Usage: sed [-inrE] [-f FILE]... [-e CMD]... [FILE]...
or: sed [-inrE] CMD [FILE]...

	-e CMD	Add CMD to sed commands to be executed
	-f FILE	Add FILE contents to sed commands to be executed
	-i[SFX]	Edit files in-place (otherwise sends to stdout)
		Optionally back files up, appending SFX

If no -e or -f, the first non-option argument is the sed command string.
Remaining arguments are input files (stdin if none).
