cmd :: Expression t -> [Expression t] -> Statement tSource
Create a simple command from expressions.
esed :: Monoid m => Identifier -> Bool -> Annotated mSource
Declare or assign an array to a sed command line that will use extended
regular expressions, checking for GNU or BSD sed. The Bool argument
determines whether to insert the declaration or not.
for :: (Monoid m, Integral i, Show i) => Identifier -> i -> i -> Annotated m -> Statement mSource
Perform a statement for integer values ranging from the first integral
parameter to the second, using seq.
A set statement that covers a few error handling options, setting
errexit, nounset and pipefail.
sudo_write :: Monoid m => Expression m -> Statement mSource
A statement that allows one to redirect output to a file as root. This is
what you might expect sudo echo x > privileged_file would do (though
that does not actually work).
