------------------------


The first mandatory argument to the script "load_sge_config.sh" is the name of the directory with the old configuration. This option is not
listed in the output:

Usage: load_sge_config.sh [-log I|W|C] [-mode upgrade|copy] [-newijs true|false] [-execd_spool_dir <value>] [-admin_mail <value>]
[-gid_range <integer_range_value>] [-help]

When this first argument it not a directory, the execution should stop. Instead due to the executed "shift" in the script, follow up options
will be interpreted in the wrong way as they are forwarded to other commands:

$ /usr/sge/util/upgrade_modules/load_sge_config.sh -log I
cp: invalid option -- o
Try `cp --help' for more information.
chmod: cannot access `/tmp/sge_backup_2010-10-24_15:13:13/*': No such file or directory
Invalid argument \'I\'
