Script issue, help!

Duffs — Fri, 16 Sep 2005 04:57:04 GMT

Hi,

I have a script (dell_MAN_get.sh) which calls a couple of sub-scripts and basically FTP's particular filespecs from a remote server, sorts these files accordingly (sub-script 'dell_MAN_sort.sh'), checks for rejected files before 'at'ing (rescheduling) itself again and resuming the process.

The problem I have is that the script does not get past the 'dell_MAN_sort.sh' sub-script and as such the files do not get checked for rejects or more importantly rescheduled.

I have attached the two scripts, big points to any effective helpers.

Rgds,
Dermot.

Hi,

........and the problemic sub-script which works corectly but does not return back to the main script.

What does set -x gives for problematic script??

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 05:20:17 GMT

it doesn't give any errors, the script runs perfectly with error code 0. Something must happen upon completion of this sub-script however as nothing else within the main script gets executed afterwards??

Instead of redirecting the output of the at in 'dell_MAN_sort.sh' to /dev/null try redirecting it to a file. You may find the o/s is prompting you for something at that point?

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 06:40:56 GMT

Hi Stephen,

The redirection to the /dev/null has actually been commented out of the script. I can also see from the 'set -x' that the script isn't even reaching this point.

Re: Script issue, help!

Stephen Keane — Fri, 16 Sep 2005 07:41:43 GMT

Sorry, I noticed that immediately after posting. Can you flag the line the script reaches (from your set -x output).

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 08:53:51 GMT

Stephen, yes, the 'set -x' output shows the script reaches the bottom of the dell_MAN_sort sub-script but nothing else. If you look at the subscript I even echo the "fi" at the bottom of the script, which it does.

Re: Script issue, help!

Stephen Keane — Fri, 16 Sep 2005 09:00:36 GMT

So your post "Sep 16, 2005 10:01:04 GMT" has dell_MAN_sort.sh attached - just to be clear.

Does "set -x" echo the "done" as well?

Re: Script issue, help!

Stephen Keane — Fri, 16 Sep 2005 09:03:39 GMT

Worth putting

#!/bin/sh

at the beginning of del_MAN_sort.sh perhaps? Or whatever shell you want to run it under.

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 09:06:41 GMT

Yes thats correct.

It echo's the done also plus I have included an exit 1 in an attempt it force it to revert back to the main script but this doesn't work either.

I have actually included the shell (#!/bin/sh) atthe beginning of the script also but simply haven't included this in my attachment, apologies about that.

Re: Script issue, help!

Stephen Keane — Fri, 16 Sep 2005 09:09:17 GMT

So you get the "done" message, but not the output of "$?" etc? And then the "main" script stops? Or am I misunderstanding?

Re: Script issue, help!

Stephen Keane — Fri, 16 Sep 2005 09:12:22 GMT

Also, when you call dell_MAN_sort.sh from the "main" script have you tried calling it thus

/sbin/sh -x $SCRIPTDIR/dell_MAN_sort.sh

Just as a matter of interest...

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 09:14:32 GMT

Stephen, yes that is exactly what is happening.

I haven't actually called the subscript from the main script in that exact format but I'll give to a go.....

Re: Script issue, help!

Patrick Wallek — Fri, 16 Sep 2005 09:15:49 GMT

Can you post a complete run of the scripts with the "-x' debug option set for both?

Everything looks correct, but seeing the debug output would be helpful.

Hi,

it may not help, but try changing the line

for FILENAME in [ `cat $SRCDIR/man_files` ]; do

to

for FILENAME in $(cat $SRCDIR/man_files); do

as I think the shell will regard the brackets as file names...
Does man_files contain only plain files?

regards,
John K.

Re: Script issue, help!

Duffs — Fri, 16 Sep 2005 11:00:03 GMT

John, thanks for your suggestion but unfortunately that didn't help on this occasion. The host that is running the script is currently down for maintanence and as I am out of the office on Monday I will be happy to try these any further suggestions for this on Tuesday.

Patrick, I will gladly forward you the debug for this on Tuesday.

Stephen, I will also look forward to calling the subscript in the manner you suggested.

Thanks,
Dermot

Dermot,

IMHO, the shell is getting confused between command substitution and test command syntax i.e.

>> for FILENAME in [ `cat $SRCDIR/man_files` ]; do <<

The above command will set the variable FILENAME to the name of the files in the $SRCDIR punctuated by brackets. Change the above for loop to:

>> for FILENAME in `cat $SRCDIR/man_files` ; do <<
OR
>> for FILENAME in $(cat $SRCDIR/man_files) ; do <<

hope it helps!!!

Re: Script issue, help!

john korterman — Mon, 19 Sep 2005 06:38:40 GMT

Hi again Dermot,

could you please show us what dell_file_check.sh does?

and perhaps make an "ls -l" on the the list of files in $SRCDIR/man_files?

regards,
John K.

I am recommending you to make a single script. It will reduce the confusion and time.

Just change script as functions in the same script.

Like,

sort()
{
}
reject()
{
}

If you are not sure then attach all relavent scripts to your requirement here. It will give an opportunity to give quick and effective solution.
