====== Solution: More ======

**Start with the [[Brainteaser More|Brainteaser: More]] page.**

Did you solve the problem?

If the stdout of the ''more'' (or ''less'') program is tied up with input from another process, the two remaining standard file descriptors (stdout and stderr) are still connected to the terminal.

The ''more'' command reads the keyboard input from stdout. Although we think of stdout and stderr as being used for output only, they are two-way connections, and therefore can be used to read from the terminal!
