18 | Usage: gbr [options] [-q QUEUE] FILES |
---|
19 | |
---|
20 | -q, --queue Specify a queue other than the default |
---|
21 | -d, --dryrun Just list what would be done |
---|
22 | -s, --shuffle Randomize the order that the songs are queued in |
---|
23 | -r, --recursive Recursively find files if a directory is passed in |
---|
24 | -n, --number NUMBER Only print NUMBER files, if more than NUMBER are given |
---|
25 | (this will print the first NUMBER files if -s is not given) |
---|
26 | -h, --help Print this message |
