Just an exerpt from of $! perldoc perlvar.
In the above *meaningless* stands for anything: zero, non-zero,
"undef". A successful system or library call does not set the
variable to zero.
If used an a string, yields the corresponding system error
string. You can assign a number to $! to set *errno* if, for
instance, you want "$!" to return the string for error *n*, or
you want to set the exit value for the die() operator.
