In Linux . is used to refer to the current directory, but I need to know instead using pwd what is the current directory via ..
I tried echo $(.) andecho . but doesn't work... any solution to get the same output as pwd but using .?

`pwd` == `.`, it even expands `~` to a fully qualified path, what is your actual question? This is an [X - Y Problem](http://meta.stackexchange.com/questions/66377/what-is-the-xy-problem) as stated. – May 07 '15 at 17:23

Doing `echo $(pwd)` works fine, but a requiriment client is not use pwd, I need to use `.` to get the actual dir, but `echo $(.)` doesn't work. My question is how can i do an echo to get the value of `.`? – PlainOldProgrammer May 07 '15 at 17:26

you use `echo \`pwd\``, you need to explain the requirement to use `.` it makes no sense technically or otherwise. `.` is just a short cut in the shell to `pwd` – May 07 '15 at 17:26
