Subject: Update cli_checkFiles.sh. Apply to one file only. If you need to apply

this function to many files, create a list of files and use this
function inside a for structure. If the file exists, this function
returns 0, and when file doesn't exist this function returns 1.

This return value is useful to make verifacations based on whether the
file checked exist or not.
