If a unit's disabled but not masked, it can also be started as dependency of another unit.

This is on SL6. I haven't got my Sl7 VM fired up yet.
$ ps ax | grep dhc | awk -F "-lf " '{print $2}' | awk '{print $1}'
/var/lib/dhclient/dhclient-eth1.leases
Thank you!

Re: Sl 7: where did the dhcp.leases file go?
Square brackets around your searched for expression will allow you to
remove a pipe (no need to grep -v grep):
ps ax | egrep -e d[h]cp.'*\.lease'

Hi Tom,
Ah Ha! This on SL7:
$ ps ax | grep dhc | awk -F "-lf " '{print $2}' | awk '{print $1}' |
grep lease
/var/lib/NetworkManager/dhclient-43af4b20-79ba-4ca8-aa9f-c0cdec45e25f-eth0.lease
Thank you for helping me with this!

Hi Tom,

grep lease
/var/lib/NetworkManager/dhclient-43af4b20-79ba-4ca8-aa9f-c0cdec45e25f-eth0.lease
Thank you for helping me with this!

Okay, now I am getting scary!
$ grep dhcp-server-identifier $(ps ax | grep dhc | awk -F "-lf "
'{print $2}' | awk '{print $1}' | grep lease) | sort -r | sed -n 1,1p |
awk '{print $3}' | awk -F ";" '{print $1}'

The grep stand won't show itself, because it won't match the regexp.
Re: systemctl disable vs mask question
Hi all, It seems similar to chkconfig --add xyz and chkconfig --del xyz where xyz is a service to be managed by chkconfig or not, in init process.
