Your program's input and output
By default, the program you run under GDB does input and output to the
same terminal that GDB uses. GDB switches the terminal to its own
terminal modes to interact with you, but it records the terminal modes
your program was using and switches back to them when you continue
running your program.
Displays information recorded by GDB about the terminal modes your
program is using.
You can redirect your program's input and/or output using shell
redirection with the `run' command. For example,
run > outfile
starts your program, diverting its output to the file `outfile'.
Another way to specify where your program should do input and output
is with the `tty' command. This command accepts a file name as
argument, and causes this file to be the default for future `run'
commands. It also resets the controlling terminal for the child
process, for future `run' commands. For example,
directs that processes started with subsequent `run' commands default
to do input and output on the terminal `/dev/ttyb' and have that as
their controlling terminal.
An explicit redirection in `run' overrides the `tty' command's
effect on the input/output device, but not its effect on the controlling
When you use the `tty' command or redirect input in the `run'
command, only the input _for your program_ is affected. The input for
GDB still comes from your terminal.
