How to capture a copy of the output (for PRINTING)
There are two ways to capture your program's output in a file.
The first way is to use "output redirection". If your program does not
require you to type in data at the keyboard, you can redirect the output from
the program into a file by typing this command:
a.out > foo
This method puts output into a file named 'foo'; it does not display anything
on your screen.
If you need to enter data from the keyboard, you probably want to use the
'script' command. Script makes a copy of everything that is printed on your
terminal. To use 'script', first type this command:
script foo
The machine will respond:
Script started, file is foo
Then run your program normally. When the program is done, type:
exit
The machine will respond:
Script done, file is foo
You can use the 'more' command to view the file on your terminal screen, or
you can print the output file on a printer as you would any other file.
