Create a squashfs filesystem from a tar archive. More information: https://manned.org/sqfstar.

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

sqfstar filesystem.squashfs < archive.tar

• Create a squashfs filesystem from a tar archive compressed with gzip, and [comp]ress the filesystem using a specific algorithm:

zcat archive.tar.gz | sqfstar -comp gzip|lzo|lz4|xz|zstd|lzma filesystem.squashfs

• Create a squashfs filesystem from a tar archive compressed with xz, excluding some of the files:

xzcat archive.tar.xz | sqfstar filesystem.squashfs file1 file2 …

• Create a squashfs filesystem from a tar archive compressed with zstd, excluding files ending with .gz:

zstdcat archive.tar.zst | sqfstar filesystem.squashfs "*.gz"

• Create a squashfs filesystem from a tar archive compressed with lz4, excluding files matching a regular expression:

lz4cat archive.tar.lz4 | sqfstar filesystem.squashfs -regex "regular_expression"
