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}}"
