[SLUG] awk, vim input
OK I am a bit stumped, and awk is certainly not my forte I have an awk script the uses the system(vim variablehere) function to call vim, the point being to edit a file manually and then get back to the awk script. Now when this runs I get a Warning: Input is not from the terminal from vim, and then it jumps straight back to the awk script. I am guessing that a filehandle is open or some sort or redirection is causing this but I am not to sure. Does any-one have any ideas? Is there anyway I can get some debugging information from awk and vim to find out what is going on.

Is there anyway I can get some debugging information from awk and vim to find out what is going on. I don't know much about awk, but my reading of that error message is that vim is expecting to be started on a pty and awk's system call is not providing it with one. It's kinda tricky to get around. If system doesn't provide a pty (and it doesn't seem to) there isn't really a way you can make it. Which I find more than a little surprising, although I guess it makes sense in the context of what awk is. I hate advising people to change the brand of car they drive when there's a small problem with their current one, but I don't think (from my brief reading of the man page) that awk will let you do what you want. Can some awk guru please correct me on this? I'd recommend using perl for this. Which I realise is probably not particularly helpful. If you can give us a bit more info about what you need done then we might be able to give you some perl snippets to help you on your way. Hope that isn't completely unhelpful :) James. -- SLUG - Sydney Linux User's Group - http://slug.org.au/ More Info: http://lists.slug.org.au/listinfo/slug

Unfortunately we don't run X . A point I should of made is that this script works fine on a sco unix box running nawk. -Original Message- From: [EMAIL PROTECTED] [mailto:slug-admin;slug.org.au]On Behalf Of Angus Lees Sent: Friday, 18 October 2002 8:48 AM To: Daniel Harper Cc: SLUG Subject: Re: [SLUG] awk, vim input At 18 Oct 2002 07:20:22 +1000, James Gregory wrote: On Thu, 2002-10-17 at 16:51, Daniel Harper wrote: I have an awk script the uses the system(vim variablehere) function to call vim, the point being to edit a file manually and then get back to the awk script.
