Question 9: Which Linux command is used to check file system integrity?

1. The command to display your current directory is "pwd" (print working directory). This command will show the absolute path of your current directory. 2. The command to change to a different directory is "cd" (change directory). You can specify the absolute or relative path to the directory you want to change to. 3. The maximum length of a file name on a Linux system varies depending on the file system used. Most modern file systems have a maximum limit of 255 characters for file names. 4. The command to create an empty file is "touch". For example, "touch myfile.txt" will create an empty file named "myfile.txt". 5. The command to delete files and directories is "rm" (remove). Use the "-r" option to delete directories and their contents recursively. Use the "-f" option to force the deletion without prompts. 6. The command to create directories is "mkdir" (make directory). For example, "mkdir mydir" will create a new directory named "mydir". 7. The directory in the FHS that stores programs that can only be executed by the root user is "/sbin" (system binaries). 8. The journaling mode that requires writing every file system change twice is "journal=writeback". This mode provides better performance but poses a higher risk of data loss in case of a power failure or system crash. 9. The Linux command used to check file system integrity is "fsck" (File System Consistency Check). This command can be used with various options to detect and fix errors on file systems. 10. The directory in the FHS that stores system configuration files is "/etc" (etcetera). This directory contains system-wide configuration files and scripts for various applications and services.
