You are doing string comparison with this syntax in either bash or Korn shells (and I believe that you need [[ and ]] to use ==). With string comparison you have to be careful as you might not get what you expect. Consider the statement where the variables evaluate to something like this:

Code:
if [[ 0040% > 30% ]]

Written this way, the expression will evaluate to false, not true as you might expect.

If you use the (deprecated) form with 'gt' instead of '>' to force a numeric comparison
Code:
if [[ 0040% -gt 30% ]]

you will get an error: 40%: more tokens expected

If you wrote the if statement in ksh/bash using the current standard it would also fail if the variables evaluate to a string with a trailing %:

Code:
x=60%
y=50%
if (( $x > $y ))
then
    echo "true"
else
    echo "false"
fi

running this in ksh yields: line 6: 60% > 50% : arithmetic syntax error.

       required to run ldap2dns under daemontools.

       Run this script within your tinydns directory.
       For example: root@host[/var/tinydns]# ldap2tinydns-conf

       This creates the ldap2tinydns directory under your tinydns directory and adds the default configuration under ldap2tinydns/env.
