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 For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.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’.

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.
