12
15 The fnmatch() function matches patterns as described on the fnmatch(5)
16 manual page. It checks the string argument to see if it matches the
17 pattern argument.
18 The flags argument modifies the interpretation of pattern and string.
21 It is the bitwise inclusive OR of zero or more of the following flags
22 defined in the header <fnmatch.h>.
23 FNM_PATHNAME If set, a slash (/) character in string will be
25 explicitly matched by a slash in pattern; it will not
26 be matched by either the asterisk (*) or question-
27 mark (?) special characters, nor by a bracket ([])
28 expression.
29 If not set, the slash character is treated as an
31 ordinary character.
32 FNM_NOESCAPE If not set, a backslash character (\) in pattern fol‐
35 lowed by any other character will match that second
36 character in string. In particular, "\\" will match a
37 backslash in string.
38 If set, a backslash character will be treated as an
40 ordinary character.
41 FNM_PERIOD If set, a leading period in string will match a
44 period in pattern; where the location of "leading" is
45 indicated by the value of FNM_PATHNAME:
46 o If FNM_PATHNAME is set, a period is "lead‐
48 ing" if it is the first character in
49 string or if it immediately follows a
50 slash.
51 o If FNM_PATHNAME is not set, a period is
53 "leading" only if it is the first charac‐
54 ter of string.
55 If not set, no special restrictions are placed on matching a period.
59
61 If string matches the pattern specified by pattern, then fnmatch()
62 returns 0. If there is no match, fnmatch() returns FNM_NOMATCH, which
63 is defined in the header <fnmatch.h>. If an error occurs, fnmatch()
64 returns another non-zero value.
65
67 The fnmatch() function has two major uses. It could be used by an
68 application or utility that needs to read a directory and apply a pat‐
69 tern against each entry. The find(1) utility is an example of this. It
70 can also be used by the pax(1) utility to process its pattern operands,
71 or by applications that need to match strings in a similar manner.
72 The name fnmatch() is intended to imply filename match, rather than
75 pathname match. The default action of this function is to match file‐
76 names, rather than path names, since it gives no special significance
77 to the slash character. With the FNM_PATHNAME flag, fnmatch() does
78 match path names, but without tilde expansion, parameter expansion, or
79 special treatment for period at the beginning of a filename.
80 The fnmatch() function can be used safely in multithreaded applica‐
83 tions, as long as setlocale(3C) is not being called to change the
84 locale.
