[Anthill-pro] Shell and failing script doubt

[emerson cargnin]

Hi All

I have a job library to pre-process our resources depending on the
environment. I then run a shell script to check if there is any
property not merged. I use the following shell script:

egrep @[a-zA-Z0-9__]+@ ./target/resources/*.*

This shouldn't return anything if all properties are merged (no @XXX@
left in the files). I then execute the following beanshell failing
script:

return Fail.unless(
   Logic.and(
    Logic.not(Output.contains("target/resources/")),
     ExitCode.is(0)
    )
   )

because there is no pattern string to verify for failing, then I check
if the root folder appears on the log and fail based on this.

Now... It happens that it is failing even if when I run it manually it
doens't returns anything. I'm suspecting that the command is present
on the log as well, which then makes the script fail as if it was the
result of the command.

How could I change it so that it will fail only when I get any results
from my script?

Thanks
