• Create or append files and directories to a squashfs filesystem (compressed using gzip by default):
  mksquashfs {{path/to/file_or_directory1 path/to/file_or_directory2 ...}} {{filesystem.squashfs}}
• Create or append files and directories to a squashfs filesystem, using a specific [comp]ression algorithm:
  mksquashfs {{path/to/file_or_directory1 path/to/file_or_directory2 ...}} {{filesystem.squashfs}} -comp {{gzip|lzo|lz4|xz|zstd|lzma}}
• Create or append files and directories to a squashfs filesystem, [e]xcluding some of them:
  mksquashfs {{path/to/file_or_directory1 path/to/file_or_directory2 ...}} {{filesystem.squashfs}} -e {{file|directory1 file|directory2 ...}}
• Create or append files and directories to a squashfs filesystem, [e]xcluding those ending with .gz:
  mksquashfs {{path/to/file_or_directory1 path/to/file_or_directory2 ...}} {{filesystem.squashfs}} -wildcards -e "{{*.gz}}"
• Create or append files and directories to a squashfs filesystem, [e]xcluding those matching a regular expression:
  mksquashfs {{path/to/file_or_directory1 path/to/file_or_directory2 ...}} {{filesystem.squashfs}} -regex -e "{{regular_expression}}"
