### 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 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.

`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 0`. Note that running gdb with the `--batch` option (see -batch) also automatically disables pagination.
`show pagination`
  Show the current pagination mode.
