Notes

In addition to the file command, this package also provides the magic.mgc data file that is typically available at /usr/share/misc/magic.mgc

The MAGIC environment variable is commonly used for instructing applications to look for this file in a nonstandard location. A PHP application, for example, could be configured to make use of this magic.mgc file by adding a custom runtime environment variable to the application's plan.sh:

do_setup_environment() {
  set_runtime_env MAGIC "$(pkg_path_for file)/share/misc/magic.mgc"
}
