If the file *could* grow to 1.8T, is that some kind of software limit, or does it imply that the machine actually has at least 1.8T? -- Beartooth Staffwright, Not Quite Clueless Power User Remember I know little (precious little!) of where up is. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

I knew what you meant. :-) Sometimes I feel it is unfortunate that the term "directory" is used when a "folder" would seem better in some cases. When you walk into a building you see a sign on the wall with a list of companies and what floor they can be found on. That sign is often called a "directory" and an "entry" on the directory indicates where the company is located. From that point of view an inode is an entry in a "directory" (inode table) with pointers (and other info) to where a file or "folder" can be found in storage. -- The key to getting good answers is to ask good questions. ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

Well, of course you know what an inode is and I didn't mean to suggest otherwise. I just think that saying it's like a directory entry (even with the qualification) is not helpful, especially as the term 'directory entry' crops up in this context and means something different. Put it down to my many years teaching this stuff but I'm always thinking about how the student might misunderstand something. poc ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

Sometimes I offer to provide a bash loop. Now ESA has a system called SNAP, programmed in Java, which can greatly reduce the number of mouse clicks in certain image processing workflows. You can connect operation icons using a GUI to produce an image processing workflow graph. Internally the system has a graph processing facility that splits large images into tiles and loops through the individual pixels, Users only need to select files in the GUI, fill in some forms for parameters and click on "Run".

IOW, it's a reasonable thing to do, given that old evils like dependency hell are pretty well gone. Good. All hail the developers!

But anyway, there's > your storage. It's my wife's previous machine, a System76 PC from several years back. (She thinks five to eight years.) Being from them, it arrived with Ubuntu (only, afaik). But I had so much trouble installing Fedora (trouble I had not had with an early System76 netbook) that I had to call a friend here, who came and did the install for me. All I can think of, and it seems unlikely, is that System76 might for some reason have started with a Windows machine, not bare metal. Maybe that's why. > It appears like you took a large hard drive and set it up for some > backup system, but I have no idea what one would work like that. I don't know what the friend did. The whole PC is now a backup; so I'd have no hesitation to DBAN it, install F32, and recopy data from my present #1 machine. I did think it seemed to have surprisingly little storage when I did that df -h; but if I understand better now, that 1.7T is real -- and, I hope, available for other uses. Is that so?

Wiping it or not is up to you, but a new install will be happier on a clean partition (or in fact several partitions in order to keep /home separate from root). However AFAIK the standard Fedora installer will do this for you. poc ___ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org

"ls -a /.snapshots" (It's plural...) # ls -a /.snapshots . .. alpha.0 lost+found I should have said "ls -l". I'm just curious what that is. Can you do "file /.snapshots/alpha.0" and if it's a directory, do "ls -la /.snapshots/alpha.0""? To find out how it's getting mounted, do "mount | grep snapshot" and "cat /etc/fstab".

So I burned a medium for F32 netinstall, and booted from that. As usual, I missed some boneheaded thing, and couldn't get Anaconda to accept any manual partitioning I tried; so I eventually just let it go automatic. It finished all right, and I'm adding apps. Beforehand, last night and this morning, I had copied my whole home directory to a thumb stick. Then this morning I merged it into the home directory of my #1 machine, which I'm using now. And I'm in process of merging it into #3. When that's done, I'll copy it back, knowing it works.
