- Randomize the order of lines in a file and output the result:

`shuf {{path/to/file}}`
2014-09-08 10:27:44 +01:00
- Only output the first 5 entries of the result:
2014-09-08 10:27:44 +01:00
`shuf --head-count=5 {{path/to/file}}`
2014-09-08 10:27:44 +01:00
- Write the output to another file:
2014-09-08 10:27:44 +01:00
`shuf {{path/to/input_file}} --output={{path/to/output_file}}`
