Exploring Expect

About File Names

Both the exp_internal and log_file commands accept filename arguments that begin with a tilde (”~“). The tilde is interpreted as meaning “home directory” exactly the way it is defined by the C-shell. For example:

exp_internal -f ~fred/debuglog 0

This command saves diagnostic information to the file debuglog in fred’s home directory.

No other interpretation is given to the file name. If you include a wildcard such as a "*“, the file will be created with that name, exactly as you have specified. If you want wildcards expanded, use the glob command.
