How to Restore Deleted Tmp Directory in Linux

Every system has a /tmp directory that is used for temporary storage of files and data. It is generally used by applications and scripts to create lock files, temporary storage of data, files required to run the program currently and delete later on when program is closed. Its contents are automatically deleted when you boot or shutdown your Linux system, as a part of system administration. However, if you delete these files when your program is running, it may crash your program. So you have to be very careful before deleting this /tmp folder. If you have multiple users working on your system, it can even disturb their activities and sessions.

How to Restore Deleted Tmp Directory in Linux

Before we proceed, you need to ensure that the /tmp directory must belong to the root user, and you should modify the permissions of this directory such that all users are able to access it.

For this purpose, you can run the following commands.

$ sudo mkdir /tmp 
$ sudo chmod 1777 /tmp
OR
$ sudo mkdir -m 1777 /tmp

In the above command we use the permission 1777 to specify that every body (owner, group and others) can access its contents but only owner can delete it. This is done using the sticky bit ‘t’ by settings its value as 1.

Run the following command to check its permissions.

$ ls -ld /tmp
