Re^4: Multiple system commands in parallel

The "/B" option appears to do what you want? (ignore CTL-C?)

No. It doesn't:

C:\test>perl -e" system 'start /b c:/perl64/bin/perl.exe -E\"$^|=1; sa
+y ++$i while sleep 1\"'; sleep 1000"

That's both processes aborting.

Contrast:

C:\test>perl -e" system 'start /min c:/perl64/bin/perl.exe -E\"$^|=1; 
+say ++$i while sleep 1\"'; sleep 1000"

The initial process terminates, the second process continues to run, outputting to its own window.

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.
