[6] The –pager option is not available under Windows. % mysql –pager=/usr/bin/less –pager by itself tells mysql to use your default pager, as specified in your PAGER environment variable: % mysql –pager If your PAGER variable isn’t set, you must either define it or use the first form of the command to specify a pager program explicitly. To define PAGER, use the instructions in Recipe 1.9 for setting environment variables. Within a mysql session, you can turn paging on and off using P and n. P without an argument enables paging using the program specified in your PAGER variable. P with an argument enables paging using the argument as the name of the paging program: mysql> P PAGER set to /bin/more mysql> P /usr/bin/less PAGER set to /usr/bin/less mysql> n PAGER set to stdout Output paging was introduced in MySQL 3.23.28. Another way to deal with long result sets is to use a terminal program that allows you to scroll back through previous output. Programs such as xterm for the X Window System, Terminal for Mac OS X, MacSSH or BetterTelnet for Mac OS, or Telnet for Windows allow you to set the number of output lines saved in the scrollback buffer. Under Windows NT, 2000, or XP, you can set up a DOS window that allows scrollback using the following procedure: 1. Open the Control Panel. 2. Create a shortcut to the MS-DOS prompt by right clicking on the Console item and dragging the mouse to where you want to place the shortcut (on the desktop, for example). 3. Right click on the shortcut and select the Properties item from the menu that appears. 4. Select the Layout tab in the resulting Properties window. 5. Set the screen buffer height to the number of lines you want to save and click the OK button. Now you should be able to launch the shortcut to get a scrollable DOS window that allows output produced by commands in that window to be retrieved by using the scrollbar. 1.21 Sending Query Output to a File or to a Program 1.21.1 Problem You want to send mysql output somewhere other than to your screen. 1.21.2 Solution
