The status information comes out via stderr, so you'll need to redirect that in order to capture it.

Try:

open PIPE, '-|', '"\Program Files\7-Zip\7z.exe" a -r -mx0 -tzip e:\the
+Zip.zip 2>&1' or die $@;;

while( <PIPE> ) {
    # do something with the status output here
}

Update: Here's the test I ran of my suggestion:


Perl> open PIPE, '-|', '"\Program Files\7-Zip\7z.exe" e -so e:\UnxUtil
+sSrc.zip 2>&1 1>nul' or die $@;;

Perl> print <PIPE>;;

I used -so & >nul to avoid the files actually being created, but omit those and they will.

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