Hi bastian, If you are just typing false on openwrt shell, it uses false in the built in shell. root@OpenWrt:~# type false false is a shell builtin root@OpenWrt:~# false --help root@OpenWrt:~# echo $? 1 root@OpenWrt:~# There is no problem with ash built in false. The problem is busybox false applet. To invoke busybox false, either call '/bin/false' or '/bin/busybox false' root@OpenWrt:~# /bin/false --help ; echo $? BusyBox v1.22.1 (2014-08-28 15:20:07 WIB) multi-call binary. Usage: false Return an exit code of FALSE (1) 0 root@OpenWrt:~# busybox false --help ; echo $? BusyBox v1.22.1 (2014-08-28 15:20:07 WIB) multi-call binary. Usage: false Return an exit code of FALSE (1) 0 That's the unexpected behavior from busybox false applet. _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
