Assumes @output is populated from your source; prints to console: `for (0..9) { print $output[rand($#output)] . "\n"; }` [download] Printing to your `final_output.txt` file is left as an exercise for the student (since you've already solved that). This is likely to select duplicate_lines to your final file, which is still permitted by your spec (but which -- I think -- is not actually your intent). Search the Monastery for `unique` or `@seen` and similar for the many solutions to avoiding duplication. There is not need to create an `output` file (thereby eating cycles and disk space); do your initial selection from the source to an array `@output`.	[reply] [d/l] [select]
