Describing Linux fstab filesystem table file

When using Linux you will needed to change some options on your file systems. Getting acquainted with fstab can make the whole process a lot easier, and it’s much easier than you think. The configuration file /etc/fstab contains the necessary information to automate the process of mounting partitions. In a nutshell, mounting is the process where a raw (physical) partition is prepared for access and assigned a location on the file system tree (or mount point). The file FSTAB contains descriptive information about the various file systems. fstab is only read by programs, and not written; it is the duty of the system administrator to properly create and maintain this file. Each filesystem is described on a separate line; fields on each line are separated by tabs or spaces. Lines starting with ‘#’ are comments. The order of records in fstab is important because fsck, mount, and umount sequentially iterate through fstab doing their thing. This is an example of a fstab content There are total six columns in the fstab file separated by spaces or tabs. Each column holds different information about the device. For adding any new device add a fresh row. Each row stands for a partition or removable device in the system.
