 |
|
Hi all,
I know this is stupid, but I just can't get it to work. I'm trying to grep through a log file and find instances where a line has one word, and not another right after it, so I'm trying:
grep 'word1' some.log | grep [^'word2']
grep 'word1' | grep -v 'word2'
grep "word1.*[^'word2']" some.log
the pattern in the million lines in the log file I want to NOT list is
word1="is word2"
and I'm looking for the pattern:
word1="any other random text"

You said you already tried:
| Code: | | grep word1 some.log | grep -v word2 |
In what way did that not work?
In grep language, ^ means the start of the line.

ah, I sorted it out...awk to the rescue 
awk '/word1/ && !/word2/' some.log | awk '!/otherwordsequence/' > textfile
That did it...I have to brush up on my grep, but this at least gave me the opportunity to brush up on awk
awk=good
