too many arguments

Error message

too many arguments

What it means

The 'target follow-exec -off' variant takes no further arguments. The '-off' case turns off exec following via FollowExec(false, ""), and if extra tokens were supplied after '-off' the command rejects them as 'too many arguments'.

Solutions

1. Use 'target follow-exec -off' with no additional arguments.
2. If you meant to set a regex filter, use the enable form: 'target follow-exec -on <regex>' (or without -on) instead.
3. Trim accidental extra tokens from the command.

Example fix

// before
target follow-exec -off myregex
// after
target follow-exec -off

if len(strings.Fields(cmd)) > 3 { return errors.New("target follow-exec -off takes no arguments") }

When it happens

Trigger: Running 'target follow-exec -off <anything>', e.g. 'target follow-exec -off regex' or a stray extra token.

Common situations: Users assuming -off takes the same optional regex that the enable variant accepts (len(argv)==2 there), or leftover text in the command line.
