After rechecking getcwd on HP-UX also returns the physical path. I tested on that machine only with pwd... Which is aliased to echo $cwd - damn uni acounts... Maybe I have just a wrong view on that issue and softlinks have never been worked that way. > Look at getcwd_logical() in pwd.c Aha - but that does mean trusting $PWD. -- B.Walter COSMO-Project http://www.cosmo-project.de ticso@cicely.de Usergroup info@cosmo-project.de To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
