# Add this to your .bashrc and source it (source ~/.bashrc)
# Example: forallsubdirs basedir commands
#   - forallsubdirs . "ls | wc -l; git status"
#   - forallsubdirs . "git fetch --all; git merge --ff-only"
# Note:
#   - To include hidden directories (starting with a "."), set the dotglob option in Bash: shopt -s dotglob
#   - Silencing job control (see comments) is only partially possible, in certain cases job control output will still be printed (see https://stackoverflow.com/a/38278291/202504).
