print out result from data file
i got a data file which contains all the pid,ppid,user,command,pcpu,start_time,status. I wanted to display out the pcpu which is greater than 0.

i uses awk'{if($5 > 0){print}}' filename.txt but is printing out result which not i wanted. Is there any way which i can print out those pcpu which is greater than 0?

Both of them should work

Code:
awk '{if($5 > 0){print}}' file
awk '$5 > 0 {print}' file

Could you please put some sample data of your file.

Some CMD column values contain spaces so for Awk (with default FS) %CPU is not always $5,
therefore as long as START and STAT values don't contain spaces $(NF-2)
(the number of fields of the crrent record - 2) will work Smilie
