Glad you didn't... Because otherwise you would be the one to blame for the problem. $0 could easily NOT have any path, just a script name. > But anyway, as you can see ${0} always exists.

If you want to obtain a full name of a running script, you'd need something like this: XXX="$(cygpath -au "$0")" SCRIPT_NAME="$(readlink -fn "${XXX:-$0}")" This is almost platform-independent, even. To the extent of readlink -f option support. -- WBR, Andrey Repin (anrdae...@yandex.ru) 17.09.2013, <00:19> Sorry for my terrible english... -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
