DERB(1)                         ICU 57.1 Manual                        DERB(1)

NAME
       derb - disassemble a resource bundle

SYNOPSIS
       derb  [  -h,  -?,  --help  ]  [ -V, --version ] [ -v, --verbose ] [ -e,
       --encoding encoding ] [ --bom ] [ -t, --truncate  [  size  ]  ]  [  -s,
       --sourcedir  source  ] [ -d, --destdir destination ] [ -i, --icudatadir
       directory ] [ -c, --to-stdout ] bundle ...

DESCRIPTION
       derb reads the compiled resource bundle files  passed  on  the  command
       line and write them back in text form.  The resulting text files have a
       .txt extension while compiled resource bundle  source  files  typically
       have a .res extension.

       It is customary to name the resource bundles by their locale name, i.e.
       to use a local identifier for the bundle filename, e.g.  ja_JP.res  for
       Japanese  (Japan) data, or root.res for the root bundle.  This is espe-
       cially important for derb since  the  locale  name  is  not  accessible
       directly from the compiled resource bundle, and to know which locale to
       ask for when opening the bundle.  derb will produce a file  whose  base
       name  is  the  base  name of the compiled resource file itself.  If the
       --to-stdout, -c option is used, however, the text will  be  written  on
       the standard output.

OPTIONS
       -h, -?, --help
              Print help about usage and exit.

       -V, --version
              Print the version of derb and exit.

       -v, --verbose
              Display extra informative messages during execution.

       -A, --suppressAliases
              Don't follow aliases when producing output.

       -e, --encoding encoding
              Set  the  encoding  used to write output files to encoding.  The
              default encoding is the invariant (subset of  ASCII  or  EBCDIC)
              codepage for the system (see section INVARIANT CHARACTERS).  The
              choice of the encoding does not affect the data, just their rep-
              resentation. Characters that cannot be represented in the encod-
              ing will be represented using \uhhhh escape sequences.

       --bom  Write a byte order mark (BOM) at the beginning of the file.

       -l, --locale locale
              Set the locale for the resource bundle, which is  used  both  in
              the generated text and as the base name of the output file.

       -t, --truncate [ size ]
              Truncate  individual  resources (strings or binary data) to size
              bytes. The default if size is not specified is 80 bytes.

       -s, --sourcedir source
              Set the source directory to source.  The default  source  direc-
              tory  is the current directory.  If - is passed for source, then
              the bundle will be looked for in its default location, specified
              by the ICU_DATA environment variable (or defaulting to the loca-
              tion set when ICU was built if ICU_DATA is not set).

       -d, --destdir destination
              Set the destination directory to destination.  The default  des-
              tination  directory  is  specified  by  the environment variable
              ICU_DATA or is the location set when ICU was built  if  ICU_DATA
              is not set.

       -i, --icudatadir directory
              Look  for  any necessary ICU data files in directory.  For exam-
              ple, when processing collation overrides, the  file  ucadata.dat
              must be located.  The default ICU data directory is specified by
              the environment variable ICU_DATA.

       -c, --to-stdout
              Write the disassembled bundle on standard output instead of into
              a file.

CAVEATS
       When  the  option --bom is used, the character U+FEFF is written in the
       destination encoding regardless of whether it is a Unicode  transforma-
       tion  format (UTF) or not.  This option should only be used with an UTF
       encoding, as byte order marks are not meaningful for other encodings.

INVARIANT CHARACTERS
       The invariant character set consists of the following  set  of  charac-
       ters,  expressed  as  a  standard  POSIX  regular expression: [a-z]|[A-
       Z]|[0-9]|_| |+|-|*|/.  This is the set which is guaranteed to be avail-
       able regardless of code page.

ENVIRONMENT
       ICU_DATA  Specifies  the  directory  containing  ICU  data. Defaults to
                 ${prefix}/share/icu/57.1/.  Some tools in ICU depend  on  the
                 presence  of the trailing slash. It is thus important to make
                 sure that it is present if ICU_DATA is set.
