If you want to do the right thing, independent of the characters in the filenames and the value of the IFS environment variable, use the later. TL;DR: *.ext work when filenames contain spaces; $(ls *.ext) doesn't. -- Boyd Stephen Smith Jr. ,= ,-_-. =. bss@iguanasuicide.net ((_/)o o(\_)) ICQ: 514984 YM/AIM: DaTwinkDaddy `-'(. .)`-' http://iguanasuicide.net/ \_/
