I have 2 suggestions to help you debug.

1. Use the full path for the system commands. I.e. gzgrep and grep.
2. Start small. Cut your command down to just gzgrep "00380-1037" <specific file without *> Then once you verify that command works (if it doesn't, I would suggest you have a fundamental problem which needs addressing), add on to it until you find a spot that doesn't work. Then you know what the problem is more likely to be.
