For loop

The for loop is usually used when you have multiple tasks or commands to execute for each of the entries in an array or want to execute a given command on a finite number of items. In this example, we have an array (or list) containing three elements: file1, file2, and file3. The for loop will echo each element within FILES and exit the script:

#!/bin/bashFILES=( "file1" "file2" "file3" )for ELEMENT in ${FILES[@]}do        echo "${ELEMENT}"doneecho "Echo\'d all the files"
