How is this script being run when not from terminal? Cron or the like? Make sure its PATH is up to par with yours, things run by cron and other such automatic tools get quite minimal PATHs.

Run from command line, ie sh script.sh

Could you give an example, not a word description, but a code sample, with code tags. Something like:
Code:
$ ls
aaa bbb

Code:
$ cat test.sh
ls

Code:
$ ./test.sh

That way, you are invoking /bin/sh, an entirely different shell, and you are bypassing a shebang if it is present in your script. You should run it as bash script.sh ( the same holds true for Linux by the way ) or make the script executable, use a shebang and execute it as /path/to/script.sh.

shebang in all scripts
Code:
#!/bin/bash

CRAP, i just tested using the same test files with the executable now set and several of these now work. I thought the shebang overrode however it was called. I've used sh anyscript.sh for years on my bash scripts. Of course it has been a while since i've been on solaris with any frequency.

Funny thing is my case still doesn't work.
Code:
#!/usr/bin/bash
echo $SHELL

while read myDomain
   do
      myCounter=`cat domain_file.txt |awk '{print $3}'|grep "^$myDomain"|wc -l`
      echo $myCounter
      case $myCounter in
          0) echo "found a 0";;
          1) echo "found a 1";;
          2) echo "found a 2";;
          *) echo "everything else";;
      esac
   done < domains_only.txt

Gets the counts right but everything falls through to the all other entry.

Code:
/bin/bash
7
everything else
3
everything else
4
everything else
1
everything else

Hi, using sh script on Linux was also incorrect but your particular distribution may have been more foregiving..

wc -l adds spacing in front of the result, that is why the case statement goes wrong. Try using grep -c instead:
Code:
 ... |grep -c "^$myDomain"

Thanks, I really appreciate that. My CentOS and upgraded packages must have been fixing a lot of crap for me.
