have to go to the .git parent directory to call the pull command
    cd "$i";
    cd ..;

    # finally pull 
    # the old name
    git pull origin master;
    # the new PC friendly name
    git pull origin main;

    # lets get back to the CUR_DIR
    cd $CUR_DIR
done

echo "Complete!"

I have it run automatically every 10 minutes using cron

*/10 * * * * cd ~/ && bash ~/update_git_repos.sh

Obviously it would be more ideal if it only ran when a repo was updated but like I said, I wanted less points of failure.
