set -f set -o noglob Disable file name generation using metacharacters (globbing).

set -v set -o verbose Prints shell input lines as they are read.

Debugging on the entire script. When things don't go according to plan, you need to determine what exactly causes the script to fail. Bash provides extensive debugging features. The most common is to start up the subshell with the -x option, which will run the entire script in debug mode.
