What is lost+found directory on Linux?
Many times while working on Linux system we come across the "lost+found" directory.
So what is this directory? What is use of this directory? Let's try to understand it.
"lost+found" directory on Linux Server
/lost+found directory can be accessed by “root” user on Linux Server
Do sudo su - and become root user
This directory contains recovered bits of corrupted files here
Let’s understand with some scenario
Sometime power off of Linux server happen abruptly, and it might be possible that some data writing operations are in progress on server.
Now, when we restart our Linux Server next time, the Linux FileSystem will do "FileSystem Check" with fsck command and all corrupted data / files will be placed in "lost+found" directory
fsck command on Linux
If we check the man page of "fsck" command, we will find that, it is mainly used for repairing various Linux File System
