Further guess (but informed by a brief read-up in UNIX in a Nutshell):
The conditions for an 'if' statement should be enclosed in parentheses,
rather than using the [ or test. However, it may still do funky stuff
with the command substitution...
The block syntax for "if" statements is:
if (expr) then
cmds
endif
===========
if (expr) then
cmds
else
cmds
endif
==========
if (expr) then
cmds
else if (expr) then
cmds2
else
cmds3
endif
HTH,
Dan
