H A Ddebug-kernel-with-gdb.md179 - **print 和 display**
199   您可以使用`display`命令来持续追踪变量或者表达式,`display`命令用于设置需要持续跟踪并在每次程序停止时显示的表达式。它类似于print命令，但与print不同…
202 display <variable> # 打印对应变量名的值，例如：display my_variable
204 display <expression> # 打印合法表达式的值，例如：display a+b
207 (gdb) display order
208 1: order = core::sync::atomic::Ordering::SeqCst #其中1表示display编号，
209 #您可以通过info display命令来查看所有display编号
213 一旦您设置了display命令，每当程序停止（例如，在断点处停止）时，GDB将自动打印指定表达式的值。
215 display命令非常有用，因为它允许您在调试过程中持续监视表达式的值，而无需每次都手动输入print命令。它特别适用于那些您希望持续跟踪的变量或表达式。
218 &emsp;&emsp;**要取消已设置的display命令并停止自动显示表达式的值，可以使用undisplay命令：**
