cli_checkFiles Tasks related to file verification are implemented through cli_checkFiles function. This function is exported to centos-art.sh script environment in the very beginning of its execution and will be available all along its execution lifetime. You can use this function inside common and specific functions whenever you need to verify files inside the &TCAR;. The cli_checkFiles is an interface for the test command and answers basic questions like Does location is a regular file? and Does location is directory?. When the answer to such questions is positive, the script passes the test silently and continues its execution. When the answer is negative, the script finishes its execution immediately with an error message. Use the cli_checkFiles function whenever you need to verify the characteristics of different file types (e.g., regular files, directories, links, etc.) inside &TCAR;. cli_checkFiles -d -e -f -h -x LOCATION The cli_checkFiles function accepts the following options: -d Verifies whether LOCATION exists and is a directory. If it doesn't exists or isn't a directory, an error message is printed and the script finishes its execution. Otherwise, if it exists and is a directory, the script continues its execution normally. -e Verifies whether LOCATION exists or not. If it doesn't exist, an error message is printed and the script finishes its execution. Otherwise, if it does exists, the script continues its execution normally. -f Verifies whether LOCATION exists and is a regular file. If it doesn't exists or isn't a regular file, an error message is printed and the script finishes its execution. Otherwise, if it exists and is a regular file, the script continues its execution normally. -h Verifies whether LOCATION exists and is a symbolic link. If it doesn't exists or isn't a symbolic link, an error message is printed and the script finishes its execution immediately. Otherwise, if it does exist and is a symbolic link, the script continue its execution normally. -x Verifies whether LOCATION exists and execution permission is granted. If it doesn't exist or hasn't execution permission, the script finishes its execution immediately. Otherwise, if it exists and has execution permissions, the script continues its execution normally. The value of the LOCATION argument must be an absolute path to the file you want to verify. If such file doens't exists in any supported form, the script finishes its execution with an error message. The cli_checkFiles function is available inside the centos-art.sh script only as part of its execution environment. This function is exported to centos-art.sh script just after executing the script from the command-line and will be available all along the script lifetime. So, you can use this function both in common and specific functionalities of centos-art.sh script. The cli_checkFiles function doesn't create subsequent execution environments.
