Re^3: Passing commands to subroutines

[graff]

Given that you're facing a problem with tricky file names, the easiest substitute I could imagine for fixing a line of code like this:

system("program $ref_file > $outfile");

would be to do it like this:

open( PROG, "-|", "program", $ref_file ) or die "can't launch 'program
+' on $ref_file: $!\n"

open( OUT, ">", $outfile );
while (<PROG>) {
    print OUT;
}
close PROG;
close OUT;

That ought to take any sort of goofy file name safely in stride (for both input and output files).

Probably easier to use one of the IPC:: modules, maybe IPC::Cmd
