Created attachment 8251 [details] requested config file Hi. I'm using Busybox with OpenWRT. This error was present since at least may this year, likely earlier. $ echo "8.8.8.8 via 192.168.0.1 dev br-private src 192.168.0.32 uid 0"| sed -nE 's/^.*dev\s*([^\s]*)*.*$/\1/p' br-private The problem is the blank before the interface name. With GNU sed, the line functions correctly. warm wishes
Oops. Forgot i did this.. Here's another: ip rule list | sed -nE 's/^.*iif\s*([^\s]*).*lookup\s*2.*$/\1/p' | grep '\-n_' | hexdump -C 00000000 62 72 2d 6e 5f 37 33 34 20 0a |br-n_734 .| 0000000a echo '2: from all iif br-n_734 lookup 2' | sed -nE 's/^.*iif\s*([^\s]*).*lookup\s*2.*$/\1/p' | grep '\-n_' this time it spits out a space at the end.
