I've used smbmount to mount a windows file system into my /home/myname/mnt directory. The windows directory has a subdirectory named "Legal Documents" in it. I can see everything inside the mounted directory including the Legal Documents directory, but because ( I think ) the directory name has a space in it, I haven't been able to change into that subdirectory. From inside the mounted directory, I do a "cd Legal Documents" and I get a message "No such file or directory". I can't rename the directory as it's in use by a number of other people. Without renaming it and doing away with the space, how can I get into this subdirectory ???

Try:
cd Lega*

or:
cd "Legal Documents"

Or try tab completion, that usuallly gets it for me.

Yes that's true. Tab completion usually just escapes the space and is the same as typing:
cd Legal\ Documents

Thanks for your suggestions guys, they all worked. One more I tried that I hadn't thought of before now is - cd "Legal Documents" with the quotation marks around the directory name - that also worked.
