    You are opening the file for each line, overwriting the previous output. Open it just once before entering the loop.

      Unfortunatelly, still doesn't work. Now, I am getting empty file ;/
      my @tab; open MODULE, "perldoc -m ModuleX|" or die "Failed to open pipeline +($!)"; open(X,"> xxx_dump.txt")|| warn "Fail: ($!)"; while (<MODULE>) { @tab = split; foreach $_ (@tab) { print X $_; } } close X; close MODULE;
      What is wrong ? Maybe perldoc -m ModuleX doesn't work with used modules ?
        Why did you introduce @tab and the inner loop? This works for me:
        open MODULE, "perldoc -m ModuleX |" or die "Failed to open pipeline($! +)"; open(X,"> xxx_dump.txt")|| warn "Fail: ($!)"; while (<MODULE>) { print X $_; } close X; close S;
