What is the simplest way to remove a trailing slash from each parameter?

Question

What is the simplest way to remove a trailing slash from each parameter in the \'$@\' array, so that rsync copies the directories by name?

rsync -a         


        

Answer 1

FYI, I added these two functions to my .bash_profile based on the answers found on SO. As Chris Johnson said, all answers using ${x%/} remove only one slash, these functions will do what they say, hope this is useful.

rem_trailing_slash() {
    echo "$1" | sed 's/\/*$//g'
}

force_trailing_slash() {
    echo "$(rem_trailing_slash "$1")/"
}
