i can only see: line 335: [ "$channel" = "auto" -o "$channel" = "0" ] || { fixed=1 } line 528: ${fixed:+fixed-freq} which means: if channel is auto or 0, than the freq is NOT fixed, so dont insert the statement. the syntax: ${variable:+bla} means: has variable a value, than output "bla", which is the same like [ -n "$variable" ] && echo "bla" (but often used inline) for further explenation read here: http://tldp.org/LDP/abs/html/parameter-substitution.html bye, bastian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
