"grep string | grep string" with awk without pipe [duplicate]

Question

This question already has answers here:

How to run grep with multiple AND patterns? (11 answers)

Closed 4 years ago.

Is there a way to do:

output | grep "string1" | grep "string2" 

BUT with awk, WITHOUT PIPE?

Something like:

output | awk '/string1/ | /string2/ {print $XY}'

Result should be subset of matches, if tha makes sense.

• steeldriver: Have a look at the accepted answer here: grep with logic operators
• Archemar: just a | missing : awk '/string1/ || /string2/ {print $XY}'
• Stephen Kitt: @Archemar that’s not quite the same though: || will match any line with either "string1" or "string2", whereas the greps only match lines with both (so && in AWK).
• Archemar: my bad, I read too quickly once again ...
• RiddleMeThis: its supposed to mean column number e.g. 0,ドル 1ドル etc.

Answer 1

The default action with awk is to print, so the equivalent of

output | grep string1 | grep string2

is

output | awk '/string1/ && /string2/'

e.g.

$ cat tst
foo
bar
foobar
barfoo
foothisbarbaz
otherstuff
$ cat tst | awk '/foo/ && /bar/'
foobar
barfoo
foothisbarbaz

• RiddleMeThis: Accepting this answer because of the extra example/ proof
• Ed Morton: That is the equivalent of the pipeline the OP provided but if the OP actually wants to match 2 strings instead of 2 regexps then it'd be awk 'index(0,ドル"string1") && index(0,ドル"string2")

Answer 2

If you want awk to find lines that match both string1 and string2, in any order, use &&:

 output | awk '/string1/ && /string2/ {print $XY}'

If you want to match either string1 or string2 (or both), use ||:

 output | awk '/string1/ || /string2/ {print $XY}'

• RiddleMeThis: Just to note, for anyone who stumbles upon this, what I exactly did was: ps aux | awk ... to keep awk from showing in the result I had to do awk /[s]tring/. Its the same trick used for grep.
• Quasímodo: I think the {print $XY} thing is something like a placeholder that the OP thought would be useful/necessary. I believe it is better out of the answer since it doesn't make much sense.
• terdon: @Quasímodo it makes perfect sense: it is a placeholder for "print field number N" and including it shows what the correct syntax would be, so it can easily be adapted by future users.
