  unpack

  NAME

    unpack - expand files compressed with pack

  SYNOPSIS

    unpack [-cdfhlLnNrtvV19] [-S suffix] [file ...]

  DESCRIPTION

    The unpack(1) utility uncompresses files compressed with pack(1). It
    replaces the compressed files with their unpacked form. The specified file
    might or might not have the .z extension.

    The file cannot be unpacked for one of the following reasons:
    *     It cannot be opened.
    *     It does not appear to have been compressed by pack(1).
    *     A file with the unpacked name already exists.
    *     The file name without the .z extension is more than {NAME_MAX} bytes
          long. This is possible if the packed file was brought from another
          system.

    The options for unpack(1) are:

    -c
        Write on standard output; keep original files unchanged

    -d
        Decompress

    -f

    -h

    -l

    -L

    -n

    -N

    -q

    -r

    -S .suf
        Use suffix .suf on compressed files

    -t
        Test compressed file integrity

    -v
        Verbose mode

    -V
