perldoc -f "system"

or you could use backticks as in:

Hi,
I am facing an issue with the perl system command
The relevant lines of code are the following:
chdir "$util";
my @args = ("ldapmodify", "-D \"cn=$bdn\"", "-w $bp", "-h $svr", "-f \"$ldif\"", "-c",
&q
works good now:
my $file_to_print = ( `ls -1c /test/*log | tail -1 `);
print "file_to_print: $file_to_print";
open (FILE, "< /test/$file_to_print") or die "Could not open
file_to_print $: $!";
although the third line is not opening the file. It prints out good
but but I

Since you didn't chomp() it, and since you didn't need to add a
newline when you printed it, it seems that $file_

Hi All,
I've never tried something like this before, so
my apologies if it's "easy"
We all know about the system command:
my $program = "some_script.pl";
system("perl",$program);
This would execute the program some_script.pl
on the current host.

I would run system commands with the backticks. That tells Perl to run the command
and place the contents in the variable you defined.
System OTOH returns if the command completed successfully (at least I believe that's
what happened here).

I want to use system() (or `command`) to run an external command from
my Perl script. However, if the external command takes more than 30
seconds (for example) to run, I want to kill it, and move on with the
rest of my Perl script. How do I do this?
