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 see one more page of output, q to discard the remaining output, or c to continue without paging for the rest of the current command. 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 height unlimited
set width cpl
set width unlimited
set commands specify a screen height of lpp lines and
a screen width of cpl characters. The associated
commands display the current settings.
If you specify a height of either
unlimited or 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
Likewise, you can specify ‘set width unlimited’ or ‘set width 0’ to prevent GDB from wrapping its output.
set pagination on
set pagination off
Turn the output pagination on or off; the default is on. Turning
pagination off is the alternative to
set height unlimited. Note that
running GDB with the --batch option (see -batch) also automatically disables pagination.
Show the current pagination mode.
