NR awk problem on Ubuntu

Code:
awk 'NR> 92239 && NR<= 92279' /usr/appplications/access.log

is there a reason why the above command isn't working on kubuntu?

when i run it, i get nothing back. just the prompt. i should see the lines

OS:
Code:
3.8.0-19-generic #30-Ubuntu SMP

and yes, there are over 92279 lines in the log. i'm befuddled. any help here is appreciated.

Seems good to me. Did you try parentheses around the inequatons?

not sure how or where to put the parentheses.

Try FNR as well, you have GNU awk (gawk). The parens go around the statement to be evaluated as a boolean.

Code:
'(FNR>111 && FNR<113) {print}' filename

It won't print anything if /usr/appplications/access.log has got less than 92239 lines.

I think Ubuntu uses mawk by default, actually.

I also do not see any problem with that awk script.

For diagnostic purposes, does the following command produce the expected output?
Code:
sed -n '92240,92279p; 92279q' /usr/appplications/access.log
