EXT2 Explorer

Explore EXT2 File System with the convenience of your web browser!

The project aims to create a program that will take an EXT2 File System Parition and print certain information from it. Even though the program should work with a proper EXT2 partition, it is highly recommended to use this program only with a toy/dummy EXT2 partition. To this end it is recommended to create a parition within a file.

Steps to create an EXT2 partition within a file.

$ # The partition will be 128MB in size & minimum unit for data will be 1024 bytes.
$ # Create an "partition"
$ dd if=/dev/zero of=linux.ex2 bs=1024 count=131072

$ # Create the filesystem
$ mke2fs linux.ex2

$ # Mount the File System to a path.
$ sudo mkdir /mnt
$ mount linux.ext2 /mnt

$ # Unmount the File System.
$ sudo umount /mnt

How to use the program

The code starts a web server to which point the location of the file system and then press enter. This will redirect us to a page with details from the FS.

$ go run main.go
Adding handler functions...
Starting web server at port 8080...

Using browser go to http://localhost:8080, and a simple page with a form should display saying FS Path:______________. Enter the location of the file system in the box provided and hit enter.

This should create the sample output as show below.
