Editor to share with you how to use the Findmnt command under Linux. I hope you will get something after reading this article. Let's discuss it together.

The Findmnt command is used to find the mounted file system. It is used to list installed devices, which can also be mounted or uninstalled when needed, as part of the util-linux package.

Install findmnt

The findmnt command comes from the util-linux package and is installed by default in most distributions, such as Ubuntu,Fedora,Debian

Basic use

Copy the code

The code is as follows:

$aptitude search util-linuxi util-linux-Miscellaneous system utilities

$yum info util-linux

Basic use

The code is as follows: $findmnt

Lists mounted file systems by file type.

Copy the code

The code is as follows:

$findmnt-t ext4

Output Findmnt in df format can use the "- D" or "- df" options to create an output report in df format with free and used disk space.

Copy the code

The code is as follows:

$findmnt-DSOURCE FSTYPE SIZE USED AVAIL USE% TARGETdevtmpfs devtmpfs 994.2M 0 994.2M 0% / devselinuxfs selinuxfs 000-/ sys/fs/selinuxtmpfs tmpfs 1001.5M 68K 1001.4M 0% / dev/shmtmpfs tmpfs 1001.5M 724K 1000.8M 0% / runtmpfs tmpfs 1001.5M 01001.5m 0% / sys/fs/cgroup/dev/mapper/fedora-root ext4 6.5G 5.3G 811.6M 82% / tmpfs tmpfs 1001.5M 60K 1001.5m 0% / tmp/dev/ Sda1 ext4 476.2M 107.7M 339.6M 23% / boot

Raw output if you prefer raw style output, use the "- r" or "- raw" options.

Copy the code

The code is as follows:

Find the file system through the source device lookup, specify that the device path includes / does not include the "- S" option.

Copy the code

The code is as follows:

$findmnt-S / dev/sda1TARGET SOURCE FSTYPE OPTIONS/boot / dev/sda1 ext4 rw,relatime,seclabel,data=ordered

Find the file system through the mount point lookup, and specify that the directory includes / does not include the "- T /-target" option.

Copy the code

The code is as follows:

$findmnt-T / TARGET SOURCE FSTYPE OPTIONS/ / dev/mapper/fedora-root ext4 rw,relatime,seclabel,data=ordered

$findmnt-T / media/4668484A68483B47TARGET SOURCE FSTYPE OPTIONS/media/4668484A68483B47 / dev/sda5 fuseblk rw,nosuid,nodev,relatime,user_id=0
