21.4. 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 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
width commands:
- set height lpp, show height, set width cpl, 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 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.
