# 66-intree
This command displays information about trees.
## Interface
```
66-intree [ -h ] [ -z ] [ -v verbosity ] [ -l live ] [ -n ] [ -o name,init,enabled,... ] [ -g ] [ -d depth ] [ -r ] tree
```
## 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](66-scandir.html).
- **-n** : do not display the field name(s) specified.
- **-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 the *service* as a hierarchical graph instead of a list.
- **-d** *depth* : limits the depth of the dependency list visualisation; default is 1. This implies **-g** option.
- **-r** : shows the dependency list of *tree* in reverse mode.
***(!)*** If tree is not specified *66-intree* will display information about all available trees for the current owner of the process. In this case, It displays first the trees which is not marked enabled in alphabetical order then the trees marked enabled in start order.
## Valid fields for -o options
- *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.
- *start* : displays the list of *tree*(s) started before.
- *current* : displays a boolean value of the current state.
- *allowed* : displays the list of allowed user to use the *tree*.
- *symlinks* : displays the target of *tree*'s symlinks.
- *contents* : displays the contents of the *tree*.
## Command and output examples
The command `66-intree boot`, run as root user, on [Obarun](https://web.obarun.org)'s default system displays the following where *boot* is the tree used to properly boot the machine:
```
Name : boot
Initialized : yes
Enabled : no
Starts after : None
Current : no
Allowed : root
Symlinks : svc->source db->source
Contents : 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](66-init.html) tool.
The field *Enabled* reveals the state of the tree—see [66-tree -E](66-tree.html).
The field *Starts after* reveals the start process order if the *tree* is enabled, meaning which *tree* is started before the current one.
The field *Current* tells you if the tree is the current one or not—see [66-tree -c](66-tree.html).
The field *Allowed* gives you a list of user(s) allowed to handle the tree—see [66-tree -a|d](66-tree.html).
The field *Symlinks* tells you if the current live state point to the *source* or the *backup* of the *tree*. Every use of [66-enable](66-enable.html) tool create a automatic backup of the tree for `classic`,`bundle` or `atomic` service(s). A symlink pointing to *backup* mean that you have enabled a service without starting it. Right after a boot, each tree should point to *source*.
The field *Contents* 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 contents -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
```
