Probably posted previously, I use this all the time to find and kill a process for "APP". Simply replace "APP" with the name of the process you're looking to kill.

awk '/pattern1/ && /pattern2/ && !/pattern3/ {print}'

Rather than chain a string of greps together and pipe them to awk, use awk to do all the work. In the above example, a string would be output to stdout if it matched pattern1 AND pattern2, but NOT pattern3.

awk 'length($0)!=12 {print}' your_file_name

Alternatively, print all the lines that are a certain length:

awk 'length($0)==12 {print}' your_file_name
lspci | grep Ether | awk '{ VAR=$1; split(VAR,ARR,"."); count[ARR[1]]++; LINE=$0; split(LINE,LINEARR,":"); LINECOUNT[ARR[1]]=LINEARR[3]; } END { for(i in count) { printf("PCI address: %s\nPorts: %d\nCard Type: %s\n", i, count[i], LINECOUNT[i]) } }'
echo "SHOW PROCESSLIST\G" | mysql -u root -p | grep "Info:" | awk -F":" '{count[$NF]++}END{for(i in count){printf("%d: %s\n", count[i], i)}}' | sort -n
awk '{count[length]++}END{for(i in count){printf("%d: %d\n", count[i], i)}}'
ps awwwux | grep httpd | grep -v grep | awk '{mem = $6; tot = $6 + tot; total++} END{printf("Total procs: %d\nAvg Size: %d KB\nTotal Mem Used: %f GB\n", total, mem / total, tot / 1024 / 1024)}'
sudo lsof | awk '{printf("%s %s %s\n", $1, $3, $NF)}' | grep -v "(" | sort -k 4 | gawk '$NF==prv{ct++;next} {printf("%d %s\n",ct,$0);ct=1;prv=$NF}' | uniq | sort -nr

Kill all processes with foo in them. Similar to pkill but more complete and also works when there is no pkill command.

Works on almost every Linux/Unix platform I have tried.

diff -q dir1/ dir2/ | grep differ | awk '{ print "vimdiff " $2 " " $4 }'

We use this to quickly highlight differences and provide a quick way to cut and paste the command to view the files using the marvellous vimdiff

ps -auwx|egrep hunger|grep -v grep| awk '{print "kill -9",$1}' > ~/fu.bar
wget -O - http://www.commandlinefu.com/commands/browse/rss 2>/dev/null | awk '/\s*<title/ {z=match($0, /CDATA\[([^\]]*)\]/, b);print b[1]} /\s*<description/ {c=match($0, /code>(.*)<\/code>/, d);print d[1]"\n"} '
git log master | awk '/commit/ {id=$2} /\s+\w+/ {print id, $0}'

Useful when quickly looking for a commit id from a branch to use with git cherry-pick.

tail -10000 access_log | awk '{print $1}' | sort | uniq -c | sort -n | tail

This uses awk to grab the IP address from each request and then sorts and summarises the top 10.
