interesting, but http://www.cyberciti.biz/faq/unix-linux-shell-find-out-posixcommand-exists-or-not/ says in the comments: "According to The Open Group Base Specifications, `command -v` is not completely portable and `type -P` is not portable either:" i'am even unsure of 'hash', because it's an builtin. And 'which' is also poorly defined: at least i can find the definition for the exitcode under ubuntu 'man which'. i'am lost - any other links for pro or contra? bye, bastian _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
