On systems which pass the program name as an argument, such as Unix and Minix, you may also install elvis under the names "ex", "vi", "view", and "input". These extra names would normally be links to elvis; see the "ln" shell command.
When elvis is invoked as "vi", it behaves exactly as though it was invoked as "elvis". However, if you invoke elvis as "view", then the readonly option is set as though you had given it the "-R" flag. If you invoke elvis as "ex", then elvis will start up in the colon command mode instead of the visual command mode, as though you had given it the "-e" flag. If you invoke elvis as "input" or "edit", then elvis will start up in input mode, as though the "-i" flag was given.

Auto-indent mode is not quite compatible with the real vi. Among other things, 0^D and ^^D don't do what you might expect.
Long lines are displayed differently. The real vi wraps long lines onto multiple rows of the screen, but elvis scrolls sideways.

Many other people have worked to port elvis to various operating systems. To see who deserves credit, run the :version command from within elvis, or look in the system-specific section of the complete documentation.
