[Linux-aus] enum in /etc/magic

[Chris Martin]

Russell

There is no way to shorten the test that I am aware of.
The ">" indicates the level of the test,  so I ma thinking that you should
be use an extra ">" when you get to the 3rd test

ie:

0       beshort                 0xfe01          MySQL table definition file
>2      byte                    x               Version %d,
>>3      byte                    9               Type MYISAM
>>3      byte                    12              Type INNODB

The first test identifies it as a SQL table file
The second test displays the version
The 3rd test displays the Type

You will need one line for each type





Cheers
