File System table or FSTAB refers to system configurations which are usually used on a Linux environment. Sometimes users may have problems with adding spaces in mouth point path. This mainly happens because here various options are separated by a space.
Is known that / etc / fstab words are separated by spaces and it is not possible to put spaces in the path of the mount point.
This limitation is easily bypassed by typing " 040" instead of a space in the configuration file.
/dev/sda1 /mnt/first 40disk ext3 options 0 0
This simply means that we mount /dev/sda1 on /mnt/first disk
