Square brackets wouldn't do the trick. The shell construction
if ! foo; then
is supposed to negate the sense of the exit status of foo (which is a
program, not a test expression). Unfortunately, the Solaris /bin/sh
doesn't appear to support that syntax. So the uglier but more portable
if foo; then :; else
needs to be used. (You can't even omit the command in the body of the
statement. Annoying.)
This problem affects all show-* scripts, and was introduced on July
10.
