ex, edit - text editor SYNOPSIS
ex [ - ] [ -v ] [ -t tag ] [ -r ] [ +command ] [ -l ] name ... edit [ ex options ] DESCRIPTION
Ex is the root of a family of editors: edit, ex and vi. Ex is a superset of ed, with the most notable extension being a display editing facility. Display based editing is the focus of vi. If you have not used ed, or are a casual user, you will find that the editor edit is convenient for you. It avoids some of the complexi- ties of ex used mostly by systems programmers and persons very familiar with ed. If you have a CRT terminal, you may wish to use a display based editor; in this case see vi(1), which is a command which focuses on the display editing portion of ex. DOCUMENTATION
The document Edit: A tutorial (USD:14) provides a comprehensive introduction to edit assuming no previous knowledge of computers or the UNIX system. The Ex Reference Manual - Version 3.7 (USD:16) is a comprehensive and complete manual for the command mode features of ex, but you cannot learn to use the editor by reading it. For an introduction to more advanced forms of editing using the command mode of ex see the editing documents written by Brian Kernighan for the editor ed; the material in the introductory and advanced documents works also with ex. An Introduction to Display Editing with Vi (USD:15) introduces the display editor vi and provides reference material on vi. In addition, the Vi Quick Reference card summarizes the commands of vi in a useful, functional way, and is useful with the Introduction. FILES

Originally written by William Joy Mark Horton has maintained the editor since version 2.7, adding macros, support for many unusual terminals, and other features such as word abbreviation mode. BUGS
The undo command causes all marks to be lost on lines changed and then restored if the marked lines were changed. Undo never clears the buffer modified condition. The z command prints a number of logical rather than physical lines. More than a screen full of output may result if long lines are present. File input/output errors don't print a name if the command line `-' option is used. There is no easy way to do a single scan ignoring case. The editor does not warn if text is placed in named buffers and not used before exiting the editor. Null characters are discarded in input files, and cannot appear in resultant files. 4th Berkeley Distribution October 21, 1996 EX(1)

ELVIS(1)						      General Commands Manual							  ELVIS(1)

elvis, ex, vi - The editor SYNOPSIS
elvis [flags] [+cmd] [files...] DESCRIPTION
Elvis is a text editor which emulates vi/ex. On systems which pass the program name as an argument, such as Unix and Minix, you may also install elvis under the names "ex", "vi", "view", and "input". These extra names would normally be links to elvis; see the "ln" shell command. When elvis is invoked as "vi", it behaves exactly as though it was invoked as "elvis". However, if you invoke elvis as "view", then the readonly option is set as though you had given it the "-R" flag. If you invoke elvis as "ex", then elvis will start up in the colon com- mand mode instead of the visual command mode, as though you had given it the "-e" flag. If you invoke elvis as "input" or "edit", then elvis will start up in input mode, as though the "-i" flag was given. OPTIONS
-r To the real vi, this flag means that a previous edit should be recovered. Elvis, though, has a separate program, called elvrec(1), for recovering files. When you invoke elvis with -r, elvis will tell you to run elvrec. -R This sets the "readonly" option, so you won't accidentally overwrite a file. -t tag This causes elvis to start editing at the given tag. -m [file] Elvis will search through file for something that looks like an error message from a compiler. It will then begin editing the source file that caused the error, with the cursor sitting on the line where the error was detected. If you don't explicitly name a file, then "errlist" is assumed. -e Elvis will start up in colon command mode. -v Elvis will start up in visual command mode. -i Elvis will start up in input mode. -w winsize Sets the "window" option's value to winsize. +command or -c command If you use the +command parameter, then after the first file is loaded command is executed as an EX command. A typical example would be "elvis +237 foo", which would cause elvis to start editing foo and then move directly to line 237. The "-c command" vari- ant was added for UNIX SysV compatibility. FILES
/tmp/elv* During editing, elvis stores text in a temporary file. For UNIX, this file will usually be stored in the /tmp directory, and the first three characters will be "elv". For other systems, the temporary files may be stored someplace else; see the version-specific section of the documentation. tags This is the database used by the :tags command and the -t option. It is usually created by the ctags(1) program. .exrc or elvis.rc On UNIX-like systems, a file called ".exrc" in your home directory is executed as a series of ex commands. A file by the same name may be executed in the current directory, too. On non-UNIX systems, ".exrc" is usually an invalid file name; there, the initializa- tion file is called "elvis.rc" instead.

There is no LISP support. Certain other features are missing, too. Auto-indent mode is not quite compatible with the real vi. Among other things, 0^D and ^^D don't do what you might expect. Long lines are displayed differently. The real vi wraps long lines onto multiple rows of the screen, but elvis scrolls sideways. AUTHOR
Steve Kirkendall Many other people have worked to port elvis to various operating systems. To see who deserves credit, run the :version command from within elvis, or look in the system-specific section of the complete documentation. ELVIS(1)
