The command that I have prints out two of the lines whenever FW_6.0.0 is found, below is the code:

grep -oP 'FW_6.0.0, (.*)$' file

Below is the output, both has the same value of FW_6.0.0

FW_6.0.0, SUCCESS
FW_6.0.0, OK

I would like to match two words, that is FW_6.0.0 and SUCCESS that can be found on the same line so that it prints this out:

FW_6.0.0, SUCCESS and eliminates FW_6.0.0, OK

Is the order matter? –  Gnouc Jul 4 at 3:27
    
Yes FW_6.0.0 should come first. –  user3081935 Jul 4 at 3:28

try using double quotes "":

grep -oP "FW_6.0.0, SUCCESS" file

OR (Because it is a fixed string, not a pattern):

grep -oF "FW_6.0.0, SUCCESS" file

from grep man page:

-F, --fixed-strings
          Interpret  PATTERN  as  a  list  of  fixed strings, separated by
          newlines, any of which is to be matched.  (-F  is  specified  by
          POSIX.)
-P, --perl-regexp
          Interpret PATTERN as a Perl regular expression.  This is  highly
          experimental and grep -P may warn of unimplemented features.

I don't see the regex there, let alone the PCRE. So why grep -P instead of grep -F? –  Hauke Laging Jul 4 at 3:37

If you want to use awk:

awk '/FW_6\.0\.0/ && /SUCCESS/' file

you have to escape the dots, otherwise it matches FW_6f0f0 also. –  Avinash Raj Jul 4 at 6:00
    
@AvinashRaj Good point: thank you. Updated. –  jasonwryan Jul 4 at 6:06

Try:

grep -o 'FW_6.0.0.*SUCCESS' file

We don't need -P option here.

Through sed,

$ sed -n '/FW_6\.0\.0.*SUCCESS/p' file
FW_6.0.0, SUCCESS
