Good read, thanks.

@flabbergastedFiltch said in Linux: Finding Files:

Yea, Scott's reply led me to:

find . -name "*\ " -print

Not a big leap.

Now I'm all the way down the rabbit hole of xargs, grep, and perhaps sed (?)

Using FreeBSD on EMC Isilon.

I have to do this a lot, but the creative way users name files is ever changing:
filename.
filename. [filename dot space]
file*name

Here's a sample of a real directory:

One or Two files (even 10) and I'd use mv to rename the files and remove the space or period or add extension, etc... This list represents just one folder out of a few hundred that have some gremlin preventing Windows NT Backup (don't ask) from taking a backup and deleting the originals.

Thanks for the reply and nudge. Now back to it after I change my Job Description on Linkedin to "Frustrated wannabe Software Developer".

As much as I like giant one liners, the best tool for this would be rename.

To remove a period just do

find . -type f -exec rename "." "" {} \;

You don't technically need to use find, but if the files span multiple directories it's easier.

Ya with a preallocated qcow2 I can get pretty close to raw speeds. No one is going to notice 10MB/s or even 20 in normal settings.

/proc/version usually has pertinent information across most systems.

Edit: I looked closer. It's just the OS name (RHEL/Ubuntu) and kernel version. Never mind.

That was in the original article.

And I quoted you without quoting you..... see what I did there, I switched a few words :P

To make what?

@JJoyner1985 said in UNIX: What Is a Tarball:

So, do you think the reason I am seeing a lot more gzip in use with tarballs is due to the familiarity of gzip and the negligible difference in the compression between it and bzip2? Basically, bzip2 doesn't make enough of an improvement with sufficient regularity to entice people to move away from gzip, or is there some other benefit to gzip that my training material hasn't covered?

That's correct. The difference between the two is generally small enough that people are not concerned. And lots of systems still don't have bzip2 installed by default so if you want scripts or whatever to work universally you often use gzip because you know that it is always there and predictable.

@scottalanmiller

While my main drive wasn't to get the rPi to learn some basic programming, I am hoping that it will help 'encourage' it.

I am planning to load Linux on my laptop as the primary, and take it from there. But I also am pushing myself to use the CLI more in the rPi than before..

@dafyre said in Linux: The Role of DRBD:

@scottalanmiller said in Linux: The Role of DRBD:

I added a header into the main topic list for that. But it is going to be later in the Advanced Topics, section. Oddly, I know of pretty much no standard Linux Administration tomes that cover DRBD. It's so core, very odd that it so often gets missed.

Could it be that most Linux Admin's don't know about it until they go searching for it? ...That's how I found out about it.

You would hope that the people writing the books would know, though!

Of interesting side note, the Linux md RAID system also implements Intel Matrix RAID and DDF (Disk Data Format) software RAID formats commonly used by consumer FakeRAID systems. Because of this, Linux md can sometimes convert FakeRAID into enterprise md RAID if you really know what you are doing :)

And by checking, he means learning and just happening to find it.

User of CentOS and Ubuntu servers myself. Mint is still top go-to for desktop, though there are interesting alternatives like ElementaryOS.

Linux is not always easy to learn, I just forget everything if it's not regularly used, especially CLI with their bazillion switches that no mere mortal can ever memorize. And moving between different distros where commands don't work exactly the same, Aptitude and Yum, etc.

Cool, but always challenging.

@scottalanmiller Ah, yes. That would be a more efficient way of doing it. I was too excited from finally gaining some understanding of mount point concepts, I didn't think though the best way to move the data. :)

@Dashrender said in Linux: Creating a Filesystem:

I'm assuming LVM will be covered separately - I'm trying to understand what it's purpose is versus just using mkfs.

It will be. And it is unrelated. mkfs and lvm do totally different things. Neither replaces the other in any way.

@johnhooks said in Linux: Looking for Large Folders with du:

I've always just used -h for human readable. I never realized -m would give you the MB size.

I have the "advantage" of having learned this stuff before the human readable flag was added ;)

@DustinB3403 said in Linux: Checking Filesystem Usage with df:

Will there be a topic on "managing inode in linux"

Yes, but it is going to go into an "Advanced Topics" section. Just as LVM and MD will have high level "normal" admin sections and eventually delve much deeper in advanced sections. I want to cover everything in a "normal admin" capacity like you would learn from the RHCE up front. Then go back and cover the nitty gritty details that other admin books don't. So it will basically take two passes but the hope is that the first pass will take you from "starting point" to "competent Linux Admin" then the second part will go where normal admin guides don't tread.

@tonyshowoff said in Linux: Zip and 7Zip:

Sorry if this was mentioned but I didn't see it directly mentioned for clarity:

If your compression is unavailable directly in tar (-J being essentially 7zip, my favourite), you can tar it first (without compression) and then compress the tar, this maintains both Unix metadata and also gives the benefit.

Also, if you compress something already compressed you won't get the best benefit, at least not when it comes to using something as powerful as LZMA/7zip.

I believe that that is mentioned in the tar article.
