 Introduction
 ~~~~~~~~~~~~

    RAR is a powerful tool allowing you to manage and control archive
  files. Console RAR supports archives only in RAR format, the names
  of which usually have a ".rar" extension. ZIP and other formats
  are not supported. Windows users may install GUI RAR version - WinRAR,
  which is able to process many more archive types.

  RAR features include:

    *  Highly sophisticated, original compression algorithm
    *  Special compression algorithms optimized for text, audio,
       graphics data, 32 and 64-bit Intel executables
    *  Better compression than similar tools, using 'solid' archiving
    *  Authenticity verification (registered version only)
    *  Self-extracting archives and volumes (SFX)
    *  Ability to recover physically damaged archives
    *  Locking, password, file order list, file security & more ...


 Configuration file
 ~~~~~~~~~~~~~~~~~~

  RAR for Unix reads configuration information from the file .rarrc
  in the user's home directory (stored in HOME environment variable)
  or in /etc directory.

  RAR for Windows reads configuration information from the file rar.ini,
  placed in the same directory as the rar.exe file.

  This file may contain the following string:

  switches=any RAR switches, separated by spaces

  For example:

  switches=-m5 -s


 Environment variable
 ~~~~~~~~~~~~~~~~~~~~

    Default parameters may be added to the RAR command line by establishing
    an environment variable "RAR".

    For instance, in UNIX following lines may be added to your profile:

      RAR='-s -md1024'
      export RAR

    RAR will use this string as default parameters in the command line and
    will create "solid" archives with 1024 KB sliding dictionary size.

    RAR handles options with priority as following:

       command line switches                   highest priority
       switches in the RAR variable            lower priority
       switches saved in configuration file    lowest priority


 Log file
 ~~~~~~~~

  If the switch -ilog is specified in the command line or configuration
  file, RAR will write informational messages, concerning errors
  encountered while processing archives, into a log file. In Unix
  this file is named .rarlog and placed in the user's home directory.
  In Windows it is named rar.log and placed in the same directory as
  the rar.exe file. Switch -ilog allows to override the default log name.


 The file order list for solid archiving - rarfiles.lst
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  rarfiles.lst contains a user-defined file list, which tells RAR
  the order in which to add files to a solid archive. It may contain
  file names, wildcards and special entry - $default. The default
  entry defines the place in order list for files not matched
  with other entries in this file. The comment character is ';'.

  In Windows this file should be placed in the same directory as RAR,
  in Unix - to the user's home directory or in /etc.

  Tips to provide improved compression and speed of operation:

  - similar files should be grouped together in the archive;
  - frequently accessed files should be placed at the beginning.

  Normally masks placed nearer to the top of list have a higher priority,
  but there is an exception from this rule. If rarfiles.lst contains such
  two masks that all files matched by one mask are also matched by another,
  that mask which matches a smaller subset of file names will have higher
  priority regardless of its position in the list. For example, if you have
  *.cpp and f*.cpp masks, f*.cpp has a higher priority, so the position of
  'filename.cpp' will be chosen according to 'f*.cpp', not '*.cpp'.


 RAR command line syntax
 ~~~~~~~~~~~~~~~~~~~~~~~

 Syntax

    RAR <command>  [ -<switches> ]  <archive>  [ <@listfiles...> ]
        [ <files...> ]  [ <path_to_extract\> ]

 Description

    Command line options (commands and switches) provide control of
    creating and managing archives with RAR. The command is a string (or a
    single letter) which commands RAR to perform a corresponding action.
    Switches are designed to modify the way RAR performs the action. Other
    parameters are archive name and files to be archived into or extracted
    from the archive.

    Listfiles are plain text files that contain names of files to process.
    File names should start at the first column. It is possible to
    put comments to the listfile after // characters. For example,
    you may create backup.lst containing the following strings:

    c:\work\doc\*.txt         //backup text documents
    c:\work\image\*.bmp       //backup pictures
    c:\work\misc

    and then run:

       rar a backup @backup.lst

    If you wish to read file names from stdin (standard input),
    specify the empty listfile name (just @).

    Win32 console RAR uses OEM (DOS) encoding in list files.

    You may specify both usual file names and list files in the same
    command line. If neither files nor listfiles are specified,
    then *.* is implied and RAR will process all files

    In a UNIX environment you need to quote wildcards to avoid them
    being expanded by shell. For example, this command will extract
    *.asm files from RAR archives in current path:

       rar e '*.rar' '*.asm'


    Command could be any of the following:

    a       Add files to archive.

            Example:

            create or update existent archive myarch, adding all files
            in the current directory

            rar a myarch


    c       Add archive comment. Comments are displayed while the archive is
            being processed. Comment length is limited to 62000 bytes

            Examples:

            rar c distrib.rar

            Also comments may be added from a file using -z[file] switch.
            The following command adds a comment from info.txt file:

            rar c -zinfo.txt dummy


    cf      Add files comment. File comments are displayed when the 'v'
            command is given. File comment length is limited to 32767 bytes.

            Example:

            rar cf bigarch *.txt


    ch      Change archive parameters.

            This command can be used with most of archive modification
            switches to modify archive parameters. It is especially
            convenient for switches like -av, -cl, -cu, -tl, which do not
            have a dedicated command.

            It is not able to recompress, encrypt or decrypt archive data
            and it cannot merge or create volumes. If used without any
            switches, 'ch' command just copies the archive data without
            modification.

            Example:

            Set archive time to latest file:

            rar ch -tl files.rar


    cw      Write archive comment to specified file.

            If used with -fcu switch, the format of output file
            is low endian Unicode. Otherwise it is ASCII.

            Examples:

            1) rar cw arc comment.txt

            2) rar cw -fcu arc unicode.txt


    d       Delete files from archive. Please note if the processing of this
            command results in removing all the files from the archive,
            the empty archive would removed.


    e       Extract files to current directory.


    f       Freshen files in archive. Updates those files changed since they
            were packed to the archive. This command will not add new files
            to the archive.


    i[i|c|h|t]=<string>
            Find string in archives.

            Supports following optional parameters:

              i - case insensitive search (default);

              c - case sensitive search;

              h - hexadecimal search;

              t - use ANSI, Unicode and OEM character tables (Win32 only);

            If no parameters are specified, it is possible to use
            the simplified command syntax i<string> instead of i=<string>

            It is allowed to specify 't' modifier with other parameters,
            for example, ict=string performs case sensitive search
            using all mentioned above character tables.

            Examples:

            1) rar "ic=first level" -r c:\*.rar *.txt

            Perform case sensitive search of "first level" string
            in *.txt files in *.rar archives on the disk c:

            2) rar ih=f0e0aeaeab2d83e3a9 -r e:\texts

            Search for hex string f0 e0 ae ae ab 2d 83 e3 a9
            in rar archives in e:\texts directory.


    k       Lock archive. Any command which intends to change the archive
            will be ignored.

            Example:

            rar k final.rar


    l[t,b]  List contents of archive [technical]. Files are listed as with
            the 'v' command with the exception of the file path. i.e. only
            the file name is displayed. Optional technical information
            (host OS, solid flag and old version flag) is displayed
            when 't' modifier is used. Modifier 'b' forces RAR to output
            only bare file names without any additional information.


    m[f]    Move to archive [files only]. Moving files and directories
            results in the files and directories being erased upon
            successful completion of the packing operation. Directories will
            not be removed if 'f' modifier is used and/or '-ed' switch is
            applied.


    p       Print file to stdout.

            You may use this command together with -inul switch to disable
            all RAR messages and print only file data. It may be important
            when you need to send a file to stdout for use in pipes.


    r       Repair archive. Archive repairing is performed in two stages.
            First, the damaged archive is searched for a recovery record
            (see 'rr' command). If the archive contains a recovery record
            and if the portion of the damaged data is continuous and less
            than N*512 bytes, where N is number of recovery sectors placed
            into the archive, the chance of successful archive
            reconstruction is very high. When this stage has been completed,
            a new archive will be created, called fixed.arcname.rar,
            where 'arcname' is the original (damaged) archive name.

            If a broken archive does not contain a recovery record or if
            the archive is not completely recovered due to major damage, a
            second stage is performed. During this stage only the archive
            structure is reconstructed and it is impossible to recover
            files which fail the CRC validation, it is still possible,
            however, to recover undamaged files, which were inaccessible
            due to the broken archive structure. Mostly this is useful
            for non-solid archives.

            When the second stage is completed, the reconstructed archive
            will be saved as rebuilt.arcname.rar, where 'arcname' is
            the original archive name.

            RAR/DOS32 version uses _recover.rar and _reconst.rar instead
            of names mentioned aboves.

            While the recovery is in progress, RAR may prompt the user for
            assistance when a suspicious file is detected.

                      Suspicious entry

              Name:  <possibly filename>
              Size:  <size>    Packed: <compressed size>

                      Add it: Yes/No/All

            Answer 'y' to add this entry to the file fixed.arcname.rar.

            Example:

            rar r buggy.rar


    rc      Reconstruct missing and damaged volumes using recovery volumes
            (.rev files). You need to specify any existing volume
