Description
The pg command reads a file name from the File parameter and
writes the file to standard output one screen at a time. If you
specify a - (dash) as the File parameter, or run the pg command
without options, the pg command reads standard input. Each
screen is followed by a prompt. If you press the Enter key,
another page is displayed. Subcommands used with the pg command
let you review or search in the file.
