If this script file "test.sh" will be used as an independent executable file, to make it work, you need to put "shopt -s extglob" at the beginning of the file as Greg explained in the other reply. If the script file is supposed to be sourced by another file where "extglob" is enabled, you don't have to set "shopt -s extglob" again at the beginning of the file. However, even if you make sure that "extglob" is enabled when the script file is parsed in real situations as described above, "--pretty-print" still doesn't work because it doesn't execute the file at all. To parse and print a file with the actual set of shell options that the file is supposed to be parsed, you need to set them in the command-line options of Bash. In the present case, you can run it in the following way: $ bash --pretty-print -O extglob test.sh -- Koichi
