Create a simple command from expressions.

esed :: Monoid m => Identifier -> Bool -> Annotated m

Perform a statement for integer values ranging from the first integral parameter to the second, using seq.

seqAZ :: Integral i => i -> i -> Statement t

Evaluate seq for the given arguments.

setSafe :: Statement t

A set statement that covers a few error handling options, setting errexit, nounset and pipefail.

sudo_write :: Monoid m => Expression m -> Statement m
