Re^3: Progress Bar in Perl script

[kcott]

Each of the sails is created by prepending a "\b" to the spinner character:

my @sails = map { "\b$_" } qw{- \ | /};

"\b" is a backspace character; so, when each sail is printed, it deletes the previous one. In the initial state, "Running:" is followed by two spaces (print q{Running:  };); the second space is overwritten by the first sail.

"\b", and other special characters, are listed in perlop: Quote and Quote-like Operators.

D'oh! Thanks! I knew I was overlooking something...
