sqfstar: Create a squashfs filesystem (compressed using `gzip` by default) from an uncompressed tar archive.

sqfstar

$ sqfstar ${filesystem-squashfs} < ${archive-tar}

try on your machine

The command "sqfstar ${filesystem-squashfs} < ${archive-tar}" is using the "sqfstar" utility to create a squashfs filesystem from a tar archive.

Here's a breakdown of the command:

"sqfstar": This is the command itself, which is a utility used to handle squashfs filesystems.
"${filesystem-squashfs}": This is a placeholder for the name or path of the squashfs filesystem that will be created by the command. The actual value would be provided when running the command.
"<": This is a redirect symbol used in the command line interface to specify that input should be taken from a file or another source. In this case, it means that the standard input for the "sqfstar" command will be taken from the file specified by the next part of the command.
"${archive-tar}": This is another placeholder representing the name or path of the tar archive file that will serve as the input for the "sqfstar" command. Like the previous placeholder, the real value would be provided when executing the command.

In summary, the command takes a tar archive file (${archive-tar}) as input and uses the "sqfstar" utility to create a squashfs filesystem (${filesystem-squashfs}) from that archive.
