Re: Has anyone seen perl losing arguments?

in reply to Has anyone seen perl losing arguments?

mmmh... this line...

system(" \"$now_string\"");

probably I'm not understanding the question but...

1-Where is the "verb" for this line? No action here.

2-Why do you need to put the first arg to the subordinate perl script inside ""?

3-... And what args do you expect to be passed to the perl script called by the main script?

I suggest you to rewrite the system line avoiding to be ambiguous, like this:

system ("VERB", "ARG1", "ARG2", ...); i.e. adjust to your needs and try:

system ("perl", "", "\"$now_string"\"");

If you can, avoid also to call \"ARG1\". Wrap ARG in "" directly inside

    Invoking this way relies on the association of perl with .pl, and has worked on all the other flavours of Windows I have used (I had left that call as it was for years, because up until now, it has worked - and if it ain't broke, don't fix it). $now_string is wrapped in quotes because it has a format like "Tue Sep 20 2011 A". Failure to wrap it in quotes would have that misinterpreted as 5 arguments.

[davido]: sorry, typed that before you asked me to disable proc
[davido]: but you stumped me; don't know how to disable proc.
[tye]: I don't know if you can just dismount, but I thought so.
[davido]: yeah, umount -f isn't powerful enough.
[tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
davido needs to close laptop to board flight home from yapc.
[davido]: I'll look into it in a few hours probably.
[davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
[oiskuu]: tye, you were right: loginuid/sessionid are part of task struct if compiled with AUDITSYSCALL. I have some doubts if you should actually depend on that feature.
