Question

Can’t find information on how to print out documentation on android shell commands while in the shell. Something along the lines of

help ls

Answer 1

The command help got stripped for most (if not all) commandline tools.

The only thing I can tell you is how to find out about the functionality of all the tools or better where you can find the sources and look at each of their code.

Here you can find the commandline tools used in Android. Git source browser: system/core/toolbox

Now looking at the code of the ls command I can tell you for example that it supports following switches.

• -l long list
• -s list sizes
• -R list recursively
• -d list directories
• -a list all

You can try to find that information in the source code of the commands you need.

Hope it helped.
