I'm new to Perl and I just got a position at a company where we use a couple of Perl scripts to both set or reset passwords and add user accounts. These come in handy when users request accounts on multiple servers. A guy who no longer works there wrote at least one of the scripts and I am told that he was a really a hot programmer. In looking over the programs, I was curious about a couple of things. One was the use of this statement: "$| = 1;". Is there any special meaning of the $| (dollar-pipe) variable? The other question concerned this construct: "open(LFD, ">abc.log");". My question here is that I can't find an example of open being used in this syntax and was also wondering whether LFD had any special meaning. Admittedly, my primary resources so far are Learning Perl and Intermediate Perl, both by O'Reilly.
