Subject: main: Error out when combining -i/--interactive and -f/--file
X-Git-Tag: v1.0.8~63
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3915af337a8c7d8366131a00acb294dd4688e436;p=thirdparty%2Fnftables.git

main: Error out when combining -i/--interactive and -f/--file

These two options are mutually exclusive, display error in that case:

 # nft -i -f test.nft
 Error: -i/--interactive and -f/--file options cannot be combined
