Filename completion is only available if the the environment variables EDITOR and/or VISUAL are set to either emacs, gmacs or vi. For example:
EDITOR=emacs
The value of the VISUAL variable takes precedence over the value of the EDITOR variable.
To complete a file or directory name with emacs or gmacs set press the ESC key twice.
ls -l on<ESC><ESC>line_help
If the filename is not completed enter more characters until the filename can be uniquely identified.
Directories are shown by the trailing / character.
To complete a file or directory name with vi set press the ESC key and then the \ (backward slash) key.
ls -l on<ESC>\line_help
If the filename is not completed enter more characters until the filename can be uniquely identified.
Directories are shown by the trailing / character.
To list all the possible names of files press the ESC key followed by the = key.
ls -l S<ESC>= 1) SIRS 2) Solaris
