I have a requirement where i need to integrate shell command to perl. I am aware how to do it.

But, i need to run this shell cmd (which is snmp walk for 20 mibs repeatedly) at the beginning of the script and stop only after all other executions (say, testcases) are over

to be more precise, run this shell cmd at the background and stop when the script finishes its whole execution

.

I was thinking 2 options. One is use a subroutine and add this shell cmd inside and call after each testcases. There is a problem with this. The shell will start and stop after each call, which i dont want

.

Do you have any suggestions
