@(#)fnmatch.3 8.3 (Berkeley) 4/28/95
.Dd November 30, 2010 .Dt FNMATCH 3 .Os .Sh NAME .Nm fnmatch .Nd match filename or pathname using shell glob rules .Sh LIBRARY .Lb libc .Sh SYNOPSIS n fnmatch.h .Ft int .Fn fnmatch "const char *pattern" "const char *string" "int flags" .Sh DESCRIPTION The .Fn fnmatch function matches patterns according to the globbing rules used by the shell. It checks the string specified by the .Fa string argument to see if it matches the pattern specified by the .Fa pattern argument.
p The .Fa flags argument modifies the interpretation of .Fa pattern and .Fa string . The value of .Fa flags is the bitwise inclusive .Tn OR of any of the following constants, which are defined in the include file
a fnmatch.h . l -tag -width FNM_LEADING_DIRXX t Dv FNM_NOESCAPE Normally, every occurrence of a backslash
q Ql \e followed by a character in .Fa pattern is replaced by that character. This is done to negate any special meaning for the character. If the .Dv FNM_NOESCAPE flag is set, a backslash character is treated as an ordinary character. t Dv FNM_PATHNAME Slash characters in .Fa string must be explicitly matched by slashes in .Fa pattern . If this flag is not set, then slashes are treated as regular characters. t Dv FNM_PERIOD Leading periods in strings match periods in patterns. The definition of ``leading'' is related to the specification of .Dv FNM_PATHNAME . A period is always ``leading'' if it is the first character in .Ar string . Additionally, if .Dv FNM_PATHNAME is set, a period is ``leading'' if it immediately follows a slash. t Dv FNM_LEADING_DIR Ignore .Dq /* rest after successful .Fa pattern matching. t Dv FNM_CASEFOLD The pattern is matched in a case-insensitive fashion. .El .Sh RETURN VALUES The .Fn fnmatch function returns zero if .Fa string matches the pattern specified by .Fa pattern , otherwise, it returns the value .Dv FNM_NOMATCH . .Sh SEE ALSO .Xr sh 1 , .Xr glob 3 , .Xr regex 3 , .Xr glob 7 .Sh STANDARDS The .Fn fnmatch function conforms to .St -p1003.2-92 . The .Dv FNM_CASEFOLD flag is a .Nx extension. .Sh HISTORY The .Fn fnmatch function first appeared in x 4.4 . .Sh BUGS The pattern .Ql * matches the empty string, even if .Dv FNM_PATHNAME is specified.
