    • Oracle Linux – How to create /dev/zero after accidentally deleted

    in Linux

    APPLIES TO:

    Linux OS – Version Oracle Linux 7.0 to Oracle Linux 9.0 [Release OL7 to OL9]

    Linux x86_64 on Oracle Public Cloud

     

    GOAL:

    Create the character device /dev/zero which was deleted by error.

    This is not an essential character device for Linux to work properly, is mostly used to create dummy files and wipe out disks

     

    Symptoms

    [root@alejanarol7 ~]# dd if=/dev/zero of=./myfile.out bs=1M count=100 status=progress
dd: failed to open ‘/dev/zero’: No such file or directory
 
[root@alejanarol7 ~]# ls -l /dev/zero
ls: cannot access /dev/zero: No such file or directory

     

    SOLUTION:

    After /dev/zero was deleted by mistake now we need to create it.
