OK, second try at the question:
I'm using sh to impliment an IF statement. Can't get it to work.
Here's the code:
#!/bin/sh
if [$temp != ''] then
echo 'remote-caller' >> .people;
else
echo 'inside-caller' >> .people;
fi
I keep getting an ELSE UNEXPECTED.
So, I tried an ELIF, but no go.
Any answers?
(as you can see, I'm new to sh!)
thanx

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

Also, for [ ... ] to check for an empty string, it isn't necessary to compare with "" (or ''). The following should work. # #!/bin/sh if [ "$temp" ] # Note the quotes then echo 'remote-caller' >> .people else echo 'inside-caller' >> .people fi # Chee Wai
