That's true. I quess that you could still take that variable away from your script, like this:

Code:

echo $(cd $(dirname $0);pwd)

Sure you can.

Well, if you absolutely positively must have the directory name in full, this should work:

Code:

 (c=$(which $0);cd ${c%${c##*/}};pwd -P)

bash or ksh.

which has no advantage over:

Code:

(cd $(dirname $0);pwd)

and is non portable (pwd -P ?)

true.

pwd -P
korn shell bash built-in.
it works on solaris.
ok then /usr/bin/pwd

what was the question again?
I think the OP may have died
