66-all

This command handles all services for any tree defined for the current user of the proccess at once.

Interface

    66-all [ -h ] [ -z ] [ -v verbosity ] [ -l live ] [ -T timeout ] [ -f ] [ -t tree ] up|down|unsupervise

Any enabled tree—see 66-tree -E—or a specific one passed with the -t option, and an already running scandir will be processed. It is a safe wrapper around 66-start and 66-stop.

Exit codes

  • 0 success
  • 100 wrong usage
  • 111 system call failed

Options

  • -h : prints this help.

  • -z : use color.

  • -v verbosity : increases/decreases the verbosity of the command.

    • 1 : only print error messages. This is the default.
    • 2 : also print warning messages.
    • 3 : also print tracing messages.
    • 4 : also print debugging messages.

  • -l live : changes the supervision directory of service to live. By default this will be %%livedir%%. The default can also be changed at compile time by passing the --livedir=live option to ./configure. An existing absolute path is expected and should be within a writable and executable filesystem - likely a RAM filesystem—see 66-scandir.

  • -T timeout : specifies a general timeout (in milliseconds) passed to 66-start or 66-stop. By default the timeout is set to 0 (infinite).

  • -f : fork the process and lose the controlling terminal. This option should be used only for a shutdown process.

  • -t tree : only handles service(s) for tree.

  • up : sends an up signal to every service inside any tree processed by the command.

  • down : sends a down signal to every service inside any tree processed by the command.

  • unsupervise : Bring down all services contained into the tree and remove the corresponding directory of the service from the scandir.

Initialization phase

In case up was passed as option, 66-all will automatically launch 66-init to initiate all services of the trees processed by the command. As described above this means either any enabled tree for the user currently launching the process or just the tree passed with the -t option.
