NAME

       ed - line-oriented text editor

SYNOPSIS

       ed [options] [[+line] 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 For most purposes, however, it is superseded by full-screen editors
       such as GNU Emacs or GNU Moe.

       The file name may be preceded by '+line', '+/RE', or '+?RE' to set the current line to the
       line number specified or to the first or last line matching the regular expression 'RE'.

OPTIONS

       -h, --help
              display this help and exit

       -V, --version
              output version information and exit

       -E, --extended-regexp
              use extended regular expressions

       -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

       -q, --quiet, --silent
              suppress diagnostics written to stderr

       -r, --restricted
              run in restricted mode

       -s, --script
              suppress byte counts and '!' prompt

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

       --strip-trailing-cr
              strip carriage returns at end of text lines

       --unsafe-names
              allow control characters 1-31 in file names

       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  (invalid  command-line
       options,  memory exhausted, command failed, etc), 2 for problems with the input file (file
       not found, buffer modified, I/O errors), 3 for an internal consistency error  (e.g.,  bug)
       which caused ed to panic.
