What happened in linux bash when I use & ldquo; Cd // & rdquo;


I find an interesting thing about linux bash. After I typed cd // in linux bash.Guess what happend? The directory became //,then I pwd,the directory is //. But I don't know what happend to the bash.

That's what should have happened.

When you did cd //, the system changed your directory to /. So pwd will tell you (correctly) that you are in //. (Refer to the answer linked in the comments to understand why multiple slashes are the same as a single slash).

If you do an ls after your cd // command you'll see a lot of folders that are mounted on /.

Nothing 'happened to the bash'.

If you do a cd , it will take you back to your more famliar $home.
