Linux tail command
I’m not sure if this can be done, but with Linux, you never know its limitations.
I’m tracking the apache logs:
\#tail -f apachelog.access-log
It gets what I want
, but I want to narrow down what it returns. This is the typical line I will get:
2011-01-28T04:20:59-07:00 SERVER03 apache: 10.0.0.1 - - [28/Jan/2011:04:20:59 +0000] "POST /a/ HTTP/1.1" 200 4461 "http://somesite.net/" "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:126.96.36.199) Gecko/20101203 Firefox/3.6.13"
Is it possible to filter my smeared content?
Sometimes, I just want to see the referring site. Sometimes I want to look at 2 or 3 other items.
You can easily perform :
tail -f apachelog.access-log | grep SERVER03
THIS WILL ONLY GIVE YOU LINES THAT CONTAIN THE STRING
