Examples of setting vi options permanently

1. To set a number of options place the set commands in the file .exrc.

   set ic
   set number
   set sh=/usr/local/bin/Tcsh
   set wm=5

This sets vi to:

   - ignore the case of characters in searches
   - display line numbers
   - use the TC shell to execute UNIX commands
   - wrap text five characters from the right edge
     of the screen

2. Options can also be set using the environment variable EXINIT.

   setenv EXINIT 'set ic number sh=/usr/local/bin/Tcsh wm=5'

For the C and TC shell user, this sets the same options as in the example above.

If there is a .exrc file owned by you in your home directory or the current directory, vi will take its option values from this and not from the EXINIT environment variable.
