unsquashfs


"OPTION -h"
SYNTAX: /bin/unsquashfs [OPTIONS] FILESYSTEM [files to extract or exclude (with -excludes) or cat (with -cat )]

Filesystem extraction (filtering) options:
    -d[est] <pathname>  extract to <pathname>, default "squashfs-root".
                This option also sets the prefix used when
                listing the filesystem
    -max[-depth] <levels>   descend at most <levels> of directories when
                extracting
    -excludes       treat files on command line as exclude files
    -ex[clude-list]     list of files to be excluded, terminated
                with ; e.g. file1 file2 ;
    -extract-file <file>    list of directories or files to extract.
                One per line
    -exclude-file <file>    list of directories or files to exclude.
                One per line
    -match          abort if any extract file does not match on
                anything, and can not be resolved.  Implies
                -missing-symlinks and -no-wildcards
    -follow[-symlinks]  follow symlinks in extract files, and add all
                files/symlinks needed to resolve extract file.
                Implies -no-wildcards
    -missing[-symlinks] Unsquashfs will abort if any symlink can't be
                resolved in -follow-symlinks
    -no-wild[cards]     do not use wildcard matching in extract and
                exclude names
    -r[egex]        treat extract names as POSIX regular expressions
                rather than use the default shell wildcard
                expansion (globbing)
    -all[-time] <time>  set all file timestamps to <time>, rather than
                the time stored in the filesystem inode.  <time>
                can be an unsigned 32-bit int indicating
                seconds since the epoch (1970-01-01) or a string
                value which is passed to the "date" command to
                parse. Any string value which the date command
                recognises can be used such as "now", "last
                week", or "Wed Feb 15 21:02:39 GMT 2023"
    -cat            cat the files on the command line to stdout
    -f[orce]        if file already exists then overwrite
