Simple commands, pipelines and sequences
A simple command is a sequence of words, the first of which specifies the
command to be executed. A series of simple commands joined by `|' characters
forms a pipeline. The output of each command in a pipeline is connected to the
input of the next.
Simple commands and pipelines may be joined into sequences with `;', and will
be executed sequentially. Commands and pipelines can also be joined into
sequences with `||' or `&&', indicating, as in the C language, that the second
is to be executed only if the first fails or succeeds respectively.
A simple command, pipeline or sequence may be placed in parentheses, `()',
to form a simple command, which may in turn be a component of a pipeline or
sequence. A command, pipeline or sequence can be executed
without waiting for it to terminate by following it with an `&'.
