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

In zsh you can use the :a modifier.

export DIRECTORY='/some//path/name//'

echo "${DIRECTORY:a}"

=> /some/path/name

This acts like realpath but doesn't fail with missing files/directories as argument.
