Re: Re: Perl Idioms Explained

If they don't know that "AUTOFLUSH" flushes the output automatically, they probably don't know what the heck "UNBUFFERED" means.

(And the converse -- if they have any clue what flushing is at all, they probably know what "AUTOFLUSH" means.)

Re^3: Perl Idioms Explained - $\|++ by petrw1 (Initiate) on Apr 13, 2018 at 19:23 UTC
Can you tell me if I need to specify the $\|++ (or equivalent) in "ALL" perl scripts within a process; or only the main driver. I have about 50 perl scripts several layers deep (i.e. "A" invokes "B" which invokes "C" and "D" and "E" etc.....) By the way I have tried it in a few scripts with no luck yet ... the output to my screen still only displays every 50 lines or so. Are they any gotcha's? Thanks Wayne	[reply]

`$\|` works per process. So if you use one script that sources other scripts (e.g. using do `$filename`, require, eval `$string`), once is sufficient. If you start scripts from other scripts using system, exec, qx a.k.a. ``, pipe open (`\|` somewhere in the `open` arguments), each script runs in its own process and thus has its own `$\|`.
