MPE/iX Shell and Utilities Reference Manual, Vol 2

vi(1) MPE/iX Shell and Utilities vi(1)
autowrite, aw
When this option is on, the current file is automatically written out if it has been
changed since it was last written and you have run any of the following commands:
next, rewind, tag, CTRL-ˆ (Vi), and CTRL-] (Vi). Using an exclamation mark (!)
with any of these commands stops the automatic write.
The default is noautowrite.
beautify, bf
When this option is on, the editor discards all non-printing characters from text read
in from files.
The default is nobeautify.
directory, dir
The editor uses temporary files with unique names under the given directory. Any er-
ror on the temporary files is fatal.
The default is directory=/tmp.
edcompatible
When this option is on, the editor attempts to make substitute commands behave in a
way that is compatible with the ed editor. The g and c options on the substitute com-
mands are remembered and toggled by their occurrence. The r option uses the last
regular expression rather than the last substitute regular expression. Percentage mark
(%) as the entire pattern is equivalent to the previous pattern.
The default is noedcompatible.
errorbells, eb
When this option is on, vi precedes error messages with the alert character. When it
is off, the editor warns you of an error by displaying a message using a standout
mode of your terminal (such as inverse video).
The default is noerrorbells.
exrc When this option is on, Ex and Vi access any .exrc files in the current directory
during initialization. If it is off, Ex and Vi ignore such files unless the current direc-
tory is the
HOME directory.
The default is noexrc.
ignorecase, ic
When this option is on, the case of letters is ignored when matching strings and regu-
lar expressions.
The default is noignorecase.
