Read one character of input?

[Leif K-Brooks]

I'm trying to write a Brainfuck interpreter in Perl out of boredom and
desire to improve my skills. I'm running into one prroblem, though:
Brainfuck needs to read one character of input at a time, and I'm not
sure how to it. I've considered reading a line of input at a time and
giving it to the Brainfuck program one character at a time, but is there
a better/easier way?

RTFM: 'perldoc -q single':
How can I read a single character from a file? From the keyboard?
