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

[BrowserUk]

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

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.

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.
