[fe74c7c] | 19 | |
---|
[fc8707b] | 20 | -q, --queue Specify a queue other than the default |
---|
| 21 | -d, --dryrun Just list what would be done |
---|
[ca8acb7] | 22 | -s, --shuffle Randomize the order that the songs are queued in |
---|
| 23 | -r, --recursive Recursively find files if a directory is passed in |
---|
[43ddb7a] | 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) |
