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 consists of a period, followed by one or more letters. Many
11 standard utilities, such as compilers, use this to recognize the type
12 of file they are dealing with. The make(1) utility is driven by rules
13 based on file suffix.
14 Following is a list of suffixes which are likely to be found on a Linux
16 system.
