Hi, Scrutinizer

that's a typing mistake on the post sorry

I erased the "END" and it still has syntax error

Code:
awk: browser.awk:1: /Mozilla/ {print $0} > /home/lunaticdawn/log/mozilla.txt
awk: browser.awk:1: /Mozilla/ {print $0} ^ syntax error
awk: browser.awk:1: /Mozilla/ {print $0} > /home/lunaticdawn/log/mozilla.txt
awk: browser.awk:1: /Mozilla/ {print $0} > /home/lunaticdawn/log/mozilla^ sysntax error

Ow yes you should put double quotes around the path/filename. In some awks you need to put it in a variable first and print to the variable...

Thanks Scrutinizer

as your advice, solved a syntax error, but still got a syntax error on the " > "

I tried a few times, like ">>", insert { }, still cannot solve it

the print function is work, but the output to another file part drive me crazy...

Try this:
Code:
awk '
  /Mozilla/{print>moz}
  /IE/     {print>ie} 
  /chrome/ {print>chr}
' moz=/home/lunaticdawn/log/mozilla.txt ie=/home/lunaticdawn/log/IE.txt chr=/home/lunaticdawn/log/chrome.txt infile

Perhaps we could make the script more universal.. Could you post part of the Tomcat log?

Thanks Scrutinizer

/Mozilla/{print>moz}
this one exactly can do what I want!! just a simple {print>xxx}Smilie!!!

awk -f browser.awk server.log
browser.awk
Code:
moz = /home/lunaticdawn/moz,txt
/Mozilla/ {print>moz}

it works now!!! Thanks so much!!!


this is part of the log
Code:
"192.168.0.1" "NULL-AUTH-USER" "21/Mar/2012:08:30:07 +0000" "HTTP/1.1" "Mozilla/4.0" 200

at first I tried using IFS and case to do, but I dont know how to print the hold line that match the case, so I try to use awk now, thanks Scrutinizer.

That's a bit short. Assuming that the browser is always in the before last column, you could try if this works:
Code:
awk -F'["/]' '{f=dir "/" $(NF-2) ".txt";print>f}' dir=/home/lunaticdawn/log infile

This would use the name of the browser from the log and write to a file with a corresponding name...
