The file(1) command uses a file of "magic numbers" stored in /etc/magic to recognize file formats. Additional formats can be recognized by adding appropriate entries there, or in an alternate "magic numbers" file specified by the -m option.

This brings up something i have been wondering about for some time. SCO's Xenix has a "file" program, but it only knows so many types. I sometimes FTP files from BSD systems and loose part of the filename because of the Xenix filename length limit. SCO does not recognize compressed files at, it just says data. Is the source for a file like program available on the net? Is there a BSD file program that is free of AT&T code? > >The file(1) command uses a file of "magic numbers" stored in /etc/magic >to recognize file formats.

If the -f option is given, file takes the list of filenames from namesfile. If the -m option is given, file sets the access time for the examined file to the current time. Otherwise, the access time remains unchanged. . . .
