Responsible Changed From-To: freebsd-bugs->billf Billf takes care of stuff in /usr/games Any reason why this patch was never applied? -- (http://tmda.sourceforge.net/) State Changed From-To: open->feedback To submitter: does this patch still apply? Responsible Changed From-To: billf->linimon Assignee did not respond to request for status of this PR, so reassign to the pool. State Changed From-To: feedback->open Submitter's email address bounces. Responsible Changed From-To: linimon->freebsd-bugs random(6) already does this, without the -s. This should be closed. -- Sterling (Chip) Camden | sterling@camdensoftware.com | 2048D/3A978E4F http://camdensoftware.com | http://chipstips.com | http://chipsquips.com could you provide an example how to reproduce the same output (ls /bin | random -s 8) with an unpatched copy of ranom? cheers. alex -- a13x On Mon Aug 9 10, Chip Camden wrote: > Quoth Alexander Best on Tuesday, 10 August 2010: > > could you provide an example how to reproduce the same output (ls /bin | random -s 8) with an unpatched copy of ranom? > > > > cheers. > > alex > > > > -- > > a13x > > > Sure: > > ls /bin | random 8 i don't think this reproduces the exact ouput as `ls /bin | random -s 8`. `random 8` will print each input line with a probability of 1/8th. `random -s 8` on the other hand will print a random line out of every 8 lines of input. this means that for a static number of input lines `random -s 8` will always produce the same number of output lines, wheras the number of lines returned by `random 8` will be different for each run. cheers alex ps: please keep bug-followup@ in the CC field so our conversation gets archived by GNATS. > > -- > Sterling (Chip) Camden | sterling@camdensoftware.com | 2048D/3A978E4F > http://camdensoftware.com | http://chipstips.com | http://chipsquips.com -- a13x Alexander Best <arundel@freebsd.org> wrote: > could you provide an example how to reproduce the same output > (ls /bin | random -s 8) with an unpatched copy of ranom? It's random, so it cannot be reproduced. ;-) But seriously ... If you want random 4 lines out of 32 (or out of any number, for that matter), the following command will do it: $ ls /bin | random -f - | head -4 I agree that this PR can be closed.

Due to this matter and the fact that the patch didn't trigger a lot of interest in more than 10 years I'm closing this PR.

In fact it's a _better_ replacement because the probability is evenly distributed across the whole input. This is not the case for the patch proposed in this PR. > > I agree that this PR can be closed. > > thanks a lot for clearing things up. i'll close the PR right away. Thanks!
