In the future please send discussion questions concerning the
coreutils to the coreutils mailing list instead of the bug-coreutils.
The bug-coreutils mailing list is for bug reports only and every email
message opens up a bug in the bug tracking system. I am closing this
bug report but discussion may continue. Thanks.
A good place for general help questions is help-gnu-utils <at> gnu.org.

I would use sed for this. Don't print by default (-n) and then print
the 3rd line.
$ printf "1234567890\n1234567890\n1234567890\n" | sed -n 3p
If you want specific characters then you can delete the unwanted
ones. This is a contrived example:
$ printf "1234567890\n1234567890\n1234567890\n" | sed -n '3{s/^..\(..\).*/\1/;p;}'
Or you can chain commands together. Print only the third line to a
command that pulls apart fields.
$ printf "11 12 13\n21 22 23\n31 32 33\n" | awk 'NR==3{print$2}'
32
$ printf "11 12 13\n21 22 23\n31 32 33\n" | awk 'NR==3{print $2, $3}'

In the future please do not include such useless and annoying
disclaimers in your email. The terms are incompatible with a free
software mailing list. If you cannot avoid this then please use one
of the many free email providers on the network.

How can we extract few characters from second or third line of a text
file using cut command of Linux OS?
For example: to get 7-10 characters from 3rd line of a text file is
required, what can be the command?
