Due to my bad english in my two last articles it seems like I mislead most of you out there, sorry about that :(. But one answer I got indicates that it seems to be something wrong with the command 'rm'. So it is not really a C-shell or rsh problem (or my mistake :) ). I share this answer with you and asks if someone can answer the question why the command 'rm' don't work as expected. (is it a bug or a feature :) ? ) /Bertil From bortz@cnam.cnam.fr Thu Nov 5 17:44:11 1992 Date: Thu, 5 Nov 1992 17:43:56 +0100 From: Stephane Bortzmeyer <bortz@cnam.cnam.fr> To: euabem@eua.ericsson.se Cc: bortz@cnam.cnam.fr, letondal@cnam.cnam.fr, wandel@cnam.cnam.fr Subject: Re: C-Shell question Content-Length: 1355 A few minutes after I replied, I followed my own advice and wrote the following script: #!/bin/csh /bin/rm $1 if ( $status != 0 ) then echo 'My damned script failed' exit 1 endif echo 'Yeah, I did it' exit 0 That's really amazing, but when I run it interactively, it works in both cases (file exists or not) and when it's run under 'rsh', the $status after rm is always 0!!! (I can see that because of the message.) I simply don't understand. I'm working on it (Cc: people can help me, do they?). This script has the correct behaviour if I replace 'rm' by another command (like 'mv'). Therefore, I suspect a problem with 'rm' which apparently doesn't set $status if not run from a tty.

But how can that happen ? How can the result code of rsh be stored > in the $status variable before rsh has executed all of the script ? There is something funny with 'rm'. If I write the following script: #!/bin/csh /bin/mv $1 trash if ( $status != 0 ) then echo 'My damned script failed' exit 1 endif echo 'Yeah, I did it' exit 0 and execute it when the file given as $1 doesn't exist, everything is fine. I get the message 'My damned script failed' when I launch it interactively or threw 'rsh'. If I replace 'mv' with 'rm', I ALWAYS GOT THE MESSAGE 'Yeah, I did it' wether $1 exists or not, as soon as the script is used by 'rsh'! Other commands behave as 'mv'. Now, there's clearly something wrong with 'rm'. Is it possible it doesn't set $status when run without a tty???
