Okay I stand corrected in that order matters. That said, I honestly can't remember ever seeing 2>&1 not coming at the end of the command line, probably because doing so seems to indicate that it won't be captured to STDOUT as one desires.

~/stuff > cat JGBtest.txt 
Just a starting point

~/stuff > perl foobar.pl 2>&1 >>JGBtest.txt
Going to STDERR
~/stuff > cat JGBtest.txt 
Just a starting point

Normal STDOUT
~/stuff > perl foobar.pl 2>&1 >>JGBtest.txt | grep STD
Going to STDERR
~/stuff > perl foobar.pl 2>&1 | grep STD
Going to STDERR
Normal STDOUT
~/stuff >

With all of the foregoing comments by both you and me in mind, I think you're first comment implies that it must come first in order to be captured. But in the interest of being complete even if I'm wrong, I included the final tests that does actually demonstrate what is happening on the command line (though it is not intuitive.) Also, it is possible that setting $| = 1; might alter the output ordering.

You must always remember that the primary goal is to drain the swamp even when you are hip-deep in alligators.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
