title: The 66 Suite: 66-inservice author: Eric Vidal <eric@obarun.org> [66](index.html) [obarun.org](https://web.obarun.org) # 66-inservice This command displays information about services. ## Interface ``` 66-inservice [ -h ] [ -z ] [ -v verbosity ] [ -n ] [ -o name,intree,status,... ] [ -g ] [ -d depth ] [ -r ] [ -t tree ] [ -p nline ] service ``` ## 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. - **-n** : do not display the field name(s) specified. - **-o** : comma separated list of fields to display. If this option is not passed, *66-inservice* 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 *services* in reverse mode. - **-t** *tree* : only searches the *service* at the specified *tree*, when the same service may be enabled in more trees. - **-p** *nline* : prints the *nline* last lines from the log file of the *service*. Default is 20. ## Valid fields for -o options - *name* : displays the name of the *service*. - *intree* : displays the *service*'s tree name. - *status* : displays the status. - *type* : displays the *service* type. - *description* : displays the description. - *source* : displays the source of the *service*'s [frontend](frontend.html) file. - *live* : displays the *service*'s live directory. - *depends* : displays the *service*'s dependencies. - *extdepends* : displays the *service*'s external dependencies. - *optsdepends* : displays the *service*'s optional dependencies. - *start* : displays the *service*'s start script. - *stop* : displays the *service*'s stop script. - *envat* : displays the source of the environment file. - *envfile* : displays the contents of the environment file. - *logname* : displays the logger's name. - *logdst* : displays the logger's destination. - *logfile* : displays the contents of the log file. ## Command and output examples The command `66-inservice 00` run as root user on [Obarun](https://web.obarun.org)'s default system, displays the following, where *00* is a service contained in the tree boot: ``` Name : 00 In tree : boot Status : enabled, nothing to display Type : bundle Description : Set the hostname and mount filesystem Source : %%service_system%%/boot/mount/00 Live : %%livedir%%/tree/0/boot/servicedirs/00 Dependencies : 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 External dependencies : None Optional dependencies : None Start script : None Stop script : None Environment source : None Environment file : None Log name : None Log destination : None Log file : None ``` ***Note***: the *Optional dependencies* and *External dependencies* also displays the name of the tree where the service is currently enabled after the `colon(:)` mark if any: ``` External dependencies : dbus-session@obarun:base gvfsd:desktop Optional dependencies : picom@obarun:desktop ``` By default the dependency graph is rendered in the order of execution. In this example the `oneshot` system-hostname is the first executed service and `oneshot` *mount-cgroups* is the last one when it finishes. You can reverse the rendered order with the **-r** option. You can display the *status* and *depends on* field and only these fields of a *service* using the command `66-inservice -o status,depends -g <service>` connmand where the dependency list is diplayed as a graph: ``` Status : enabled, up (pid 938) 34652 seconds Dependencies : / ├─(933,Enabled,longrun) dbus └─(929,Enabled,longrun) connmand-log ``` You can display the status,log file and log destination and only these fields of a service using the command `66-inservice -o status,logdst,logfile -g dbus`: ``` Status : enabled, up (pid 933) 34852 seconds, ready 34852 seconds Log destination : %%system_log%%/dbus Log file : 2019-10-03 16:16:05.246991500 dbus-daemon[933]: [system] Rejected send message, 4 matched rules; type="method_call", sender=":1.3" (uid=1000 pid=1226 comm="connman-gtk --tray ") interface="net.connman.Technology" member="Scan" error name="(unset)" requested_reply="0" destination=":1.0" (uid=0 pid=938 comm="connmand -n --nobacktrace --nodnsproxy ") 2019-10-03 16:16:35.256146500 dbus-daemon[933]: [system] Rejected send message, 4 matched rules; type="method_call", sender=":1.3" (uid=1000 pid=1226 comm="connman-gtk --tray ") interface="net.connman.Technology" member="Scan" error name="(unset)" requested_reply="0" destination=":1.0" (uid=0 pid=938 comm="connmand -n --nobacktrace --nodnsproxy ") ```
