linux下面使用的rar 解压缩的东西

            Win32 version stores owner, group, file permissions and
            audit information, but only if you have necessary privileges
            to read them. Note that only NTFS file system supports
            file based security under Windows.

    -o+     Overwrite existing files.


    -o-     Do not overwrite existing files.


    -p<p>   Encrypt files with the string <p> as password while archiving.
            The password is case-sensitive. If you omit the password on the
            command line, you will be prompted with message "Enter password".

            Example:

            rar a -pmyhoney secret1 *.txt

            add files *.txt and encrypt them with password "myhoney".


    -p-     Do not query password


    -r      Recurse subdirectories. May be used with commands:
            a, u, f, m, x, e, t, p, v, l, c, cf and s.

            When used with the commands 'a', 'u', 'f', 'm' will process
            files in all sub-directories as well as the current working
            directory.

            When used with the commands x, e, t, p, v, l, c, cf or s will
            process all archives in sub-directories as well as the current
            working directory.


    -r0     Similar to -r, but when used with the commands 'a', 'u', 'f',
            'm' will recurse subdirectories only for those names, which
            include wildcard characters '*' and '?'


    -ri<p>[:<s>]
            Set priority and sleep time. Available only in RAR for Windows.
            This switch is used to regulate system load by RAR in a
            multitasking environment. The possible task priority values are
            from 0 to 15. When <p> is equal to 0, the default task priority
            is used, 1 corresponding to the lowest task priority, 15 - to
            the highest. The sleep time <s> is a value from 0 to 1000
            (milliseconds). This is the period of time that RAR will give
            back to system after every read or write during the packing or
            unpacking operation. The sleep time setting is useful when
            several tasks with the same priority are running in the system.

            Example:

            execute RAR with default priority and 10 ms of sleep after
            each read or write

            rar a -r -sfx -ri0:10 backup *.*


    -rr[N]  Add a data recovery record. This switch is used when creating or
            modifying archive to add a data recovery record to the archive.
            See the 'rr[N]' command description for details.


    -s      Create solid archive. Solid is a special archive type. Please
            refer to the appendix "Glossary" for further information.

            Example:

            create solid archive sources.rar with 512 KB dictionary,
            recursing all directories, starting with the current directory.
            Add only .asm files:

            rar a -s -md512 sources.rar *.asm -r


    -s<N>   Create solid groups using file count

            Similar to -s, but reset solid statistics after compressing
            <N> files. Usually decreases compression, but also
            decreases losses in case of solid archive damages.


    -se     Create solid groups using extension

            Similar to -s, but reset solid statistics if file extension
            is changed. Usually decreases compression, but also
            decreases losses from solid archive damages.


    -sv     Create independent solid volumes

            By default RAR tries to reset solid statistics as soon
            as possible when starting a new volume, but only 
            if a lot enough data was packed after a previous reset
            (at least a few megabytes).

            This switch forces RAR to ignore packed data size and attempt
            to reset statistics for volumes of any size. It decreases
            compression, but increases chances to extract a part of data 
            if one of solid volumes in volume set was lost or damaged.

            Note that sometimes RAR cannot reset statistics even
            using this switch. For example, it cannot be done when 
            compressing one large file split between several volumes.
            RAR is able to reset solid statistics only between separate 
            files, but not inside of single file.

            Ignored, if used to create non-volume archive.


    -sv-    Create dependent solid volumes

            Disables to reset solid statistics between volumes.

            It slightly increases compression, but significantly reduces 
            chances to extract a part of data if one of solid volumes 
            in volume set was lost or damaged.

            Ignored, if used to create non-volume archive.


    -s-     Disable solid archiving


    -sfx[name]
            Create SFX archives. If this switch is used when creating a new
            archive, a Self-Extracting archive (using a module in file
            default.sfx or specified in the switch) would be created.
            In the Windows version default.sfx should be placed in the
            same directory as the rar.exe, in Unix and BeOS - in the user's
            home directory, in /usr/lib or /usr/local/lib.

            Example:

            rar a -sfxwincon.sfx myinst

            create SelF-eXtracting (SFX) archive using wincon.sfx
            SFX-module.


    -tk     Keep original archive date. Prevents RAR from modifying the
            archive date when changing an archive.


    -tl     Set archive time to newest file. Forces RAR to set the date of a
            changed archive to the date of the newest file in the archive.


    -tn<time>
            Process files newer than the specified time period. Format
            of the time string is:

            [<ndays>d][<nhours>h][<nminutes>m][<nseconds>s]

            For example, use switch -tn15d to process files newer
            than 15 days and -tn2h30m to process files newer than
            2 hours 30 minutes.


    -to<time>
            Process files older than the specified time period. Format
            of the switch is the same as -tn<time>.


    -u      Update files. May be used with archive extraction or creation.
            The command string "a -u" is equivalent to the command 'u', you
            could also use the switch '-u' with the commands 'm' or 'mf'. If
            the switch '-u' is used with the commands 'x' or 'e', then files
            not present on the disk and files newer than their copies on the
            disk would extracted from the archive.


    -v<size>[k|b|f|m|M]
            Create volumes with size=<size>*1000 [*1024 | *1].
            By default this switch uses <size> as thousands (1000) of bytes
            (not 1024 x bytes). You may also enter the size in kilobytes
            using the symbol 'k', in bytes using the symbol 'b',
            in megabytes - 'm', in millions of bytes - 'M' or select
            one of several predefined values using the symbol 'f'
            following the numerical value. Predefined values can be
            360, 720, 1200, 1440 or 2880 and replaced with corresponding
            floppy disk size.

            If the size is omitted, autodetection will be used.

            If volumes are created on removable media, then after
            the first volume has been created, user will be prompted
            with:

              Create next volume: Yes/No/All

            At this moment in time, you should change the disks. Answering
            'A' will cause all volumes to be created without a pause.

            The first volume file in a multi-volume set has the extension
            .RAR, following volumes are numbered from .R00 to .R99.

            When extracting or testing a multi-volume archive you must use
            only the first volume name (*.RAR). If there is no next volume
            on the drive and the disk is removable, the user will be
            prompted with:

             Insert disk with <next volume name>

            Insert the disk with the correct volume and press any key.

            If while extracting, the next volume is not found and volumes
            are placed on the non-removable disk, RAR will abort with
            the error message:

             Cannot find <volume name>

            Archive volumes may not be modified. The commands 'd', 'f', 'u',
            's' can not be used with Multi-volume sets. The command 'a' may
            be used only for the creation of a new multi-volume sequence.

            It is possible, although unlikely, that the file size, of a file
            in a multi-volume set, could be greater than it's uncompressed
            size. This is due to the fact that 'storing' (no compression if
            size increases) cannot be enabled for multi-volume sets.

            Archive volumes may be Self-Extracting (SFX). Such an archive
            should be created using both the '-v' and '-sfx' switches.

            Example:

            create archive in volumes of fixed size:

            rar a -s -v1440 floparch.rar *.*

            will create solid volumes of size 1440000 bytes.

    -vd     Erase disk contents before creating volume

            All files and directories on the target disk will be erased
            when '-vd' is used.  The switch applies only to removable
            media, the hard disk cannot be erased using this switch.

    -vp     Pause before each volume

            By default RAR asks for confirmation before creating or 
            unpacking next volume only for removable drives.
            This switch forces RAR to ask such confirmation always.
            It can be useful if disk space is limited and you wish
            to copy each volume to another media immediately after
            creating.

    -w<p>   Assign work directory as <p>. This switch may be used to assign
            the directory for temporary files.


    -x<f>   Exclude specified file <f>, wildcards may be used. You may
            specify the switch '-x' several times:

            Example:

            rar a -r -x*.bak -x*.rar rawfiles

            *.bak and *.rar files will not be added to rawfiles


    -x@<lf> Exclude files using specified list file.

            Example:

            rar a [e-mail] arch *.exe


    -y      Assume Yes on all queries.


    -z<f>   Read archive comment from file <f>.


 Limitations
 ~~~~~~~~~~~

    Pathname is limited to 259 symbols.

    Maximum archive comment length is 62000 bytes.

    Command limitations:

    The commands 'd','u','f','c','cf' will not operate with archive
    volumes.

    The command 'a' cannot be used to update an archive volume, only to
    create one.


 Exit values
 ~~~~~~~~~~~

    RAR exits with a zero code (0) in case of successful operation. The exit
    code of non-zero means the operation is cancelled due to error:

     255   USER BREAK       User stopped the process

       8   MEMORY ERROR     Not enough memory for operation

       7   USER ERROR       Command line option error

       6   OPEN ERROR       Open file error

       5   WRITE ERROR      Write to disk error

       4   LOCKED ARCHIVE   Attempt to modify an archive previously locked
                            by the 'k' command

       3   CRC ERROR        A CRC error occurred when unpacking

       2   FATAL ERROR      A fatal error occurred

       1   WARNING          Non fatal error(s) occurred

       0   SUCCESS          Successful operation (User exit)


 Glossary
 ~~~~~~~~

    Archive      Special file containing one or more files optionally
                 compressed and/or encrypted.

    Compression  A method of encoding data to reduce it's size.

    CRC          Cyclic Redundancy Check. Mathematical method calculating
                 special checking information for data validity.

    SFX          Archive module used to extract files from when executed.
                 (SelF-eXtracting module), usually in the form of a .EXE
                 file.

    Solid        An archive packed using a special compression method which
                 sees all files as one continuous data stream. Particularly
                 advantageous when packing a large number of small files.

    Volume       Part of a split archive. Splitting an archive to volumes
                 allows storing them on diskettes. Solid volumes must be
                 extracted starting from first in sequence.
