#glob EXPR

#glob

In list context, returns a (possibly empty) list of filename expansions on the value of EXPR such as the standard Unix shell /bin/csh would do. In scalar context, glob iterates through such filename expansions, returning undef when the list is exhausted. This is the internal function implementing the <*.c> operator, but you can use it directly. If EXPR is omitted, $_ is used. The <*.c> operator is discussed in more detail in "I/O Operators" in perlop.

Note that glob will split its arguments on whitespace, treating each segment as separate pattern. As such, glob('*.c *.h') would match all files with a .c or .h extension. The expression glob('.* *') would match all files in the current working directory.

Beginning with v5.6.0, this operator is implemented using the standard File::Glob extension. See File::Glob for details, including bsd_glob which does not treat whitespace as a pattern separator.
