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