Grep multiple exact match, do not display lines
Hi,

Need help to grep the following from a file x. I just want to grep exact match not lines and not partial word.

Code:
CONFSUCCESS
CONFFAIL
CONFPARTIALSUCCESS

Code:
>cat x
xczxczxczc zczczcxx CONFSUCCESS czczczcczc
czxxczxzxczcczc CONFFAIL xczxczcxcczczc
zczczczcz CONFPARTIALSUCCESS czczxcxzc

i tried this

Code:
grep -w "CONFSUCCESS\|CONFFAIL\|CONFPARTIALSUCCESS" x

also this, getting only matching words not the whole word

Code:
grep -o "CONF*" x
CONF
CONFF
CONF

Want result as below

Code:
CONFSUCCESS
CONFFAIL
CONFPARTIALSUCCESS

Thanks

Try for printing words

Code:
$ grep -o 'CONFSUCCESS\|CONFFAIL\|CONFPARTIALSUCCESS' file

OR

Code:
$ egrep -wo 'CONFSUCCESS|CONFFAIL|CONFPARTIALSUCCESS' file

another awk approach for same.


Input is as follows.

Code:
xczxczxczc zczczcxx CONFSUCCESS czczczcczc
czxxczxzxczcczc CONFFAIL xczxczcxcczczc
zczczczcz CONFPARTIALSUCCESS czczxcxzc


Code:
awk '{for(i=0;i<=NR;i++) {for(i=1;i<=NF;i++) {if($i=="CONFSUCCESS" || $i=="CONFFAIL" || $i =="CONFPARTIALSUCCESS")  print $i}}}' file_name

Output will be as follows.

Code:
CONFSUCCESS
CONFFAIL
CONFPARTIALSUCCESS


Thanks,
