The trick is to quote both parts of the relation:

while [ "$var" = "somevalue" ] ; do
...

while [ "$var" = "5" ] ; do
...

This way you force the shell to do a string comparison, regardless of what content is stored in "$var".

Hi bakunin,

Ok, but we can't use a string comparison here, we have to use a numerical comparison.
