The call stack is displayed when an exception is returned when an invalid parameter is displayed during command line association.

def resolve_command(
self, ctx: Context, args: list[str]
) -> tuple[str | None, Command | None, list[str]]:
cmd_name = make_str(args[0])
original_cmd_name = cmd_name

    # Get the command
    cmd = self.get_command(ctx, cmd_name)

when get_command return ctx.fail，he call stack is displayed

Can only the error message be retained and the call stack is not printed?

Environment:

• Python version: 3.9
• Click version: 7.1.2

Seems like spam since your github is only 2 days old. Can you reply with some more details so I know its legit.

We use the click component. If the previous parameter of the command line is not completely written and multiple parameters can be matched, for example, the command line "show i ", i can match parameters such as ip and interface, and then press Tab to associate the next parameter, the command line will display the call stack.

example：
adminadmin@sonic:~# show i Traceback (most recent call last):
File "/usr/local/bin/show", line 8, in
sys.exit(cli())
