I have ported bash (version 1.12.1) to Sequent, running DYNIX/ptx 2.x (a Symmetrical Multi Processor version of System V unix), and was unable to get the results mentioned below... What version of bash are we talking about? It might have something to do with the way signals are handled... ----%<----%<----%<----%<---- SNIP ----%<----%<----%<----%<----%<---- [hvdl @ amsqnt]:.../hvdl(339)> bash -version bash -version GNU bash, version 1.12.1 [hvdl @ amsqnt]:.../hvdl(340)> ls -lt | more [1]+ Stopped ls -lt | less [hvdl @ amsqnt]:.../hvdl(341)> fg total 99082 -rw------- 1 hvdl service 2059444 Apr 16 12:00 name1 -rw------- 1 hvdl service 676451 Apr 16 11:11 name2 << etc... >> [hvdl @ amsqnt]:.../hvdl(342)> ----%<----%<----%<----%<---- SNIP ----%<----%<----%<----%<----%<---- It is said that Greg Lehey dared to write: ! ! > I just noticed it, myself.

FWIW, I've tried this on an SNI box (System V.4, R4400). It does much ! the same thing, except that it needs a ^C to get a prompt after the ! ^Z. Looks like it isn't a FreeBSD problem. ! !
