NAME

       rar - archive files with compression

SYNOPSIS
       rar <command> [-<switch 1> -<switch N>] archive [files...]



DESCRIPTION

       This manual page documents briefly the rar archiver.

       This  manual  page  was  written  for the Debian GNU/Linux distribution

       because the original program does not have a manual page.

       Commands and options described here are as of rar 3.0b5.



       rar and unrar are programs for manipulation with .rar archives.



OPTIONS

       After the program name comes a command and then optional switches  with

       dashes before them.

       A  summary  of commands is included below.  For a complete description,

       run rar without options.



       a      Add files to archive.



       c      Add archive comment. Comment length is limited to 62000 bytes.



       cf     Add files comment. File comments are displayed when the 'v' com‐

              mand is given. File comment length is limited to 32767 bytes.



       cw     Write archive comment to a specified file.



       d      Delete files from archive.



       e      Extract  files  to current directory. Does not create any subdi‐

              rectories.



       f      Freshen files in archive. Updates those files changed since they

              were packed to the archive. This command will not add new to the
              archive.

       k      Lock archive. Any command which intend  to  change  the  archive

              will be ignored.

       l[t]   List content of archive [technical]. Files are listed as the 'v'

              command with the exception of the file path. i.e.  the file name

              is  displayed. Optional technical information displayed when 't'

              modifier is used.



       m[f]   Move to archive [files only]. Directories will not be removed if

              'f' modifier is used and/or '-ed' switch is applied.



       p      Print file to stdout.



       r      Repair archive. For further details look in rar.txt.



       rc     Reconstruct missing volumes using recovery volumes (.rev files).

              You need to specify any existing volume as the archive name, for

              example, 'rar rc backup.part03.rar'.



       rr[N]  Add  data  recovery  record.  Optionally,  redundant information

              (recovery record) may be added to an archive.



       rv[N]  Create recovery volumes (.rev files), which can be later used to

              reconstruct  missing  files  in  a volume set.  This command has

              sense only for multivolume archives.  For further  details  look

              in rar.txt.



       s[name|-]

              Convert  archive to or from SFX. The archive is merged with SFX-

              module in the user's home directory.



       t      Test archive files.



       u      Update files in archive. Adds files not already in  the  archive

              and updates files changed since they were packed to the archive.



       v[t]   Verbosely list archive [technical]



       x      Extract files with full path.



SWITCHES

       NOTE:  Every  switch  must be separated by a whitespace. They cannot be

       put together.



       -?     Display help on commands and switches. The same as when none  or

              an illegal command line option is entered.



       --     This  switch  tells to RAR that there is no more switches in the

              command line. It could be useful, if either archive or file name

              starts  from  '-' character. Without '--' switch such name would

              be treated as switch.



       -ac    Clear Archive attribute after compression or extraction (Windows

              version only).



       -ag[format]

              Generate  archive name using the current date and time.  Appends

              the current date string to an archive name when creating an  ar‐

              chive.  Useful  for  daily backups.  For further details look in

              rar.txt.



       -ao    Add files with Archive attribute set (Windows version only).



       -ap    Set path inside archive. This path is merged to file names  when

              adding  files  to  an  archive  and removed from file names when

              extracting.



       -as    Synchronize archive contents. If this switch is  used  when  ar‐

              chiving,  those archived files which are not present in the list

              of the currently added files, will be deleted from  archive.  It

              is convenient to use this switch in combination with -u (update)

              to synchronize contents of an archive and  an  archiving  direc‐

              tory.



       -av    Put   authenticity   verification  (registered  versions  only).

              Details in register.txt.



       -av-   Disable AV checking or adding.



       -cfg-  Disable read configuration and environment.



       -cl    Convert file names to lower case.



       -cu    Convert file names to upper case.



       -c-    Disable comments show.



       -df    Delete files after archiving. This switch  in  combination  with

              the command "A" performs the same action as the command "M".



       -dh    Open  shared  files.  Allows  to  process  files opened by other

              applications for writing.



       -ds    Do not sort files while adding to a solid archive.



       -ed    Do not add empty directories.



       -ee    Do not process extended attributes. Only for OS/2 versions.



       -en    Do not add "end of archive" block.



              This switch cannot be used with volumes, because the end of  ar‐

              chive  block  contains  information important for correct volume

              processing.



       -ep    Exclude paths from names.



       -ep1   Exclude base dir from names.



       -ep2   Expand paths to full. Store full file paths (except a drive let‐

              ter and leading path separator) when archiving.

              Specifies file exclude attributes mask.



       -f     Freshen files. May be used with archive extraction or creation.



       -hp<password>

              Encrypt both file data and headers.  The password is case-sensi‐

              tive. If you omit the password on the command line, you will  be

              prompted with message "Enter password".



       -idp   Disable percentage indicator.



       -ieml[.][addr]

              Send archive by email. Win32 version only.



       -ierr  Send all messages to stderr.



       -ilog  Log errors to file (registered versions only).



       -inul  Disable all messages.



       -isnd  Enable sound.



       -k     Lock  archive.  Any  command which intends to change the archive

              will be ignored.



       -kb    Keep broken extracted files.



       -m<0..5>

              Set compression level (0-store...3-default...5-best). By default

              rar uses -m3 method (Normal compression).



       -mc<par>

              Set  advanced  compression parameters.  For further details look

              in rar.txt.



       -md<size>

              Set dictionary  size  in  Kb  (64,128,256,512,1024,2048,4097  or

              a,b,c,d,e,f,g)



       -ms[list]

              Specify file types to store.



       -o+    Overwrite existing files.



       -o-    Do not overwrite existing files.



       -ol    Save symbolic links as the link instead of the file.



       -os    Save NTFS streams. Win32 version only.



       -ow    Save file owner and group.

              chiving.  The password is case-sensitive. If you omit the  pass‐

              word  on  the  command  line,  you will be prompted with message

              "Enter password".



       -p-    Do not query password.



       -r     Recurse subdirectories.



       -r0    Similar to -r, but when used with the commands  'a',  'u',  'f',

              'm' will recurse subdirectories only for wildcard names.



       -ri<p>[:<s>]

              Set priority and sleep time. Available only in RAR for Windows.



       -rr[N] Add data recovery record.



       -rv[N] Create recovery volumes.  -s Create solid archive.



       -s<N>  Create  solid  groups using file count. Similar to -s, but reset

              solid statistics after compressing <N> files.



       -se    Create solid groups using extension. Similar to  -s,  but  reset

              solid statistics if file extension is changed.



       -sv    Create independent solid volumes. Similar to -s, but reset solid

              statistics as soon as possible when starting a new volume.



       -sv-   Create dependent solid volumes. Similar  to  -s,  but  reset  of

              solid statistics is disabled.



       -s-    Disable solid archiving.



       -sfx[name]

              Create  SFX  archives.  The archive is merged with SFX-module in

              the user's home directory.



       -t     Test files after archiving. This switch is especially useful  in

              combination with the move command, so files will be deleted only

              if archive had been successfully tested.



       -tk    Keep original archive time. Prevents rar from modifying the  ar‐

              chive date when changing an archive.



       -tl    Set archive time to latest file. Forces rar to set the date of a

              tories  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.



       -w<path>

              Assign work directory.



       -x<file>

              Exclude  specified file. Wildcards may be used and you may spec‐

              ify the switch '-x' several times.
