let say, I have table in the imagewhich is basically "qstat" of HPC jobs:
I like to print out columns 2 and 6 which match NDS==1 and TSK==1
I am using command:
qstat -a |grep ' $4=="1" $5=="1" ' |awk 'print $2, $6'
It shows no output with no error message. What I am missing?
Thanks,

Please, don't post images of text. It makes it very difficult to test whether solutions actually work.

You are confusing grep and awk slightly.
With grep ' $4=="1" $5=="1" ', grep would interpret $4=="1" $5=="1" as a regular expression. This expression would try to match a 4 occuring after the end of the line ($), which can never happen.
Instead:
qstat -a | awk '$4 == "1" && $5 == "1" print $2, $6 '
If you want the header as well:
qstat -a | awk 'NR == 1 || ($4 == "1" && $5 == "1") print $2, $6 '

Thanks. Why NR == 1 ?

@Akand That would trigger theprintstatement for the header line as well (the first input line which hasNRequal to 1), so that you get the column names. This is what I meant by "if you want the header as well".
