UNIX for Dummies Questions & Answers

Hi

Is there a better alternative to sed command..

or any command as an alternate to sed.

Thanks!!

Perl. It is not an alternative but works similar to sed and much more.

can u telll how the perl command replicates the funtionality of sed..

I mean the syntax

thanks!

I'm guessing:
You do not understand regular expressions, so a lot of sed examples do not make sense.
try this to get started understanding sed -
sed, a stream editor

There is a section on learning about regular expressions. perl uses regular expressions as well. so does awk. Along with grep (uses regex as well) these utilities are probably the most commonly used tools on unix systems. So learning a little bit about regex ( regular expresssions) is very important.
