FNMATCH(3) BSD Programmer's Manual FNMATCH(3)NAMEfnmatch - match filename or pathname using shell globbing rules
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 con-
stants, 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 string must be explicitly matched by
periods in pattern. If this flag is not set, then leading
periods are treated as regular characters. 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 Ignore case distinctions in both the pattern and the
string.
RETURN VALUES
The fnmatch() function returns zero if string matches the pattern speci-
fied by pattern, otherwise, it returns the value FNM_NOMATCH.
SEE ALSOsh(1), glob(3), regex(3)STANDARDS
The fnmatch() function conforms to IEEE Std 1003.2-1992 ("POSIX.2") and
X/Open Portability Guide Issue 4.2 ("XPG4.2").
Note, however, that the flags FNM_LEADING_DIR and FNM_CASEFOLD are exten-
sions and should not be used by applications striving for strict stan-
dards conformance.
HISTORY
The fnmatch() function first appeared in 4.4BSD.
BUGS
The pattern '*' matches the empty string, even if FNM_PATHNAME is speci-
fied.
