vi(1) OSS Shell and Utilities Reference Manual
Keeping a Customized Change
The editing environment defaults to certain configuration options. When an editing session is
initiated, vi attempts to read the EXINIT environment variable. If it exists, the editor uses the
values defined in EXINIT, otherwise the values set in $HOME/.exrc are used. If $HOME/.exrc
does not exist, the default values are used.
The vi Character Sets
The collation sequence, as defined by the value of the LC_COLLATE environment variable,
defines the alphanumeric set used by your system. This table affects the performance of vi mac-
ros and subcommands.
The vi editor uses the collation sequence to distinguish between a small word and a big word. A
small word is bounded by letters or numbers as defined in the collation table. For example, isn’t
is two small words. The ’ (apostrophe) is not a number or an alphabetic character, and it bounds
both the small word t and the small word isn. A big word is bounded by spaces, tabs, or newline
indicators. For example, accommodate is a big word. For more information, see the section
Moving to Words.
SUBCOMMANDS
Subcommand Syntax
[named_buffer][operator][number] argument
Surrounding brackets indicate optional items.
[named_buffer]
A temporary text storage area.
[operator]
Specifies the subcommand or action; instructs the vi editor.
[number] A whole decimal value that specifies either the extent of the action or a line address.
The vi editor interprets this number in one of the following ways:
1. Go to line number:
5G
10z<Return>
2. Go forward number columns.
25<Space>
3. Scroll number of lines:
10<Ctrl-d>
10<Ctrl-u>
4. Delete number lines:
