How to quickly show Nth line from the file
Hi all,

See 2717298 th line.

Code:

nodesave

NODESAVE(8)						   Linux System Managers Manual 					       NODESAVE(8)

NAME

       nodesave - Saves NET/ROM routing information

SYNOPSIS

       nodesave [-p path] [-v] [filename]

DESCRIPTION

       Nodesave  saves	the contents of the /proc filesystem entries for the NET/ROM routing tables. The output of the program is in the form of a
       Bourne shell script that calls nrparms(8) to recreate the NET/ROM routing information. If no filename is given on  the  command	line,  the
       program writes the script to stdout.

       Typically  nodesave  would  be  used  when  taking  a system off-air so that the NET/ROM routing may be quickly restored when the system is
       brought back on-line.

OPTIONS

       -p path	 Set the path to the nrparms binary. This only affects the output of the program. Default is /usr/sbin.

       -v	 Display the version.

FILES

       /proc/net/nr_neigh
       /proc/net/nr_nodes

SEE ALSO

       netrom(4), netromd(8), nrparms(8).
