[SOLVED] chkconfig [service name] not displaying any return values.

Grtyop · 09-09-2013, 03:55 AM

In the chkconfig man page --> " When chkconfig is run with only a service name, it checks to see if the service is configured to be started in the current runlevel. If it is, chkconfig returns true; otherwise it returns false. "

But when I execute chkconfig xinetd for example , there is no output. xinetd is already on under chkconfig.

False output refers to no output ?

Thanks.

do as follows:

chkconfig --list xinetd

"chkconfig xinetd" outputs nothing

Quote:

chkconfig --list [name]
chkconfig --add name
chkconfig --del name
chkconfig [--level levels] name <on|off|reset>
chkconfig [--level levels] name

please check manual for details

Okay thanks, so the wording in the man page is kinda wrong ? :O

Nope. You need to check the commands exit status.

The "returns true; otherwise it returns false" does not actually mean the command will output the words true or false.

"chkconfig" name output nothing but does set the result code (As the man indicates)

Code:

 [root@maplepark ~]# chkconfig smb && echo "configured to be on"
configured to be on
[root@maplepark ~]# chkconfig virt-who && echo "configured to be on"
[root@maplepark ~]#
