Grep/ionice

Oct 31, 2009

I am trying to run a script that will locate the process number and will change the iowait priority

This will display the process number :

ps -ef |grep rsync|grep -v grep | awk '{print $2}'

ionice runs like this:

ionice -c3 -p <process number>

Any way to combine these to change iowait priority of a process?

Having Trouble With Grep

Feb 6, 2007

Having some trouble using grep and hoped someone might be able to help.

Running the following command to try and scan for an IP address match across a period of time in our access_logs:

grep '04/Feb/2007:21:*:*' /var/www/vhosts/*/statistics/logs/access_log.processed | grep
'216.2*.*.*'

This is returning all kinds of IP address results such as: 58.216.50.2 Can you suggest how I can tweak the grep command to search for the right IP addresses?

I want to scan precisely for IP addresses starting 216.2*.

We've been given the following information about spam, and want to track the source of it
down:

216.2x.x.x - email spam

So any ideas how I can scan these logfiles more precisely for the IP address I need?

Netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1

Feb 1, 2007

What does this string do? I copy and paste it into my SSH Shell and i get ip addresses and numbers next to them.

Each number means one connection?

netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1
