Trying to understand how to add custom files to photorec.  All the examples are specific to being line "0" of the offset signature.  
I will use this as an example.
[root@sysadminnas ~]# hexdump -C pre.dat | head
00000000  34 20 20 20 20 20 20 20  00 00 00 07 00 00 00 00  |4       ........|
00000010  00 00 00 02 00 00 00 00  00 00 00 00 00 00 00 00  |................|
00000020  00 00 00 00 20 20 00 00  00 00 20 20 20 20 00 00  |....  ....    ..|
00000030  00 00 00 00 00 00 53 4f  4c 55 54 49 4f 4e 20 20  |......SOLUTION  |
00000040  20 20 20 20 20 20 20 20  20 20 20 20 20 20 20 20  |                |
Trying to key off of SOLUTION.  Not sure what I am missing.
dat 3 "SOLUTION"
The only ones that seem to work are on the first line.  Like so.
dat 0 "4"
I appreciate any and all assistance.

Re: Custom Files
Seems like this should be an easy one.  I don't see why I can't key off of anything other than the first line.
