Command: mined - MINIX editor
Syntax: mined [file]
Examples: mined /user/ast/book.3 # Edit an existing file
mined # Call editor to create a new file
ls -l | mined # Use mined as a pager to inspect
Mined is a simple screen editor. At any instant, a window of 24
lines is visible on the screen. The current position in the file is
shown by the cursor. Ordinary characters typed in are inserted at the
cursor. Control characters and keys on the numeric keypad (at the
right-hand side of the keyboard) are used to move the cursor and perform
Commands exist to move forward and backward a word, and delete
words either in front of the cursor or behind it. A word in this
context is a sequence of characters delimited on both ends by white
space (space, tab, line feed, start of file, or end of file). The
commands for deleting characters and words also work on line feeds,
making it possible to join two consecutive lines by deleting the line
feed between them.
The editor maintains one save buffer (not displayed). Commands are
present to move text from the file to the buffer, from the buffer to the
file, and to write the buffer onto a new file. If the edited text
cannot be written out due to a full disk, it may still be possible to
copy the whole text to the save buffer and then write it to a different
file on a different disk with CTRL-Q. It may also be possible to escape
from the editor with CTRL-S and remove some files.
Some of the commands prompt for arguments (file names, search
patterns, etc.). All commands that might result in loss of the file
being edited prompt to ask for confirmation.
A key (command or ordinary character) can be repeated n times by
typing ESC n key where ESC is the 'escape' key.
Forward and backward searching requires a regular expression as the
search pattern. Regular expressions follow the same rules as in the
UNIX editor, ed. These rules can be stated as:
Any displayable character matches itself.
. (period) matches any character except line feed.
^ (circumflex) matches the start of the line.
$ (dollar sign) matches the end of the line.
\c matches the character c (including period, circumflex, etc).
[string] matches any of the characters in the string.
[^string] matches any of the characters except those in the
[x-y] matches any characters between x and y (e.g., [a-z]).
Pattern* matches any number of occurrences of pattern.
Some examples of regular expressions are:
The boy matches the string 'The boy'
^$ matches any empty line.
^.$ matches any line containing exactly 1 character
^A.*\.$ matches any line starting with an A, ending with a
^[A-Z]*$ matches any line containing only capital letters (or
[A-Z0-9] matches any line containing either a capital letter or a
.*X$ matches any line ending in 'X'
A.*B matches any line containing an 'A' and then a 'B'
Control characters cannot be entered into a file simply by typing
them because all of them are editor commands. To enter a control
character, depress the ALT key, and then while holding it down, hit the
ESC key. Release both ALT and ESC and type the control character.
Control characters are displayed in reverse video.
