sleep is a very popular command and we can start sleep from 1 second:
# wait one second please
sleep 1
but what the alternative if I need to wait only 0.1 second or between 0.1 to 1 second ?
sleep 0.XXX works fine , but on solaris sleep 0.1 or sleep 0.01 - illegal syntax
In centos how do you answer yes automatically for yum install so that it is an unassisted install?
I modified /etc/fstab.
I verified the new devices and I can mount them with the mount command.
How may I validate the modifications made to /etc/fstab ?

Can I nohup/screen an already-started process?
On Unix (specifically, Linux), I've started a job in a regular ssh->bash session. I'd like to leave work soon, but I now realize that the job is going to take several hours.
If I had just started this job in screen, I could detach and go home. But I didn't.
Is there any way to disconnect the job from its ssh session, so I can shut down my computer, (dropping the TCP connection and killing the ssh session), and yet have the program keep running?
I don't care about its output -- in fact, I redirected stdout to a file. I just want it to run to completion.
At our office, we have a local area network with a purely internal DNS setup, on which clients all named as whatever.lan. I also have a VMware environment, and on the virtual-machine-only network, I name the virtual machines whatever.vm.
Currently, this network for the virtual machines isn't reachable from our local area network, but we're setting up a production network to migrate these virtual machines to, which will be reachable from the LAN. As a result, we're trying to settle on a convention for the domain suffix/TLD we apply to the guests on this new network we're setting up, but we can't come up with a good one, given that .vm, .local and .lan all have existing connotations in our environment.
So, what's the best practice in this situation? Is there a list of TLDs or domain names somewhere that's safe to use for a purely internal network?
