Bash/sh - difference between && and ;

Question

I normally use ; to combine more than one command in a line, but some people prefer &&. Is there any difference? For example, cd ~; c

Answer 1

Commands separate by ; are executed sequentially regardless of their completion status.

With &&, the second command is executed only if the first completes successfully (returns exit status of 0).

This is covered in the bash manpage under Lists. I would expect any Unix-like shell to support both of these operators, but I don't know specifically about the Android shell.
