littler is the first command-line interface for R and predates
Rscript. And it is (in my very biased eyes) better as it allows for piping as well shebang scripting via
#!, uses command-line arguments more consistently and still starts faster. It also always loaded the
methods package which
Rscript converted to rather recently.
littler lives on Linux and Unix, has its difficulties on macOS due to yet-another-braindeadedness there (who ever thought case-insensitive filesystems as a default where a good idea?) and simply does not exist on Windows (yet – the build system could be extended – see RInside for an existence proof, and volunteers are welcome!).
A few examples as highlighted at the Github repo:
This release updates two scripts I use all the time, and which were impacted by upstream changes in other packages they use. So
roxy.r will now use the previous version of roxygen2 if found in
~/.R/cache – a location only otherwise used by this script. Similarly,
rcmd.r needed an updated as rcmdcheck unexpectedly altered a function signature. A trivial
rchk.r caller script was added to call the mostful
rchk instance at rhub to test a source package.

Changes in examples
roxy.rnow uses cached copy of roxygen2 version 6.0.1 (if available) as the current version 6.1.0 changed behaviour.
rcc.rwas updated as the underlying rcmdcheck changed parameter order.
A new simpler wrapper
rchk.rwas added to use RHub with the

CRANberries provides a comparison to the previous release. Full details for the littler release are provided as usual at the ChangeLog page. The code is available via the GitHub repo, from tarballs and now of course all from its CRAN page and via
install.packages("littler"). Binary packages are available directly in Debian as well as soon via Ubuntu binaries at CRAN thanks to the tireless Michael Rutter.
Comments and suggestions are welcome at the GitHub repo.
