-bash: PROMPT_COMMAND: readonly variable

[ifdongs]

The root administrator sets the variables to read only. Is there any other way to use z.lua?

Best Regards.

sure，change to zsh

yes, I found that the most commonly used cmds are cd and ls, so I created a new temp variable and combined it with cd and ls.

可以以这种方式取消 gdb -ex 'call (int)unbind_variable("PROMPT_COMMAND")' --pid=$$ --batch
