Now let us check the method to access the list of file systems mounted to the system.
/proc/mountContains a list of all the file systems mounted on the system. We can cataccess this list by reading its contents using the command.
cat /proc/mounts
Output:
/etc/mtabIt also contains a list of all mounted file systems. We can cataccess this list by reading its contents using the command.
cat /etc/mtab
Output:
findmntThe command looks for mounted file systems and lists them in a tree-like format. If you don't want it to use a tree-like format, you can use -lthe -p parameter to list it.
findmnt
Output:
Use -tthe parameter to list only specific file systems.
findmnt -t ext4
Output:
dfThe command stands for disk free. It displays the total, used, and free disk size of the file system. -hThe - flag is used to display human readable sizes and -Tthe - flag is used to print the file system type.
df -hT
Output:
lsblkThe command finds mounted file systems and lists them in a tree format. Use -fthe -d parameter to get information about a file system.
