SWI Prolog change working directory/get current working directory?

Question

in SWI Prolog terminal how do I view the current working directory and change the current working directory?

I found:

working_directory(CWD, CWD)

but I dont think its what I need

Why do you not think it's what you need? – C. M. Sperberg-McQueen Sep 23 '12 at 21:15 — C. M. Sperberg-McQueen, Sep 23 '12 at 21:15

To get the current working directory use working_directory(CWD, CWD).

To change the current working directory use working_directory(_, NewCWD).

Check here to see the manual entry for this predicate.

Tab completion is very handy in case directory names in the path contain space e.g. `working_directory(_, '/home/research/Artificial Intelligence/prolog').` – Imran Ali Aug 18 '18 at 08:32
If using `working_directory/2` on Windows and the change will change both the drive and directory as opposed to same drive different directory, then you need to also call `working_directory/2` a second time with just the drive letter to change drives. e.g. You are on `C:\Users\Foo` and need to change to `D:\foo\bar` then you will need to use `working_directory/2` again just with the drive letter. `working_directory(_,"D:/")`. – Guy Coder Jan 11 '20 at 13:14

very easy just open prolog on terminal and write working_directory(CWD,'NewPath').

Ex: working_directory(CWD,'/home/user/prologExerc').

To view the current directory use : pwd.

And to change it use : working_directory(CWD,'path_or_location').

Example : working_directory(CWD,'C:/Users/Student/Destop').

Remember to change the direction of slashes in the path name.
