You didn't tell sed to do that. You also didn't tell *us* you wanted that. The key part is "etc." (i.e. "and others"), you never indicated you wanted anything other than the 1st, 2nd, and 4th lines.

I already did my homework and have my degree; I don't intend to do yours. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
