using egrep to get result

tvrman · #1 (**permalink**) 08-30-2008

Hi all,

Can egrep using AND OR ?, like egrep -i "title.$1" AND "category.$2" ./home....

I want to give two search criteria, the files where egrep is seaching in for example
looks like below rows.
title this is an test
category space

(command line input)
$1 script.sh this space

thanks

With egrep:

search for $var1 OR $var2:

Code:

egrep "[$var1]|[$var2]" file

search for $var1 AND $var2:

Code:

egrep "$var1.*$var2|$var2.*$var1" file

Regards

Actually the examples are wrong. But this is a duplicate of another thread; see http://www.unix.com/shell-programmin...-new-post.html

Hi Era,
thank you very much, this should be the solution? var1.*var2|var2.*var1, should this create the AND?

Yes, that checks for var1 and var2 on one and the same line, in any order.
