Although we encourage you to embrace the new fswatch behaviour and update your scripts, we provide a
     little wrapper called fswatch-run which is installed alongside fswatch which lets you use the legacy
     syntax:

           $ fswatch-run path [paths] program

     Under the hood, fswatch-run simply calls fswatch -o piping its output to xargs.

     fswatch-run is a symbolic link to a shell-specific wrapper.  Currently, ZSH and Bash scripts are pro-
     vided.  If no suitable shells are found in the target system, the fswatch-run symbolic link is not cre-
     ated.
