unsquashfs:tldr:7434b
The command unsquashfs -ls ${filesystem-squashfs} is used to list the contents of a squashfs filesystem.
Here's a breakdown of the command:
-
unsquashfsis the command-line tool used to extract files from a squashfs filesystem. Squashfs is a compressed read-only file system commonly used in Linux-based systems. -
-lsis an option provided to theunsquashfscommand to specify that we want to list the files and directories present in the squashfs filesystem. It stands for "list". -
${filesystem-squashfs}is a placeholder that should be replaced with the actual path to the squashfs file you want to extract and view the contents of. This is the input file forunsquashfs.
So, when you run the given command, you are telling the unsquashfs tool to list the contents of the specified squashfs file.
For example, if you have a file named filesystem.squashfs in your current directory, you would replace ${filesystem-squashfs} with filesystem.squashfs like this:
unsquashfs -ls filesystem.squashfs
The command will then extract the squashfs file and display a list of all the files and directories present within it.
