mount - Command to mount partitions.

====Examples====
----

Mounts /dev/sdb2 to /mnt/[dir], you would have to create a directory in the /mnt/ directory
mount /dev/sdb2 /mnt/[dir]

Unmount:
umount /dev/sdb2

To view all mounts for further information:
mount
mount | grep -i /dev/

$ mount | grep /dev/
tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev)
devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000)
/dev/nvme0n1p2 on / type xfs (rw,relatime,attr2,inode64,noquota)
mqueue on /dev/mqueue type mqueue (rw,relatime)
hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime)
/dev/nvme2n1p1 on /home/ec2-user type ext4 (rw,relatime,data=ordered)
/dev/nvme1n1p1 on /var/log/important_app_logs type ext4 (rw,relatime,data=ordered)
/dev/nvme2n1p2 on /home/ardika type ext4 (rw,relatime,data=ordered)

=====Real world example=====
----

Sometimes you need to restore files from a previous snapshot. If you create a new volume from a previous snapshot, if you attach it to the original machine it came from you may run into problems when you try to mount it because of duplicate UUIDs.

$ mount /dev/nvme1n1p1 /disk
mount: /disk: wrong fs type, bad option, bad superblock on 
/dev/nvme1n1p1, missing codepage or helper program, or other error.

To get around this, you can use -o flag to specify options. Options are followed by a comma sperated string of options.
mount -o nouuid /dev/nvme1n1p1 /path/to/mount

OR you can do this:
mount -t ext4 /dev/nvme1n1p1 /path/to/mount

====Using Mount for [[Fstab|/etc/fstab]] Testing====
----

Once you have made a new entry in /etc/fstab, you can test if the automatic mount will be successful by running the [[Mount|mount]] command:
$ sudo mount -a

-a, --all
: Mount all filesystems (of the given types) mentioned in fstab (except for those whose line contains the noauto keyword). The filesystems are mounted following their order in fstab. Be sure to unmount the file system first before running it or else you will get an error saying "already mounted" or something like that.
