- NAME
- e - screen editor
-
- SYNOPSIS
- e [ -bullets ] [ -inplace ] [ -replay=repfile ] [
- -term=terminal ] [ file ]
-
- DESCRIPTION
- E is a more recent version of ned(C). Apart from having
- many more commands and being slightly faster, the version of
- e as installed avoids use of control-P, control-Q and
- control-S. This means that it is likely to work over non-
- transparent networks such as the Cambridge ring.
-
- Some of the options are:
-
- -bullets
- Display marks on the window edge to show the current
- cursor position.
-
- -inplace
- If the file being edited is a link, don't break this
- on exit.
-
- -replay=repfile
- Commands are taken from the saved keystroke file,
- repfile. The keystrokes will be left in .ek1 in the
- event of a crash or abort; this file must be renamed
- to use this option. If the file is present, but the
- option is not given, e will ask whether a replay is
- required.
-
- -term=terminal
- this overrides the terminal type. By default e looks
- for the TERM environment variable; if even this is
- missing, e assumes an adm5.
-
- If e is invoked with no file argument, it uses the saved
- state file, .es1, and rebuilds the screen exactly as it was
- on exit the last time.
-
- If file is given, and it does not exist, you will be asked
- to confirm the creation by typing y.
-
- The secret of successful editing is never to do too much at
- once. If you crash after 2 hours solid typing and lose
- everything, please don't come crying to the system
- administrator! Exit from e (or any editor for that matter)
- at regular intervals so that your data is saved to disk.
-
- Certain terminals, notably the ibmpc, require keyboard
- initialisation. On entry and exit, e looks in directories

-
- $HOME/e, $HOME and /usr/lib/e for the appropriate files. The
- filename is .e<terminal>.<x> where <terminal> is the
- specified terminal type and <x> is i for entry (initialise)
- and r for exit (reset).
-
- The order of directory searching means that the user can set
- up his/her own initialisation to override the system
- defaults if required. The files are simply transmitted raw
- to the terminal.
-
- TERMINALS
- Recognised terminal types are currently: adm5, ibmpc and
- vt100. The adm5 driver should handle look-alikes such as
- the dt22, ibmpc assumes the use of the uc terminal emulator,
- and vt100 should handle standard ANSI terminals.
-
- BUGS
- Replays are dangerous - make sure you have a copy of the
- relevant file(s) before attempting one.
-
- FILES
- /usr/lib/e library files directory
- /tmp/etmp emergency temporary directory
- .ec1 changes file
- .ek1 keystroke file
- .ek1b backup keystroke file
- .es1 saved state file
-
- LOCAL
- A local version is available for the PC. To date, all
- functions are implemented except those requiring to fork()
- and exec() other programs. Backups are prepended with "%",
- while temporary files start with "&", since DOS rejects the
- respective "," and "." used on this system.
-
- The ELIB environment variable must be set to the location of
- the library files, though the default above will work if it
- is on the current drive. To enable editing while in the
- root of any DOS drive, the variable TMP must define a
- suitable temporary directory; otherwise the default
- directory \tmp\etmp must exist on that drive (DOS roots have
- no '.' or '..' entries).
