fnmatch

FNMATCH(3)						   BSD Library Functions Manual 						FNMATCH(3)

NAME

     fnmatch -- test whether a filename or pathname matches a shell-style pattern

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 character is treated as an ordi-
		   nary 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 specified by pattern.  It returns the value FNM_NOMATCH if no match is
     found.  Otherwise, another non-zero value is returned on error.

LEGACY 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)

STANDARDS

     The current implementation of the fnmatch() function does not conform to IEEE Std 1003.2 (``POSIX.2'').  Collating symbol expressions, equiv-
     alence class expressions and character class expressions are not supported.

HISTORY

     The fnmatch() function first appeared in 4.4BSD.

BUGS

     The pattern '*' matches the empty string, even if FNM_PATHNAME is specified.
