Well, you can get a similar effect tersely via
test -f file || { echo "file not found"; exit 2; }
but you may want to say
test -f file || { echo >&2 "file not found"; exit 2; }
And I think that may be the difficulty with making this an additional
function of "exit", there may well be too many variants in common use to
allow a simple extension to "exit" to cover the bulk of all uses. And
again, the present alternative has few disadvantages.
