About

This is a SquashFS plugin for Midnight Commander. Having it installed, you could explore the content of your *.squashfs and *.sqfs files the same way you do with zip, 7z etc.

Notice: When you access some file via a vfs layer in mc, the file is extracted into a temp dir (in order of precedence: $MC_TMPDIR, $TMPDIR, /tmp). So, for example, it is not a very bright idea to browse into a big squashfs file inside some ISO image: the whole squash would be extracted into the temp dir.

Installation

The code is based on the unsquashfs tool. In Ubuntu it comes with squashfs-tools package.

Notice: Pathes used below are from Ubuntu. It might differ in your distro.

There are two relevant config files:

• global /etc/mc/mc.ext (since 4.8.29: /etc/mc/mc.ext.ini)
• local ~/.config/mc/mc.ext (since 4.8.29: ~/.config/mc/mc.ext.ini).

The global config is not loaded if the local one exists.

Config snippet for this script (check your mc version with F1 key):
