Hi,
Is it possible to use a commando in Perl that will wait for example 50
seconds an then will continue ?
Thanks in advance

take a look at the sleep command
sleep EXPR
sleep Causes the script to sleep for EXPR seconds, or forever if no
EXPR. May be interrupted if the process receives a signal such
as `SIGALRM'. Returns the number of seconds actually slept. You
probably cannot mix `alarm' and `sleep' calls, because `sleep'
is often implemented using `alarm'.
On some older systems, it may sleep up to a full second less
than what you requested, depending on how it counts seconds.
Most modern systems always sleep the full amount. They may
appear to sleep longer than that, however, because your process
might not be scheduled right away in a busy multitasking system.
For delays of finer granularity than one second, you may use
Perl's `syscall' interface to access setitimer(2) if your system
supports it, or else see the select entry elsewhere in this
document above. The Time::HiRes module from CPAN may also help.
See also the POSIX module's `sigpause' function.
hope this helps
Ron
