I have a file like this.
No. State Query Times User Processed Syslog
the final number before .syslog is the process id.
for eg: in the above if you take 7th one 8563 is the PID.
Now what i want to achieve is if the user name is null in the users column all
i tried the below command for $4 > 200000s but it's not printing correctly.
cat procs.txt|awk '{if( $4 > 200000s ) print $4,$7 }

awk ' { tm=$4; sub("s","",tm); if( tm > 20000 ) print } ' file
Anbu, it's showing me all the values not above 200000
crypto $ awk ' { tm=$4; sub("s","",tm); if( tm > 200000 ) print } ' procs.txt

Anbu, it's throwing me error.
crypto $ awk ' { tm=$4; sub("s","",tm); if( tm > 200000 ) print } 'procs.txt
Also Please let me know how to print if the users column is null.
Your first line of the file causes the problem
No. State Query Times User Processed Syslog
awk ' NR > 1 { tm=$4; sub("s","",tm); if( tm > 200000 ) print } 'procs.txt
If you are sure that only the user field contains null then try this
awk ' NF < 7 ' file
or you try this
awk ' $0 !~ "[0-9]+s [^ ]+ [0-9]+" ' file
2nd one is also not working the same output.
crypto $ awk ' $0 !~ "[0-9]+s [^ ]+ [0-9]+" ' procs.txt
otherwise if i print $5 in my file it shows below like this.
crypto $ awk '{print$5}' procs.txt
as for those who doesn't have users name next column is considered as 5th column. in this situation.so can we print the single digit rows which is considered to be no users.
And first one no luck its not printing.

I made modification in the above code. Its NF < 7 and not < 6
Anbu i got the list of processes in the below format.
5293
now how can i insert this process id's in kill -9 command.
Anbu,
Your second one is working perfect. But i need some help for 1st one that is if the $4 > 200000. it's not working for me.

Send all the process ids to a temp file and kill process ids like
kill -9 $(<temp)
