DERB(1)                                    ICU 74.2 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 iden‐
       tifier for the bundle filename, e.g.  ja_JP.res for Japanese (Japan) data,  or  root.res  for
       the root bundle.  This is especially important for derb since the locale name is not accessi‐
       ble  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  com‐
       piled 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 repre‐
              sentation. Characters that cannot be represented in the encoding 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 directory is the current di‐
              rectory.  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 destination 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 example, when processing col‐
              lation  overrides,  the file ucadata.dat must be located.  The default ICU data direc‐
              tory 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 transformation format (UTF) or not.  This option should
       only  be  used  with an UTF encoding, as byte order marks are not meaningful for other encod‐
       ings.

INVARIANT CHARACTERS
       The invariant character set consists of the following set of characters, expressed as a stan‐
       dard POSIX regular expression: [a-z]|[A-Z]|[0-9]|_| |+|-|*|/.  This is the set which is guar‐
       anteed to be available regardless of code page.

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/74.2/.
                 Some tools in ICU depend on the presence of the trailing slash. It is  thus  impor‐
                 tant to make sure that it is present if ICU_DATA is set.
