I normally use ; to combine more than one command in a line, but some people prefer &&. Is there any difference? For example, cd ~; cd - and cd ~ && cd - seems to make the same thing. What version is more portable, e.g. will be supported by a bash-subset like Android’s shell or so?
If previous command failed with
;the second one will run.But with
&&the second one will not run.This is a “lazy” logical “AND” operand between operations.
