# suffixes - list of file suffixes - man(7) - [phpMan] [_SUFFIXES_(7)](https://www.chedong.com/phpMan.php/man/SUFFIXES/7/markdown) Miscellaneous Information Manual [_SUFFIXES_(7)](https://www.chedong.com/phpMan.php/man/SUFFIXES/7/markdown) ## NAME suffixes - list of file suffixes ## DESCRIPTION It is customary to indicate the contents of a file with the file suffix, which (typically) consists of a period, followed by one or more letters. Many standard utilities, such as com‐ pilers, use this to recognize the type of file they are dealing with. The [**make**(1)](https://www.chedong.com/phpMan.php/man/make/1/markdown) utility is driven by rules based on file suffix. Following is a list of suffixes which are likely to be found on a Linux system.
