Re: [gentoo-user] [OT] One line script for md5sum

[smallnow]

token* is the best. I also have this useful script in my bashrc.

its just an extended version of this.
[[ $(md5sum < file1) == $(md5sum < file2) ]]

so you can just give it two files as its argument and it returns 0 if they are
the same. -v for verbose

md5() {
	local v x y;
	[[ $1 == -v ]] && [[ $# == 3 ]] && { v=true; shift; }
	if [[ $# != 2 ]]; then
		[[ $v ]] && echo Error: need 2 arguments.
		return 2
	fi
	if [[ $v ]]; then
		x=$(md5sum < "$1" ) || return 2
		y=$(md5sum < "$2" ) || return 2
	else
		{ x=$(md5sum < "$1" ) ;} &> /dev/null || return 2
		{ y=$(md5sum < "$2" ) ;} &> /dev/null || return 2
	fi
	if [[  $x == $y ]]; then
		[[ $v ]] && echo Same.
		return 0
	else
		[[ $v ]] && echo Different.
		return 1
	fi
}
