Hi,

I'm writing a simple script and am having trouble with wildcards and string searching.

OK, my problem:

I have a script already called "lpck" which polls a pre-defined list of printers and executes the lpstat... command against them to see whether they are up and printing or down.

What I want my new script to do, is assign a variable to the output of the lpck script (easy part):

the_output=`lpck`

Then I want to search the_output for the word "DOWN" which will indicate that one of my printers is not functioning.

Now, I know how to test for numbers etc using the if ... then ... loop, but how do I say:

If [ "whatever the output from lpck is" matches "anything DOWN anythng" ]
then......

else.....

I guess I need to use some sort of wildcard, although I've tried this:

if [ "$printstats" = "*DOWN*" ]

And it doesn't work.

Oh, I'm running AIX 4.3 and AIX 4.2 by the way, both on RS6000's.

Thanks in advance.

Neil.

in ksh ...
  if [[ "$printstats" = *DOWN* ]]
or in ksh/sh
