什么是 5 文件？
A 5 file contains a Unix system-level manual page (man page) that likely documents a file format or convention. It is named for the format or convention it documents. You can access 5 files using the man utility.
更多信息
Unix-like OSes include a system manual that is divided into eight numbered sections. This manual's fifth section usually describes the file formats the system supports. Each supported format is documented in a separate 5 file.
For example, the file deb.5 describes the .DEB file format. It also provides a list of additional related entries.
In some Unix systems, such as System V, 5 files instead contain documentation of miscellaneous system information. These 5 files can still be accessed using the man utility.
注: Other sections' Unix man pages use the .1, .2, .3, .4, .6, .7, and .8 extensions. Man pages are also commonly compressed into .GZ files (which may use the .gz.# extension).
如何打开 5 文件
In Unix-like OSes, you can open a 5 file by calling the man utility using the name of the file. For example, to open deb.5, enter man deb(5).
Since 5 files are plain text files, you can also open them in any text editor, such as Vim (Linux, Mac), Microsoft Notepad (Windows), and Apple TextEdit (Mac).
