supervisor (1) - Linux Man Pages

Node Supervisor is used to restart programs when they crash.

It can also be used to restart programs when a *.js file changes.

Usage:

  supervisor [options] <program>

  supervisor [options] -- <program> [args ...]
Required:

  <program>

    The program to run.
Options:

  -w|--watch <watchItems>

    A comma-delimited list of folders or js files to watch for changes.

    When a change to a js file occurs, reload the program

    Default is '.'
-i|--ignore <ignoreItems>

    A comma-delimited list of folders to ignore for changes.

    No default
-p|--poll-interval <milliseconds>

    How often to poll watched files for changes.

    Defaults to Node default.
-e|--extensions <extensions>

    Specific file extensions to watch in addition to defaults.

    Used when --watch option includes folders

    Default is 'node,js'
-x|--exec <executable>

    The executable that runs the specified program.

    Default is 'node'
--debug

    Start node with --debug flag.
--debug-brk[=port]

    Start node with --debug-brk[=port] flag.
--harmony

    Start node with --harmony flag.
-n|--no-restart-on error|exit

    Don't automatically restart the supervised program if it ends.

    Supervisor will wait for a change in the source files.

    If "error", an exit code of 0 will still restart.

    If "exit", no restart regardless of exit code.
--force-watch

    Use fs.watch instead of fs.watchFile.

    This may be useful if you see a high cpu load on a windows machine.
