Hi again,
I'm digging out this thread cause it seems that my problem has been only
partially solved. Indeed "my @myout = `program file`;" can save the output
of my program to an array for parsing but this doesn't happen when I use
programs with output that cannot be redirected to a file (i.e. error
messages). In my first message I describe how I can achieve that in bash
using the >$ operator :
apbs input.in >$ output.txt # '>' doesn't work here
How can I block the output of that program when invoked from a perl script?
The case here is that this script is run by a java program multiple times
concurrently, and the java program also reads it output using buffered
readers which overflow with useless data printed by apbs program as shown
above, which results to a crash.
thanks in advance,
Tom
