設置命令提示符

例子

$ gdb -q `which gdb`
Reading symbols from /home/xmj/install/binutils-gdb-git/bin/gdb...done.
(gdb) r -q
Starting program: /home/xmj/install/binutils-gdb-git/bin/gdb -q
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
(gdb)

技巧

當你用gdb來調試gdb的時候，通過設置命令提示符，可以幫助你區分這兩個gdb：

$ gdb -q `which gdb`
Reading symbols from /home/xmj/install/binutils-gdb-git/bin/gdb...done.
(gdb) set prompt (main gdb) 
(main gdb) r -q
Starting program: /home/xmj/install/binutils-gdb-git/bin/gdb -q
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
(gdb) 

注意，這裡set prompt (main gdb)結尾處是有一個空格的。
