Re^2: ClearCase Command text in Backticks is ignored

[Deep_Plaid]

Hi Ken,

Thanks so much for your fast reply. Escaping the back slashes in the format option worked! The output using system does the format properly now. Code:

$output = system("cleartool lsco -r -brt p_JOESDRUGS_DT_Int -fmt \"%En
+\\t%u\\n\"");

The zero is still at the end, but I can always chop that off. Output:

.\EDC_Export\Test_file2.txt     mkjohnson
.\EDC_Export\Test_file3.txt     mkjohnson
0

However, I still haven't solved the first issue. I tried your advice, and this solves the problem of recognizing the content of $stream, but the command fails. I also tried it with including the double quotes escaped:

$output = system('cleartool', 'lsco', '-r', '-brt', $stream, '-fmt', '
+\"%En\\t%u\\n\"');

But that still fails. However, a different failure, so I'm getting closer. It's a cleartool error and it reveals it can read $stream. Output:

cleartool: Warning: Type not found: "p_JOESDRUGS_DT_Int".
0

So I am getting closer. I will try playing around with this combination, but any further advice would be greatly appreciated. Thanks again.

If your code is essentially

my $output = system(...);
print $output;

then you should note that system returns the status code returned by the call, not the output of the call. There's no reason to do the print, and probably no reason to capture the return.

I also tried it with including the double quotes escaped

The question I should have included up front is "What is the exact syntax that works on the command line?" If you pass system '\"%En\\t%u\\n\"', I believe it should be equivalent to entering '\\"%En\\t%u\\n\\"' on the CLI, which I think is unlikely to be what you intend.
