12 This manual page documents briefly the lnstat command.
13
14 lnstat is a generalized and more feature-complete replacement for the
15 old rtstat program. In addition to routing cache statistics, it sup‐
16 ports any kind of statistics the linux kernel exports via a file in
17 /proc/net/stat/.
18
20 These programs follow the usual GNU command line syntax, with long
21 options starting with two dashes (`-'). lnstat supports the following
22 options.
