Re^4: Can't close pipe to invalid process

The only path I see in the OP is that pointing to the file the executable is meant to process:

/opt/humana/svn/checkouts/rosalind-repo/prod/tmp/testfile.pdf
[download]

The executable name is provided unadorned; so either in the current working directory or to be located via the path environment variable.

But, as I've no knowledge of what the "Jenkins environment" is; it could be me misinterpreting the question.

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority". I knew I was on the right track :)

In the absence of evidence, opinion is indistinguishable from prejudice.

I was talking about `prince`. Since (as OP found out) Jenkins had cleared PATH environment variable, and (supposedly) there was no `prince` executable in the current directory (or the script was running on a UNIX-like system where executables are not run from current directory unless `$PATH` contains `.`), OP thought that `open($fh, "\|-", "prince ...")` should have failed, but it didn't because there was a `$Config{sh}` between Perl and prince in the process tree.
