This is a really nice, clean version of the script. Excellent work!

Well I have to admit that I'm really puzzled at this point! Because I cannot find "show" nowhere on this system. It only works if you 1) ssh into the box and operate within the proprietary netscaler environment or 2) if you issue the commands remotely via ssh.

If I execute a "shell" command within the netscaler software to get to a unix shell, this is the result of my best efforts to find the command called "show".

root@ns# find / -name "show" -print root@ns# show -bash: show: command not found root@ns# echo $PATH /netscaler:/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/usr/local/bin:/ +usr/local/sbin:. root@ns# grep -ri show $PATH grep: /netscaler:/bin:/sbin:/usr/bin:/usr/sbin:/usr/libexec:/usr/local +/bin:/usr/local/sbin:.: No such file or directory root@ns#


What gives? I'm starting to feel like there is some voodoo going on with this box that I don't completely grok! Do I have to somehow invoke the netscaler shell first,before I do anything else?

This is the contents of a directory called "/netscaler" that has a bunch of commands and scripts in it, that I can't seem to make heads or tails of. Most of them are binaries (not scripts) so I can't even "less" them to see what they contain. weird!

[Corion]: marioroy: Oh, that's always cool, having API-compatible modules. This makes testing and comparing things much easier
[marioroy]: IPC in MCE::Shared can handle 400k (sends) per second. That's seems a lot for being a pure-Perl module. After making the release, will come back and post a solution for a node by a fellow wanting faster logging.
[Corion]: While working on WWW::Mechanize:: Chrome, I had the suspicion that AnyEvent was doing something wrong, but I was able to swap it out for Mojolicious and the error persisted.
[Corion]: Of course, the error was in my own code ;)
[marioroy]: Corion, start and start_child in MCE::Hobo::Manager return a MCE::Hobo object, whereas P::FM returns the PID. I can have it return the PID though. I tried Hobo::Manager with several P::FM modules, just changed P::FM to MCE::Hobo::Manager and it works.
