NR ?

[linmac]

I got script

.....
lineno=0
syscommnand | awk 'NR>$lineno && NR<$lineno-2 {print $2, $6)'
let lineno=$lineno+10
...

but the script doesn't work b'cause the $lineno in &quot;NR&quot;, how can I pass the variable to NR? or can someone give me better code b'cause I am new to awk. thanx in very advance.

Hi,
The problem here isn't NR but the fact tahee $lineno is a SHELL variable which is not being processed before getting set to awk because you have single quotes around it.
