Hi

I have a situation where i have a file with values in that, Something like below.

12345
67890
35790

I have a variable "$ELEMENT" holding these values, Now i need pass these variable values in grep statement to get messages having these numbers from one file(text1.dat) and create new one(text2.dat).

Below is my grep statement in perl.

system("grep -h \"$ELEMENT\" text1.dat >> test2.dat");

I know the grep statement in not true, Because i cannot pass variable there. I am not sure how to use variable in grep in perl code.Any suggestions??

Thanks

A better way to do it would just be:

The backticks avoid the need to use the system() call

Hope this helps,

I guess the question I have is, does the perl script only do this task? Just seems grep could well do the task on its own.

Also, can't Perl do this? I don't see the need for grep.

Perl also has a grep function. Can't we simply use perl grep function?

Why did you bump a dead thread just to repeat what the last post said?
