22.4 Screen Size
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 width commands:
set height lpp
set height unlimited
show height
set width cpl
set width unlimited
show width
These set commands specify a screen height of lpp lines and
a screen width of cpl characters. The associated show
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
buffer.
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 pagination
Show the current pagination mode.
