fnmatch
FNMATCH(3) BSD Library Functions Manual FNMATCH(3)NAME
fnmatch -- match filename or pathname using shell glob rules
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 globbing 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 character 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 strings match periods in patterns. 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 immediately follows a slash.
FNM_LEADING_DIR Ignore ``/*'' rest after successful pattern matching.
FNM_CASEFOLD The pattern is matched in a case-insensitive fashion.
RETURN VALUES
The fnmatch() function returns zero if string matches the pattern specified by pattern, otherwise, it returns the value FNM_NOMATCH.
SEE ALSO sh(1), glob(3), regex(3), glob(7)STANDARDS
The fnmatch() function conforms to IEEE Std 1003.2-1992 (``POSIX.2''). The FNM_CASEFOLD flag is a NetBSD extension.
HISTORY
The fnmatch() function first appeared in 4.4BSD.
BUGS
The pattern '*' matches the empty string, even if FNM_PATHNAME is specified.
