The example in this article describes how Java in Android obtains file types based on file headers. Share to everyone for your reference, specific as follows:
We've talked about the MediaFile class inside the Android system to get the file type, which is largely based on the file
/sys/kernel/debug type Debugfs (rw)
None on/sys/kernel/security type SECURITYFS (rw)
Udev On/dev type DEVTMPFS (rw,mode=0755)
Devpts on/dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
Tmpfs on/run type TMPFS (rw,noexec,nosuid,size=10%,mode=0755)
None On/run/lock type TMPFS (rw,noexec,nosuid,nodev,size=5242880)
None On/run/shm type TMPFS (Rw,nosuid,nodev)

First, Linux How are file types differentiated? When it comes to documents, you have to get a quick look at the inode.Inode: An index node that is used to store basic information about a file.The inode is a data structure in the Unix/linux operating system, essentially a struct that defines variables that record information related to the file. A large number of
Hive supports the basic data types supported by many relational databases and supports three collection data types with few relational databases. A related question is how these data types are presented in a text file, or how to describe the storage of text. Compared to most databases, Hive has a feature that provides
