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 For most purposes, however, it is superseded by full−screen editors such as GNU Emacs or GNU Moe.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

−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

−v, −−verbose

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.
