Bash Linux - git pull for all directories (update all repository folders)

gitpullall.sh

ls -R -d */.git | cut -d'.' -f1 | xargs -P10 -I{} git -C {} pull

# make sure to run it on the folder that have all those repositories that needs to be updated

to make an alias, so it could be run in a single simple command: gitpullall

if grep -q "alias gitpullall" ~/.bashrc; then
    sed -i '/alias gitpullall/d' ~/.bashrc
fi

cat <<EOF >> ~/.bashrc
alias gitpullall='ls -R -d */.git | cut -d'.' -f1 | xargs -P10 -I{} git -C {} pull'
EOF

source ~/.bashrc

clear && echo "Now 'gitpullall' is a command to update all repositories folder."
