Processes

I have a file like this.

No. State Query Times User Processed Syslog
1 ready idle 973s 0 /Application/ugsvols/bldata01/logs/imanscript1562.syslog
2 ready idle 803s 83997 13 /Application/ugsvols/bldata01/logs/imanscript1542.syslog
3 ready idle 2954s 106641 5 /Application/ugsvols/bldata01/logs/imanscript24717.syslog
4 ready idle 5674s 82692 15 /Application/ugsvols/bldata01/logs/imanscript16618.syslog
5 ready idle 12626s X035077 5 /Application/ugsvols/bldata01/logs/imanscript27216.syslog
6 ready idle 16088s X038493 19 /Application/ugsvols/bldata01/logs/imanscript16795.syslog
7 ready idle 19069s 105837 14 /Application/ugsvols/bldata01/logs/imanscript8563.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
the process should be killed. then it should check for all users. if the users idle time that is $4 is greater than 20000 secs it should kill those process. Please let me know how to acheive this.

i tried the below command for $4 > 200000s but it's not printing correctly.

cat procs.txt|awk '{if( $4 > 200000s ) print $4,$7 }

The error context is

awk: Quitting
The source line is 1.

Also Please let me know how to print if the users column is null.
Your first line of the file causes the problem
Code:
No. State Query Times User Processed Syslog

Code:
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
Code:
awk ' NF < 7 ' file

or you try this
Code:
awk ' $0 !~ "[0-9]+s [^ ]+ [0-9]+" ' file
