mountpoint

Mount Point:

#lsblk The command lsblk by default will list all block devices in a tree-like format. Open your terminal and type the command as follows: $ lsblk The output is as follows: There are seven columns namely: NAME : This is the device name. MAJ:MIN : This column shows the major and minor device number. RM : This column shows whether the device is removable or not. Note in this example the device sdb and sr0 have their RM values equals to 1 indicating they are removable. SIZE : This is column give information on the size of the device. For example 298.1G indicate the device is 298.1GB and 1K indicate the device size is 1KB. RO : This indicates whether a device is read-only. In this case all devices have a RO=0, indicating they are not read only. TYPE :This column shows information whether the block device is a disk or a partition(part) within a disk. In this example sda and sdb are disks while sr0 is a read only memory (rom). MOUNTPOINT : This column indicates mount point on which the device is mounted. List All Devices The default option does not list all empty devices. To view these also use the command as follows: $ lsblk -a This option will list all devices including empty ones. List Device Permissions and Owner The command lsblk can also be used to list the ownership of a particular device as well as the group the mode. This can be achieved as follows: $ lsblk -m List Specific Devices It is possible also to get information about a specific device only. This can be achieved by specifying the device name after the option supplied to lsblk. For example you would be interested to know your hard drive size in bytes. You can accomplish this by running the command as follows: $ lsblk -b /dev/sda or if you prefer: $ lsblk --bytes /dev/sda

2. df command In linux df command is used to display the amount of total and free disk space available on the mounted file systems. Using df options you can find used blocks, inodes and free space available in the file system. In Linux, there are lots of others tools like ncdu, crusader, KDiskFree, Gnome Disk utility to monitor the disk usage. In this article, we show you a nice option of df command to display mount point using specific filesystem type. 1) Default and human readable Default and human readable format shows used space, available free space, percentage of space used and mount path. # df Filesystem 1K-blocks Used Available Use% Mounted on /dev/hda2 9448100 3549668 5418492 40% / # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 7.6G 1.9G 5.4G 26% / tmpfs 478M 0 478M 0% /dev/shm 2) Display Filesystem Type df command have an option -T shows fileystem type of mounted file system. Below ouput shows /dev/sda7  and /dev/sda8 on ext4 filesystem. # df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/sda7 ext4 10079084 6468168 3098916 68% / /dev/sda8 ext4 5039616 2948128 1835488 62% /home 3) Display Mount point on specific filesystem You can use -t followed by filesytem type (say ext3, ext4, nfs) to display respective mount points. For examples below df command display all nfs mount points. # df -HP -t nfs
