issue in calling perl script multiple times from another perl script	Can't Post

hi

My code look like this
@list = qw {one two};

foreach my $name (@list)
{
system("perl run.pl $name");
}

Issue is run.pl is not running completely. It runs and appeared tobe finished in a second. Both time it looks like running for a while and exiting. If I run the script manully it runs properly.
How to call the script second time only after the first one is completed.?

If you are using

Code

system("perl run.pl $name");

your program is supposed to wait for the execution of run.pl before going to the next step in the loop. With the 'system' instruction, the parent process waits for the child process to complete before proceeding.

Maybe the problem is in the run.pl program.

make sure the directory is included to the perl script and that you're useing the array @ARGV to get the name you supplied as the argument..

Code

system "perl /home/blah/cgi-bin/run.pl $name"; 
 
or 
 
system "perl c:/folder/to/file/run.pl $name";
