vi is a text editor that is comparable to Vi. It can be used to edit all kinds of plain text. It is especially useful

for editing programs. While running vi, a lot of help can be obtained from the on-line help system, with the

:help command.

Usage

vi [options] [file ...]

Caveats

/tmp and its contents are the only files and directories that the SuperUser account has permission to

modify. When accessing files you must specify the complete path name (for example: vi

/tmp/FileName.txt). After seven days without modification, files in this directory are removed.

Options

The options may be given in any order, before or after filenames. Options without an argument can be

combined after a single dash.

Table 2-6 vi Options

Options Descriptions

+[num]

For the first file the cursor will be positioned on line num. If num is

missing, the cursor will be positioned on the last line.

+/{pat}

For the first file the cursor will be positioned on the first occurrence of

{pat}. See “:help search-pattern” for the available search patterns.

-h

Give a bit of help about the command line arguments and options.

After this, Vi exits.

-m

Modifying files is disabled. Resets the write option, so that writing

files is not possible.

-n

No swap file will be used. Recovery after a crash will be impossible.

Handy if you want to edit a file on a very slow medium (e.g. floppy).

Can also be done with :set uc=0.Can be undone with :set uc=200.

-R

Read-only mode. The read-only option will be set. You can still edit

the buffer, but will be prevented from accidently overwriting a file. If

you do want to overwrite a file, add an exclamation mark to the Ex

command, as in :w!. The -R option also implies the -n option (see

below). The read-only option can be reset with :set noro. See :help

‘read-only’.

-r {file}

Recovery mode. The swap file is used to recover a crashed editing

session. The swap file is a file with the same filename as the text file

with .swp appended. See :help recovery.
