Let's face it, the file was a little bit generally messed up. The indention was confusing. It needed some cleanup. I know we both understand the file format.

Yes. $ strings /sbin/ifup | grep -c '\<ip\>' 42 $ strings /sbin/ifup | grep '\<ip\>' | head ip link set dev %iface% down ip link set dev %iface% up ip tunnel del %iface% /sbin/ip ip tunnel add %iface% mode %mode% remote %endpoint% [[local %local%]] [[ttl %ttl%]] ip link set %iface% up [[mtu %mtu%]] ip addr add %address%/%netmask% dev %iface% [[peer %dstaddr%]] [[ ip route add default via %gateway% ]] ip addr add %address%[[/%netmask%]] [[broadcast %broadcast%]] [[peer %pointopoint%]] [[scope %scope%]] dev %iface% label %iface% ip link set dev %iface% [[mtu %mtu%]] [[address %hwaddress%]] up $ strings /sbin/ifup | grep '\<ifconfig\>' ifconfig %iface% down Older Debian: $ strings /sbin/ifup | grep -c ifconfig 10 It uses 'ip' now.
