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, 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. BSD

NAME
fnmatch - match filename or pathname SYNOPSIS
#include <fnmatch.h> int fnmatch(const char *pattern, const char *string, int flags); DESCRIPTION
The fnmatch() function checks whether the string argument matches the pattern argument, which is a shell wildcard pattern. The flags argument modifies the behavior; it is the bitwise OR of zero or more of the following flags: FNM_NOESCAPE If this flag is set, treat backslash as an ordinary character, instead of an escape character. FNM_PATHNAME If this flag is set, match a slash in string only with a slash in pattern and not by an asterisk (*) or a question mark (?) metacharacter, nor by a bracket expression ([]) containing a slash. FNM_PERIOD If this flag is set, a leading period in string has to be matched exactly by a period in pattern. A period is considered to be leading if it is the first character in string, or if both FNM_PATHNAME is set and the period immediately follows a slash. FNM_FILE_NAME This is a GNU synonym for FNM_PATHNAME. FNM_LEADING_DIR If this flag (a GNU extension) is set, the pattern is considered to be matched if it matches an initial segment of string which is followed by a slash. This flag is mainly for the internal use of glibc and is implemented only in certain cases. FNM_CASEFOLD If this flag (a GNU extension) is set, the pattern is matched case-insensitively. RETURN VALUE
Zero if string matches pattern, FNM_NOMATCH if there is no match or another nonzero value if there is an error. CONFORMING TO
POSIX.2. The FNM_FILE_NAME, FNM_LEADING_DIR, and FNM_CASEFOLD flags are GNU extensions. SEE ALSO
