66-intree(1)
# NAME
66-intree - Display information about trees.
# SYNOPSYS
66-intree [ *-h* ] [ *-v* _verbosity_ ] [ *-l* _live_ ] [ *-c* ] [ *-o* name,init,enabled,... ] [ *-g* ] [ *-d* _depth_ ] [ *-r* ] _tree_
# DESCRIPTION
*66-intree* displays detailed information about a _tree_.
# OPTIONS
*-h*
Prints this help.
*-v* _verbosity_
Increases/decreases the verbosity of the command.++
*1* : (Default) Only prints error messages.++
*2* : Also prints warning messages.++
*3* : Also prints 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
filesystem - likely a RAM filesystem. See *66-scandir*(1).
*-c*
enable colorization.
*-o*
comma separated list of fields to display. If this option is not passed,
*66-intree* will display all fields.
*-g*
shows the dependency list of _tree_ as a graph instead of list.
*-r*
Shows the dependency list of _tree_ in reverse mode.
*-d* _depth_
Limits the depth of the dependency list visualisation; defaults to 1.
This implies the *-g* option.
If _tree_ is not specified *66-intree* will display information about all
available trees for the current owner of the process.
## VALID FIELD FOR -g OPTION
*name*
Displays the name of the _tree_.
*init*
Displays a boolean value of the initialization state.
*enabled*
Displays a boolean value of the enable state.
*current*
Displays a boolean value of the current state.
*contains*
Displays the contents of the _tree_.
# COMMAND AND OUTPUT EXAMPLE
The command "66-intree boot", run as root user, on _Obarun_'s default system
displays the following where *boot* is the tree used to properly boot
the machine:
```
Name : boot
Initialized : yes
Enabled : no
Current : no
Contains : tty12 system-hostname mount-run populate-run mount-tmp
populate-tmp mount-proc mount-sys populate-sys mount-dev
mount-pts mount-shm populate-dev mount-cgroups 00
modules-kernel udevd udevadm devices-crypttab
system-hwclock system-random modules-system system-sysctl
system-fontnkey devices-dmraid devices-btrfs devices-lvm
devices-zfs system-Devices mount-swap all-Mount
system-fsck mount-fstab all-System mount-rw local-iptables
local-ip6tables local-loop local-sethostname local-time
local-authfiles local-tmpfiles local-rc local-dmesg all-Local
all-Runtime All
```
The field *name* gives you the name of the _tree_.
The field *Initialized* tells you if the _tree_ was initialized with "66-init" tool.
The field *Enabled* reveals the state of the tree -- see "66-tree -E".
The field *Current* tells you if the _tree_ is the current one or not -- see
"66-tree -c".
The field *Contains* gives you a list of all services enabled in the _tree_.
You can display the contents list as a graph and only these fields using
the command "66-intree -o contains -g boot":
```

```
For each service the first field found between *()* parentheses is the
corresponding pid of the service, the second one is the state of the
service, and next to it is the type of the service, separated by commas,
and finally the name of the service is displayed after the parenthesis ')'.
By default the dependency graph is rendered in the order of execution. In
this example the *classic tty12* is the first executed service and
*bundle All* is the last before it finishes. You can reverse the rendered order with
the *-r* option.
You can display the name and current field and only these fields for each
tree using the command "66-intree -o name,current":
```
Name : boot
Current : no
Name : docker
Current : no
Name : root
Current : no
Name : test
Current : yes
Name : user
Current : no
```
