Create a file/directory with same owner and permissions

mklike

#!/bin/bash
# Create a file / directory with same rights as an exiting one

typeset local

Usage() {
echo Usage $0 -r reference_file|reference_dir new_file|new_dir ...
exit 1
}

while getopts ":r:" option
do
    case "${option}" in
        r)
            reference=${OPTARG}
            ;;
        *)
            Usage
            ;;
    esac
done
shift $((OPTIND-1))

if [ -d $reference ]
then
    mkdir $*
elif [ -f $reference ]
then
    touch $*
else
    Usage
    exit
fi
chown --reference=$reference $*
chmod --reference=$reference $*

I find this useful with sudo,

    sudo mklike -r existing_dir newdir

instead of

    sudo mkdir newdir
    sudo chown ... newdir
    sudo chmod ... newdir
