Shell Programming and Scripting

Hi all,
We've been trying to find a way to get a command to work within a ksh with no success.
We are attempting to list various files with different hlq's like this

Code:

ls $FileDir/dir/subdir/${triggers}

The $FileDir is set in the script.
The $triggers resolves to

Code:

triggers=sys.file@(.test|.uat|.live|).[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].tg

The command works fine from the command line (It returns the list of files) but within the script is says

Code:

sys.file@(.test|.uat|.live|).[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9].tg not found.

We suspect the problem is the coding of '@' within the shell as it looks like it is taking the @(.test|.uat|.live|) as a literal name rather than expand it into the three different qualifiers.

Any help much appreciated

Cheers

It always does that to any glob which doesn't match a file, so it's unrelated to @. by itself alone, @ has no special meaning to the shell.

I suspect your script runs using a different shell than your login shell. Either that, or they're running with different options enabled.

There may be several reasons for the reported behaviour:
- You are not running the script with a recent bash and thus don't have "extended pattern matching".
- You did not set the extglob option with shopt.
- Your script changed diretory so no files are found.

Cheers RudiC I'll look into that

Extended globbing - for example @(...) - is part of ksh93 (you do not need to turn it on), but not ksh88. Could it be that your shell is an older Kornshell or that it is not ksh93 ?

You say it is a script, how are you running the script?

@RudiC: It is Kornshell, not bash

man bash (4.3.30(1)):

Yes But the question is about ksh not bash. Ksh93 also has extended globbing, with even more functionality than bash and it is on by default, there is no shopt function.
