NAME

       comprez - safely (un)tar and (de)feather files and directories

SYNOPSIS

       comprez  [  -t | -T ] [ -v | -V ] [ -l | -L ] [ -gz | -z | -I | -lz | -Z | -zip | -jar ] [
       -# ] [ -s suffix ] [ -m mode ] [ -p | -P ] [ -h ] [ -- ] file ...

DESCRIPTION

       Comprez is a simple, safe and convenient front-end  for  the  compress(1),  uncompress(1),
       gzip(1),  bzip2(1),  lzip(1),  tar(1),  zip(1)  and unzip(1) utilities for compressing and
       uncompressing files and directories.  It processes each of its arguments according to  the
       type of the file or directory given:

       If the argument is a plain file, then the file is compressed, ie, feathered.

       If the argument is a compressed file with a name ending in .Z, .gz, .z, .bz2, .lz, .zip or
       .jar, then the file is uncompressed, ie, defeathered.

       If the argument is a directory, then the directory is archived into one tar  or  zip  file
       which is then compressed, ie, tarred and feathered.

       If   the   argument   is   a  compressed  tar  or  zip  archive  with  a  name  ending  in
       .{tar.,tar,ta,t}{Z,gz,z,bz2,lz} or  .{zip,jar},  then  the  archive  is  uncompressed  and
       untarred, ie, untarred and defeathered.

       The  new compressed or uncompressed version will be in the same directory as the original.
       A compressed file is always uncompressed into a file with the same name sans  the  feather
       suffix.   A  compressed tar or zip archive is always unpacked into a subdirectory with the
       same name as the archive sans the tar and feather suffix, even  if  the  archive  did  not
       itself contain such a subdirectory.

OPTIONS

       --        Interprets all following arguments as files instead of options.

       -#        Where  #  is  a  digit  from  1 through 9.  This option is passed on to gzip(1),
                 bzip2(1), lzip(1) and zip(1) when feathering with  them.   --fast  may  be  used
                 instead of -1 and --best instead of -9.

       -gz       Uses gzip(1) and a .gz compression suffix when feathering.

       -h        Prints a helpful usage message.

       -I        Uses bzip2(1) and a .bz2 compression suffix when feathering.

       -l        Lists the file or directory name created resulting from each argument.

       -L        Does not report created files or directories.  Default.

       -lz       Uses lzip(1) and a .lz compression suffix when feathering.

       -m mode   Apply  the  given  chmod(1)  mode argument to any created tar and feather files.
                 Before this argument is  applied,  the  files  have  the  same  read  and  write
                 permissions  as the directories from which they were created.  For security, the
                 default argument is go-rwx.  If the mode is -, then no argument is applied.  See
                 chmod(1) for all other allowable formats of this argument.

       -p        Preserves modes when untarring by giving the p flag to tar(1).  Default.

       -P        Doesn't  preserve modes when untarring by not giving the p flag to tar(1).  This
                 option may be necessary on systems where  ordinary  users  are  allowed  to  run
                 chown(2).

       -s suffix Creates  tar and feather files using the given suffix style.  The default suffix
                 style is .tar.Z.  Note that the suffix style does not dictate the  program  used
                 for feathering nor the compression suffix.

       -t        Only lists the table of contents of the given files.  Does not make any changes.

       -T        (Un)tars and (de)feathers the given files according to their type.  Default.

       -v        Verbose output.  For example, reports compression ratios when feathering.

       -V        Non-verbose  output.   Does  not  report  compression ratios.  Default.  -q is a
                 synonym.

       -z        Uses gzip(1) and a .z compression suffix when feathering.

       -Z        Uses compress(1) and a .Z compression suffix when feathering.  Default.

       -zip, -jar
                 Uses  zip(1)  and  a  .zip  or  .jar  compression  suffix  when  tarring  and/or
                 feathering.   The zip format combines tarring and feathering.  WARNING: zip does
                 not preserve complete Unix filesystem information for  the  files  it  archives,
                 such  as  links, some permissions, etc.  A tar(1)-based format should be used if
                 this is required.

ENVIRONMENT VARIABLES

       ZOPTS     This variable may be set to a string of  the  above  options  to  supersede  the
                 default  settings.  They may still be overridden by options given on the command
                 line.

       GZIP      This environment variable for gzip(1) is not passed on by comprez so that gzip's
                 behavior is standard and predictable.

       ZIPOPT, UNZIP
                 These environment variables for zip(1) and unzip(1) are not passed on by comprez
                 so that their behavior is standard and predictable.

BUGS

       There should be an option to allow the use of another directory for temporary files needed
       during  the (un)tarring and (de)feathering processes.  This would make comprez more useful
       when the quota or disk is nearly full.

       There should be -k and -K options for keeping the original input files or not.

CAVEATS

       Comprez is written to work with gzip versions 1.2.3 and 1.2.4, bzip2  versions  0.9.0  and
       1.0.0,  Unix  zip version 2.0.1 and Unix unzip version 5.12.  Other versions will probably
       work safely, too, but should still be checked for compatibility.

       Every effort has been made to assure that the use of this program will  not  lead  to  the
       inappropriate  deletion  or  corruption  of  any  files.   However,  there  are  never any
       guarantees, so please use at your own risk.
