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

You can use the ${parameter%word} expansion that is detailed here. Here is a simple test script that demonstrates the behavior:

#!/bin/bash

# Call this as:
#   ./test.sh one/ two/ three/ 
#
# Output:
#  one two three

echo ${@%/}
