Linux Shell Scripting Cookbook - Third Edition

How to do it...

The /etc/fstab file defines how disks are to be mounted and what options are supported.

The Linux system records when a file is created, modified, and read. There is little value in knowing that a file has been read, and updating the Acessed timestamp every time a common utility like cat is accessed gets expensive.

The noatime and relatime mount options will reduce disk thrashing:

    $ cat /dev/fstab
    /dev/mapper/vg_example_root  /    ext4 defaults,noatime  1 1
    /dev/mapper/gb_example_spool /var ext4 defaults,relatime 1 1
