Pipes are not used.
+ When prepended by |:silent| the shell will not be set to
+ cooked mode. This is meant to be used for commands that do
+ not need the user to type. It avoids stray characters showing
+ up on the screen which require |CTRL-L| to remove. >
+ :silent let f = system('ls *.vim')

Note: Use |shellescape()| or |::S| with |expand()| or
|fnamemodify()| to escape special characters in a command
argument. Newlines in {expr} may cause the command to fail.
