# wrong
while[$count -1e 10]

# right
while [ $count -le 10 ]

I've tried ...

while[$count -le 10]

with same results, but when I included the space before and after ...

while [ $count -le 10 ]

it worked. Why does that space matter?

The same reason you can't put enter keys anywhere you like. That's simply the way the language expects it.

Perhaps an interesting backgrounder is, that [ is one of the names of the 'test' utility (see ls -l /bin/[ ) and in this case it takes 4 parameters : $count , -le , 10 , and ]
