mcomp
Compares two files using mtools
TLDR
Compare a file on a DOS disk with a local file
$ mcomp [a:file.txt] [path/to/local_file.txt]
Compare a file from a disk image with a local file$ mcomp -i [path/to/disk.img] [::/file.txt] [path/to/local_file.txt]
SYNOPSIS
mcomp msdos-file local-file
DESCRIPTION
mcomp compares two files byte by byte, where the first file resides on a DOS-formatted disk (such as a floppy) accessible through mtools. It is functionally equivalent to using mcopy to copy the file locally and then comparing with cmp.This command is part of the mtools package, a collection of utilities for accessing MS-DOS disks from Unix without mounting them.
PARAMETERS
msdos-file
File on a DOS/floppy disk accessed via mtools.local-file
Local file to compare against.
INSTALL
sudo apt install mtools
sudo dnf install mtools
sudo pacman -S mtools
sudo apk add mtools
sudo zypper install mtools
brew install mtools
nix profile install nixpkgs#mtools
CAVEATS
The first argument must be a file accessible via mtools (e.g., on a DOS-formatted disk or disk image). On modern systems, using mcopy followed by cmp provides the same functionality and is more commonly used.
