26 usage: $PROGNAME options
27
28 Program deletes files from filesystems to release space.
29 It gets config file that define fileystem paths to work on, and whitelist rules to
30 keep certain files.
31
32 OPTIONS:
33 -c --config configuration file containing the rules. use --help-config to see the syntax.
34 -n --pretend do not really delete, just how what you are going to do.
35 -t --test run unit test to check the program
36 -v --verbose Verbose. You can specify more then one -v to have more verbose
37 -x --debug debug
38 -h --help show this help
39 --help-config configuration help
40
41
42 Examples:
43 Run all tests:
44 $PROGNAME --test all
45
46 Run specific test:
47 $PROGNAME --test test_string.sh
48
49 Run:
50 $PROGNAME --config /path/to/config/$PROGNAME.conf
51
52 Just show what you are going to do:
53 $PROGNAME -vn -c /path/to/config/$PROGNAME.conf
