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

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".

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

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

An inode is the chunk of metadata in the filesystem that describes a file. You could think of it simply as a directory entry, but it's more complicated than that. A block device is storage that accesses data in chunks. For example, hard drives can only access data in chunks of 512 bytes. You can't directly access a specific byte.
