Hi,

I need one help for choosing best option among sed, perl and awk.
I need to search and replace thousand files for a text and need to replace it. I am in confusion for choosing the option for best results.

Because by using sed option its taking too much time for searching and replacing text in all thousand files. And redirecting the modified files to the same directory.

At present i am using sed for the above.But its taking 2 hrs to replace and redirect the modified files .

Can anyone suggest for choosing best among sed ,perl and awk?
