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 For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.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

-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

-r, --restricted run in restricted mode

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

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

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

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 (e.g., bug) which caused ed to panic.
