1. Using "ls" is unnecessary; "echo" would suffice.

2. If you have bash, you can also eliminate the use of "sed", e.g.

	for i in 0*.asd ; do
	    /bin/mv -- "$i" "a${i#0}"
	done

Also, a couple of general scripting tips:

1. Shell variables should usually be enclosed in double quotes,
otherwise you will get undesired behaviour if the value contains
whitespace.

2. If the first argument to a command is a variable, you should allow
for the case where it begins with a dash, e.g. by using "--" (this
isn't any issue in this specific case, as the filename is guaranteed
to begin with a "0").
