How about 'can put the "then" on a separate line':

if [ "$temp" != "" ]; then

works just fine.  The semicolon terminates the list of statements
forming the condition of the if.

I think there is a problem if you don't double-quote your variable or
leave white space around the "[" and "]" too:

1>@maytag[3]% echo a${temp}a
aa
1>@maytag[4]% if [$temp != '']; then echo blug; else echo bleah; fi
blug

It should echo "bleah"

1>@maytag[12]% if [ "$temp" != "" ]; then echo blug; else echo bleah; fi
bleah
