redirect output to log file

hello all,

I'm invoking the program generate-report using backticks from my perl program and redirecting the output to the log file sge-stderr.log. But when i check the process using ps command it is spawing two processes where the below code is parent process and the program generate-report as child.

Please help me out of how to redirect the output to the log file without spawing two process.

Code:
`/usr/bin/perl /opt/finance/bin/generate-report $urid 2>> /opt/finance/logs/sge-stderr.log`;

Thanks a ton,
raj

When you use the system() or the backticks in perl, the program will do a fork and exec. This will result in two processes. Why is there a restriction on the number of processes that you can create?

one process has sh -c at the beginning of /usr/bin/perl /opt/finance/bin/generate-report $urid 2>> /opt/finance/logs/sge-stderr.log at the beginning and actual program opt/finance/bin/generate-report $urid is running which is the child process of first one.

Will there be any impact or two processes are making the same program running twice... iam confused Smilie

Please explain me...
