Decrease buffer size
Hi,
I am using the below command to get the output in a file called "Logs.txt"
HTML Code:
 tail -f filename | egrep -i "cpu | hung " >> Logs.txt
The problem is the Logs.txt file gets updated only after the buffer is 8Kb, but i want to update the file immediately and not wait for the buffer to get 8kb.
Is there a way to decrease the buffer size.

Thanks

If your version of egrep supports it, try --line-buffered

Is there any other option --line-buffered is not supported.

The problem isn't the buffer size per se, but the fact that it's buffering at all... Maybe try an alternate command:

Code:
tail -f filename | nawk '/[cC][pP][uU] | [hH][uU][nN][gG]/'
