egrep for only words(exact match)

msgforsunil · 04-14-2010, 04:38 AM

Hi All,

I have the below file content
<sunilkumar@test5>more test.ksh
movie work
a or b
clear

Query1: For the below command, is there anyway, I can see the strings not found as part of search. For eg. the command should output "and" is not found

Query 2: For the below command, is there any way, I can list only "a or b" and not "movie work"; I meant exact word search. If yes, how do I do that?

<sunilkumar@test5>egrep -i "or|and" test.ksh
movie work
a or b

For your second query add word boundaries to your search

Code:

egrep --color -i "\bor|and\b" test.ksh

for more info look in to the man pages

Code:

man egrep
