Could anyone of you please guide me on making correct regular expression to match the exact word or character

I have some numbers like 12345780 extn 1234
1234567 x 43545
13245678 Extn 454857

 if [[ "$NUMBER" = *[x]* ]]; then
                VAR3=`echo "$NUMBER" | nawk -F "[x]*" '{print $1 $2}'`
                echo insideif
                echo $VAR3
 fi

Output is below:
inside if
12345780 etn 1234
insideif
1234567 43545
insideif
13245678 Etn 454857

Whats the value stored in variable NUMBER..?

numbers mentioned in the first message of the thread.. like 12345780 extn 1234

Then try to pattern match it with command sed . You cannot pattern match as highlighted above.
Still not very clear with your requirement. Please brief again and post the exact contents of variable NUMBERS.

echo $NUMBERS| sed '/x/!d'

Michael, Sorry for not being precise.
I was looking for whole word match using grep. Now i got it.
Below is the syntax i used..

grep "\<[Ee][Xx][tT]\>"

Thanks for all your help!
