uname output: Linux EliteBook 5.16.15-arch1-1 #1 SMP PREEMPT Thu, 17 Mar
2022 00:30:09 +0000 x86_64 GNU/Linux
Machine Type: x86_64-pc-linux-gnu
Bash Version: 5.1
Patch Level: 16
Release Status: release
Description:
PS0:
The value of this parameter is expanded like PS1 and displayed by
interactive shells after reading a command and before the command is
executed.
BASH_COMMAND:
The command currently being executed or about to be executed, unless
the shell is executing a command as the result of a trap, in which
case it is the command executing at the time of the trap. If
BASH_COMMAND is unset, it loses its special properties,
even if it is subsequently reset.
PROBLEM:
By the time PS0 is displayed, BASH_COMMAND is still set to the
previous command, not the command about to be executed.
And that's just about the only problem:
Thank you very much for your good work!!!
Repeat-By:
PS0="$BASH_COMMAND"
Fix:
Assign BASH_COMMAND before expanding PS0
