Re: weird ksh '~' substitution - ksh bug?

What is even more weird: $ echo ~/stuff ~/stuff ^^^ here it is not even substituted. $ echo ~/stuff /home/daniell/stuff ^^^ whereas here it is. I suspect this is not a feature? Tilde expansion is tricky stuff. If you read how it is defined (man ksh), it says: The characters following the tilde, up to the first `/', if any, are assumed to be a login name. ... If the login name is not found in the password file or if any quoting or parameter substitution occurs in the login name, no substitution is performed. I think that explains your testcases. -Otto Daniel -- LIVAI Daniel PGP key ID = 0x83B63A8F Key fingerprint = DBEC C66B A47A DFA2 792D 650C C69B BE4C 83B6 3A8F

I systematically beleive that there is nothing more to read in ksh's man page. And I am always wrong...

Rather, the lack of a leading / is causing it to be interpreted as a relative path, and you are already working in /home/daniell/. As for your actual question, I'll wait for some of the more experienced OpenBSDers to come along with an answer and go back to lurking the list. :)
