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.
- FNM_EXTMATCH
-
If this flag (a GNU extension) is set, extended patterns are
supported, as introduced by 'ksh' and now supported by other shells.
The extended format is as follows, with pattern-list
being a '|' separated list of patterns.
- '?(pattern-list)'
-
The pattern matches if zero or one occurrences of any of the
patterns in the pattern-list match the input string.
- '*(pattern-list)'
-
The pattern matches if zero or more occurrences of any of the
patterns in the pattern-list match the input string.
- '+(pattern-list)'
-
The pattern matches if one or more occurrences of any of the
patterns in the pattern-list match the input string.
- '@(pattern-list)'
-
The pattern matches if exactly one occurrence of any of the
patterns in the pattern-list match the input string.
- '!(pattern-list)'
-
The pattern matches if the input string cannot be matched with
any of the patterns in the pattern-list.
RETURN VALUE
Zero if
string
matches
pattern,
FNM_NOMATCH
if there is no match or another nonzero value if there is an error.
