Certain commands to GDB may produce large amounts of information output to the screen. To help you read all of it, GDB pauses and asks you for input at the end of each page of output. Type RET when you want to continue the output, or q to discard the remaining output. Also, the screen width setting determines when to wrap lines of output. Depending on what is being printed, GDB tries to break the line at a readable place, rather than simply letting it overflow onto the following line.
Normally GDB knows the size of the screen from the terminal
driver software. For example, on Unix GDB uses the termcap data base
together with the value of the
TERM environment variable and the
stty rows and
stty cols settings. If this is not correct,
you can override it with the
set height and
set height lpp
set width cpl
setcommands specify a screen height of lpp lines and a screen width of cpl characters. The associated
showcommands display the current settings.
If you specify a height of zero lines, GDB does not pause during output no matter how long the output is. This is useful if output is to a file or to an editor buffer.
Likewise, you can specify `set width 0' to prevent GDB from wrapping its output.
