FNMATCH(3) BSD Library Functions Manual FNMATCH(3)
NAME
fnmatch -- match filename or pathname
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <fnmatch.h>
int
fnmatch(const char *pattern, const char *string, int flags);
DESCRIPTION
The fnmatch() function matches patterns according to the rules used by the shell. It checks
the string specified by the string argument to see if it matches the pattern specified by
the pattern argument.
The flags argument modifies the interpretation of pattern and string. The value of flags is
the bitwise inclusive OR of any of the following constants, which are defined in the include
file fnmatch.h.
FNM_NOESCAPE Normally, every occurrence of a backslash ('\') followed by a character in
pattern is replaced by that character. This is done to negate any special
meaning for the character. If the FNM_NOESCAPE flag is set, a backslash char-
acter is treated as an ordinary character.
FNM_PATHNAME Slash characters in string must be explicitly matched by slashes in pattern.
If this flag is not set, then slashes are treated as regular characters.
FNM_PERIOD Leading periods in string must be explicitly matched by periods in pattern.
If this flag is not set, then leading periods are treated as regular charac-
ters. The definition of "leading" is related to the specification of
FNM_PATHNAME. A period is always "leading" if it is the first character in
string. Additionally, if FNM_PATHNAME is set, a period is leading if it imme-
diately follows a slash.
FNM_LEADING_DIR
Ignore /* rest after successful pattern matching.
FNM_CASEFOLD Ignore case distinctions in both the pattern and the string.
RETURN VALUES
The fnmatch() function returns zero if string matches the pattern specified by pattern, oth-
erwise, it returns the value FNM_NOMATCH.
SEE ALSO
sh(1), glob(3), regex(3)
STANDARDS
The fnmatch() function conforms to IEEE Std 1003.2 ("POSIX.2").
HISTORY
The fnmatch() function first appeared in 4.4BSD.
BUGS
The pattern '*' matches the empty string, even if FNM_PATHNAME is specified.
