🦑Mounting disk images and access to files on them on linux:

How to view information about images to mount?
How to determine the file system of an image ?

1) You can use the file command to analyze which file system is used in files that are disk images.

An example of checking the test.image file :

file /mnt/disk_d/test.image

/mnt/disk_d/test.image: ISO 9660 CD-ROM filesystem data 'ARCH_202010' (bootable)

This is an ISO image.

2) An example of analyzing the disk.ntfs image :

file /mnt/disk_d/disk.ntfs

/mnt/disk_d/disk.ntfs: DOS/MBR boot sector, code offset 0x52+2, OEM-ID "NTFS ", sectors/cluster 8, Media descriptor 0xf8, sectors/track 63, heads 255, dos < 4.0 BootSector (0x0), FAT (1Y bit by descriptor); NTFS, sectors/track 63, physical drive 0x80, sectors 15654911, $MFT start cluster 786432, $MFTMirror start cluster 2, bytes/RecordSegment 2^(-1*246), clusters/index block 1, serial number 06258074758071a05; contains bootstrap BOOTMGR
As you can see, this is an image with the NTFS file system.

3) Checking the rootfs.sfs image :

file /mnt/disk_d/rootfs.sfs

/mnt/disk_d/rootfs.sfs: Squashfs filesystem, little endian, version 4.0, zstd compressed, 625010200 bytes, 58466 inodes, blocksize: 262144 bytes, created: Sat Jun 6 08:14:32 2020
This is a Squashfs file system image.

4) Analysis of the ext3-img-kw-1.dd image :

file /mnt/disk_d/ext3-img-kw-1.dd
