btrfs (B-tree file system) is a newer file system designed to address the needs of modern storage systems. It's been described as the "next generation file system" for Linux, and it includes several advanced features not found in ext4 (which might make you wonderwhether to use ext4 or b...
Daemons perform certain actions at predefined times or in response to certain events. There are many daemons that run on a Linux system, each specifically designed to watch over its own little piece of the system, and because they are not under the direct control of a user, they are effec...
@Telemachus if you need to avoid TOCTOU, at least on Linux systems you can just open() the file in TOC (the open() result then becomes the check for file-exisence), then use this descriptor in TOU. This way even if file does not exists anymore at TOU, you still can access it thr...
Are GFS2 file systems over 25 TB supported? Is it possible to use Ext3 for file systems 16TB and above on Red Hat Enterprise Linux? I cannot create a 20TB file system in Ext4 or Ext3. Is it possible to use Ext3 for a very large file system (16 TB and above)? If not, which...
In Linux/Unix, everything is a file. Regular "files", directories, and even devices are files. Every file has an associated number called the file descriptor (FD), a non-negative integer that starts at 0. Your terminal/console is a device, and therefore has a file descriptor associated ...
If you are using the cron table for the first time, it will ask you to choose your preferred text editor. I will recommend using the nano: Once done,go to the end of the file in nanousingAlt + /and paste the following line into the file: ...
You can see that “file1″and “hlink1” have the same inode number. Truthfully, hard links are possible because of inodes. A hard link does not create a new file. It only provides a new name for the same data. In older versions of Linux, it was possible to hard link a directory...
As a server administrator or Linux desktop user or anyone who is new to Linux, understanding about/etc/fstabfile in Linux and how to debug fstab issues are very important. Fstab is afilesystemtable used by the kernel during boot time to mount the file system. To put it in simple terms,...
FAT file systems are a common partition type in PCs and Mac devices. Today, we'll be exploring how many types of FAT file systems are there and what are their differences. We’ll also compare it to NTFS and establish the differences between multiple FAT file systems, such as FAT32, FAT...
