comment Finding out what DNS server are being used
It could also mean that your router is configured to not answer your queries, which is fairly common in corporate environments, so if you bought a router from eBay and repurposed it for home use you really want to reconfigure it.

No, it means either the router has cached that the hostname you're looking up doesn't exist, or that the router doesn't have any referrers configured.

comment Dangers of using rm command with variables
@SimplePi: yes, that is what I'm suggesting, in addition to sanity checking the value of $DATE after you establish it.

comment Get Linux architecture from /proc filesystem
The OP specifically asked for something not uname; something reading from the /proc filesystem.

comment What is “Localhost” binding in DNS forwarder in pfSense?
Anything that depends on it will break. It's generally not a good idea to do that unless you have a deep understanding of the system in question.

Look in /var/log/maillog for messages indicating the mail being sent, accepted, rejected, whatever.

comment RHEL Jenkins email notifications failing
Outlook is not a mail server, it's just a reader. You need something like Exchange or sendmail. If you don't know, you most likely don't have one, since you would have had to install it yourself.

Is your Windows system running a mail server?

comment On the command line, how do you find out where apps are installed?
@RomeoNinov if a common program such as vim is being invoked by a script, then the OP has modified his/her system to do so, and will know what modifications he/she has made, so again, that object is irrelevant.

comment Install Mesa3D on Debian - LIBDRM not found by configure autoconf
You're correct - I was getting confused in re-reading the initial post. You do, however, need to install development packages for the DRM libraries. I'll modify this answer to reflect that shortly.

comment Using rpm/grep to check whether multiple services are installed - as one liner?
True, but I'm assuming the OP can handle any differences of that nature, as that ability seems implicit in the question itself.

comment Installing Octave on CentOS - incompatible BLAS library error
What happens if you use F77=g77 instead? (You may have to install the compat-gcc-34-g77 (or similar name for your version of CentOS) package.)

Do you have the -dev package installed for opengl, gles1, or gles2?

comment Why doesn't `find` find these files
Yeah - however you want to protect the asterisk from being interpreted as a shell glob.

SSH to the destination host and type "umask"

comment How to NOT preserve permission when using scp
That command should definitely not be preserving permissions. What is the umask on the destination side? Can you confirm that it preserves ownership and permissions after a successful copy? Not that ownership may be preserved simply because you're using the current owner as the destination user account, not because of scp.

comment How to NOT preserve permission when using scp
What is the command you're using now? By default, scp doesn't preserve permissions from the source unless you tell it to.

comment Script to ensure that only one instance of Oracle is running
Look, you said yourself you're a DBA. Which means you're not a systems admin. I am, and I'm telling you, the login in this script is a problem. If you don't want to fix it, fine, but it will continue to break, and it will do so on more and more of your environments, so if you choose to do nothing, on your head be it.

comment Script to ensure that only one instance of Oracle is running
The issue is definitely in the script logic. You've just gotten unreasonably lucky that it actually works elsewhere.

comment how to login by ssh when default shell is wrong
Nevermind, you answered my question already. Do you have physical access to the server?
