6 suffixes - list of file suffixes
7
9 It is customary to indicate the contents of a file with the file suf‐
10 fix, which (typically) consists of a period, followed by one or more
11 letters. Many standard utilities, such as compilers, use this to rec‐
12 ognize the type of file they are dealing with. The make(1) utility is
13 driven by rules based on file suffix.
14 Following is a list of suffixes which are likely to be found on a Linux
16 system.
