pipe

See the current Perl documentation for pipe.

Here is our local, out-dated (pre-5.6) version:


pipe - open a pair of connected filehandles



pipe READHANDLE,WRITEHANDLE



Opens a pair of connected pipes like the corresponding system call. Note that if you set up a loop of piped processes, deadlock can occur unless you are very careful. In addition, note that Perl's pipes use stdio buffering, so you may need to set $| to flush your WRITEHANDLE after each command, depending on the application.

See Open2, Open3, and Bidirectional Communication for examples of such things.

[Lady_Aleena]: Your Mother, how would that work? I'm having a hard time understanding the pod.
[Your Mother]: $dir->chidren, grep {} $file->slurp &c &c. :P
[Your Mother]: Stick with what you know. Or post a SOPW and if it's not complicated I guarantee someone will answer; me if it's straightforward and no one else gets it better first.
