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/bashFILES=( "file1" "file2" "file3" ) # This is a global variablefunction 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"doneecho "Created all the files with a function!"exit 0
