 1 | # What's on Lambda?
 2 | 
 3 | AWS Lambda runs Amazon Linux, a version of Red Hat. There's lots of
 4 | command-line tools installed in the environment. Here's a list. I've
 5 | excluded some boring programs.
 6 | 
 7 | These programs are already in `$PATH`; they don't count towards your
 8 | task's code size limit. So instead of including a dependency in your
 9 | archive, consider shelling out to one of them.
