How to remove filename from output file?
Hello,
I am trying to print searched multiple keywords in multiple files.
It is almost okay with the code but the code puts filename in front of each line.
How may I get rid of it?

Code:
-grep -A1 'word1' *.txt | grep -A1 'word2' | grep -A1 'word3'

I expect:
Quote:
word1 word2 word3
how are you?
word1 word2 word3
I am fine
word1 word2 word3
Where've you been?
Real outcome:
Quote:
file1.txt:word1 word2 word3
how are you?
--
file222.txt:word1 word2 word3
I am fine
--
file342.txt:word1 word2 word3
Where've you been?
How may I remove file*** expression with grep?

Thanks in advance
Boris

add -h to the grep.
man grep

I'd be surprised if that "real output" is the pipe's real output, as the second grep would eliminate all lines that don't have word2 in them, and the third equivalently. I'd expect an empty result unless word(1|2|3) are sub- or supersets of each other, or all three occur in one line.

Hello Rudic,
You are right, but the problem was about filename so I am gonna update the main thread now.

Thanks
