How to mount tmpfs?

To mount a tmpfs filesystem in Linux, you can use the mount command. Here’s how to do it:

Basic Command

sudo mount -t tmpfs -o size=SIZE tmpfs MOUNT_POINT

Parameters

• SIZE: Specify the size of the tmpfs filesystem (e.g., 100M for 100 megabytes, 1G for 1 gigabyte). If you want it to use all available memory, you can omit this option.
• MOUNT_POINT: The directory where you want to mount the tmpfs filesystem (e.g., /mnt/mytmpfs).

Example

1. Create a Mount Point:
   First, create a directory where you want to mount the tmpfs:

   sudo mkdir /mnt/mytmpfs

2. Mount the tmpfs:
   Now, mount the tmpfs filesystem:

   sudo mount -t tmpfs -o size=100M tmpfs /mnt/mytmpfs

3. Verify the Mount:
   You can verify that it has been mounted by using the df command:

   df -h /mnt/mytmpfs

Unmounting

To unmount the tmpfs, use the following command:

sudo umount /mnt/mytmpfs

Persistent Mount

If you want to make the tmpfs mount persistent across reboots, you can add an entry to the /etc/fstab file:

tmpfs   /mnt/mytmpfs   tmpfs   size=100M   0   0

This will ensure that the tmpfs is mounted automatically at boot time.
