Well I managed to get the file created, I had to use visudo to create a custom file with my edits.

I'm testing it now to see if everything works.

Really? It doesn't let you just sudo a file in the dump directory? I wonder how they are enforcing that?

Yeah, not sure why it was having a hissy fit over it, but I've got a good working custom sudoer.d/god file now that can be used for what I have, and I can simply cp that into the appropriate folder and reset the perms on it (if required) to get everything working.

Thanks for the help guys!

@DustinB3403 said in Unix Command line - Printer Details:

Here is the completed command.

lpoptions -p <NAME> | grep -o "printer-make-and-model='Your Printer make and Model"

That outputs the exact detail I needed!

lpoptions -p SHCSL_209_ColorPrinter | sed -r "s/^.*(printer-make-and-model.*)'.*$/\1/g; s/'//g; s/printer-make-and-model=//g"

This will remove all the unnecessary text, printer-make-and-model=, and the single quotes.

Yeah I'm also able to just use lpoptions -p SHCSL_209_ColorPrinter | grep "'SHCSL_209_ColorPrinter'" and get what I need in a single line response.

Is there a reason that you are looking into Awk? Awk is a programming language that used to be popular for extension text processing in conjunction with BASH. But in the last decades, its use has fallen away and that is why you won't find examples of it. It's only used for very basic things now. Languages like Perl and Python supplanted it being easier to use, better known, more portable, and vastly more powerful. Awk is really a legacy tool today.

@DustinB3403 said in Tar gzip file compression calculation without decompressing the file:

@Pete-S So the simplest way I can think to explain this would be like this.

You have a network share which is relatively organized

You create a compressed tarball of any folder on that share and then move that tarball to offsite storage.

How would I realistically get a hash of that folder pre and post tar and compression and have it make sense? They aren't the same thing, even if they contain the same things.

@Pete-S said in Tar gzip file compression calculation without decompressing the file:

Is it safe to assume that the gzip file is correct when it is created?

This is what I'm looking to verify 🙂

I'm assuming that files are static during backup.

If you first of all run md5deep on all files in the folder, you'll create a textfile that contains md5 (or sha256 or what you want) signatures on every file in the folder. Place it into the folder so it ends up inside the backup and you'll always have the ability to verify any uncompressed individual file.

If you really want to verify your tar.gz file after it's created I think you have to decompress the files to a temporary folder, run md5deep on the files to compare them with the original file. What you really are testing is that the backup-compress-decompress-restore operation is lossless on every file. It should be by design, but if there is an unlikely bug somewhere it's technically possible that it might not be.

If you use the gzip compression with tar, gzip has a CRC-32 checksum inside that can be used to verify the integrity of the gzip file.

Or to be even more certain you can create an md5 signature of the entire gzip archive with md5sum or md5deep. Then you can always verify that the archive has not been corrupted.

If you ever need to restore the files you can verify the integrity of the restored files with the md5 you created on the original files, before you did the backup.

I am using fedora 22.

Fedora 31 is current. F22 is insanely ancient.

Placeholder

You almost had it. It should be...

find /Volumes -not -name something

rpcbind services is not required for NFSv4

Does that also prevent it from sleeping when the lid is closed?

The lid closed is powernap 🙂

So with further testing, a restart is required if the user is using their system, otherwise they'll continue to get the notifications.

@DustinB3403 said in lpadmin - remove printer with a space in the name:

Nevermind!

lpadmin adds spaces as underscores!

So with lpadmin -p I was able to find the list of printers.

lpadmin -p
Accounting_Printer

And with lpadmin -x Accounting_Printer was able to remove the printer!
Removed Accounting_Printer

Good to know for central administration of Apple devices. What are you using right now?

ARD and Unix cli

@DustinB3403 said in OSX Unix Using Brew to install software remotely:

So I can just unpack the dmg file, and have an Copy job, copy the application to the Applications folder for any user. As my admin user account. All via Apple Remote Desktop.

This works without issue.

What I am trying to do is avoid having to locally download the app at all, unpack it and then have a Copy job to run. I'd like to streamline the process.

That's what the script is doing already. Making your own "sudo friendly" script for your install might make sense.

The issue is there is no way AFAIK without adding my local admin account to this group.

Which is more work than it may be worth since the existing solution works but is annoying.

Traditionally TrueOS has been a good desktop.
