You don't need the braces then; they were necessary when there were multiple commands after the "||" (that's "or" to you).

Nope, you'll need to put the braces back in, sorry! (-:

rm file* rm tes* exit99 is a single command, it would try to remove file*, rm, tes*, and exit99. To put multiple commands on the same line, separate them with semicolons.

Code:
test -s file || { rm file* tes*; exit 99; }
