Do you know where that leading ':' is coming from? It's sometimes used as shorthand for 'true' in shell scripts, and 'true' is sometimes used as a low-effort 'no-op', but the 'exec' builtin (rightfully) doesn't care about any of that:
moloch:~λ exec : -bash: exec: :: not found Kind regards, T G-R Sent on the go. Excuse or enjoy my brevity.
