File uses magic numbers to determine a file type. These magic numbers come with
|
|
File in a plain text file. File internally compiles this database each time it
|
|
is run. This is not the normal type of operation for File since compiling a
|
|
plain text file each time is not the fastest way to do it. File offers an
|
|
option "-C" to compile this magic number file. The reason this isn't done
|
|
automagically is that some people like to work on the magic numbers. On the
|
|
other hand many people didn't get it that they should compile the magic
|
|
numbers, so the author of File added a warning when the plain text magic file
|
|
is used. As we usually won't work on the plain text magic file, we
|
|
compile this file, because it's faster, fixes that annoying warning and is how
|
|
it was meant to be:
