Wide is turning on by option "-W" and show additional information about routes (only for IPv4 family, as I understand route.c) - MTU and the full interface name(limited, however, by 8 symbols). In "usual" mode Netif limited by 6 symbols, which definitly isn't enough for VLAN interfaces: === netstat -rn| head -n6 Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 217.119.16.33 UGS 0 2147187618 em0 10.1.0.0/16 10.78.77.9 UG1 0 0 vlan30 === === netstat -Wrn| head -n6 Routing tables Internet: Destination Gateway Flags Refs Use Mtu Netif Expire default 217.119.16.33 UGS 0 2147115775 1500 em0 10.1.0.0/16 10.78.77.9 UG1 0 0 1500 vlan3050 === I think, that truncating Netif is absolutely incorrect and easily confusing most FreeBSD users. So I propose: 1. Limit wid_if by getting width of longest netif name (i.e. automatically, on-the-fly) 2.1 Show full netif by default or: 2.2 Add special "truncated" symbol at the end of Netif, for example ">", like that: === Routing tables Internet: Destination Gateway Flags Refs Use Netif Expire default 217.119.16.33 UGS 0 2147187618 em0 10.1.0.0/16 10.78.77.9 UG1 0 0 vlan30> === >How-To-Repeat: >Fix: Don't know C as should, but it looks like it might be easily patch route.c >Release-Note: >Audit-Trail: >Unformatted:
