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 For most purposes, however, it is superseded by full-screen editors such as GNU Emacs or GNU Moe.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