perldoc -f glob
glob Returns the value of EXPR with filename expansions such as
standard Unix shell /bin/csh would do. This is the interna
function implementing the "<*.c>" operator, but you can us
directly. If EXPR is omitted, $_ is used. The "<*.c>" oper
is discussed in more detail in "I/O Operators" in perlop.
Beginning with v5.6.0, this operator is implemented using
standard "File::Glob" extension. See File::Glob for detail
Being cautious is good, and i'm sure you knew about glob.
