RE: shell script error





I think that by changing the command, you worked around the problem.

the real solution is to look at the syntax of the command "test"  which is
written here as "[" and "]"
[  "whatever you want tested" ] is an alternative way of writing test
"whatever you want tested"
now,  knowing that the brackets are a command,  it is clear that it needs
spaces around the brackets!  ("echosomething" is different from "echo
something")
i didn't see any in your original failing commandline.

BTW the final fgrep solution without test is nicer though

Kind Regards,
Matthijs Sneijders
