Using a function with parameters within a for loop

In this short example, we have a function called create_file, which is called within a loop for each file in the FILES array. The function creates a file, modifies its permissions, and then passively checks for its existence using the ls command:

#!/bin/bash
FILES=( "file1" "file2" "file3" ) # This is a global variable

function create_file() {
    local FNAME="${1}" # First parameter
    local PERMISSIONS="${2}" # Second parameter
    touch "${FNAME}"
    chmod "${PERMISSIONS}" "${FNAME}"
    ls -l "${FNAME}"
}

for ELEMENT in ${FILES[@]}
do
        create_file "${ELEMENT}" "a+x"
done

echo "Created all the files with a function!"
exit 0
