crontab schedule - first thursday of every month
Instead of the first five fields, one of eight special strings may appear:
string meaning
------ -------
@reboot Run once, at startup.
@yearly Run once a year, "0 0 1 1 *".
@annually (same as @yearly)
@monthly Run once a month, "0 0 1 * *".
@weekly Run once a week, "0 0 * * 0".
@daily Run once a day, "0 0 * * *".
@midnight (same as @daily)
@hourly Run once an hour, "0 * * * *".
==================
so based on above
0 0 * 1-12 4 <<< this cron schedule will run at midnight each month on thursday? or will this trigger every thursday every month??

ipc::run::safehandles
IPC::Run::SafeHandles(3pm) User Contributed Perl Documentation IPC::Run::SafeHandles(3pm)
NAME
IPC::Run::SafeHandles - Use IPC::Run and IPC::Run3 safely
SYNOPSIS
use IPC::Run::SafeHandles;
DESCRIPTION
IPC::Run and IPC::Run3 are both very upset when you try to use them under environments where you have STDOUT and/or STDERR tied to
something else, such as under fastcgi.
The module adds safe-guarding code when you call IPC::Run or IPC::Run3 under such environment to make sure it always works.
If you intend to release your code to work under normal envionrment as well as under fastcgi, simply use this module after the "IPC"
modules are loaded in your code.
unimport
When unimport, the original IPC::Run and/or IPC::Run3 functions are restored.
