NAME
       ed - line-oriented text editor

SYNOPSIS
       ed [options] [file]

DESCRIPTION
       GNU  ed  is a line-oriented text editor. It is used to create, display,
       modify and otherwise manipulate text files, both interactively and  via
       shell  scripts. A restricted version of ed, red, can only edit files in
       the current directory and cannot execute  shell  commands.  Ed  is  the
       'standard'  text editor in the sense that it is the original editor for
       Unix, and thus widely available. For most purposes, however, it is  su-
       perseded by full-screen editors such as GNU Emacs or GNU Moe.

OPTIONS
       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -G, --traditional
              run in compatibility mode

       -l, --loose-exit-status
              exit with 0 status even if a command fails

       -p, --prompt=STRING
              use STRING as an interactive prompt

       -r, --restricted
              run in restricted mode

       -s, --quiet, --silent
              suppress diagnostics, byte counts and '!' prompt

       -v, --verbose
              be verbose; equivalent to the 'H' command

       Start edit by reading in 'file' if given.  If 'file' begins with a '!',
       read output of shell command.

       Exit status: 0 for a normal exit, 1 for  environmental  problems  (file
       not  found, invalid flags, I/O errors, etc), 2 to indicate a corrupt or
       invalid input file, 3 for an internal consistency error (eg, bug) which
       caused ed to panic.
