filesystems

问题 Since macOS 10.15 (Catalina), a volume, as the user sees it, may actually be comprised of multiple volumes, such as the System and the Data volume. I'm writing a tool that needs to identify these volumes separately because when using specific file operations, such as searchfs and fts_read , which do not cross such volume boundaries, I need to understand which volumes belong together, so that, when the user wants to search a system volume, I know to include both the "System" and its "Data"

问题 Is there a way to add a "tag" (add a unique metadata/identifier) to a CSV file without affecting the contents or ability to read/write the file? I am using Python, but I don't think the language matters here. 回答1: Just add comment lines that you can parse later. #Creator:JohnSmith #Date:.... #Columns:id,username,... 1,JohnSmith 2, .. 回答2: This would be compliant with W3C embedded metadata format: http://www.w3.org/TR/tabular-data-model/#embedded-metadata #publisher,W3C #updated,2015-10-17T00

问题 I need to create a very high number of files which are not very large (like 4kb,8kb). It's not possible on my computer cause it takes all inodes up to 100% and I cannot create more files : $ df -i /dev/sda5 Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda5 54362112 36381206 17980906 67% /scratch (I started deleting files, it's why it's now 67%) The bytes-per-nodes are of 256 on my filesystem (ext4) $ sudo tune2fs -l /dev/sda5 | grep Inode Inode count: 54362112 Inodes per group: 8192
