RE: [vchkpw] Multiple Independent Pipes
Correct me if I am wrong: If you do this in a .qmail: (one line, no line break) | script1.pl | script2.pl (here the result piped into script2.pl depends on the output of script1.pl) That's different from: (two lines, one line break) | script1.pl | script2.pl (here both deliver independent results) Correct?
