NAME    [Toc]    [Back]

       asort  -  Sorts or merges files and supports multiple collating
 weight sequences

SYNOPSIS    [Toc]    [Back]

       asort   [-m]   [-o output_file]    [-Abdfinruv]    [-Ccollate_sequence]
  [-k  keydef]...  [-t character] [-T directory]
 [-y] [kilobytes] [-z record_size]... file...

       asort -c  [-u] [-Abdfinruv] [-Ccollate_sequence] [-k  keydef]...
 [-t character] [-T directory] [-y] [kilobytes] [-z
       record_size]...  file...

       The following syntax is maintained for  backward  compatibility
  but  may  be  withdrawn in a future release: asort
       [-Abcdfimnruv] [-Ccollate_sequence] [-o  output_file]  [-t
       character]    [-T    directory]   [-y]   [kilobytes]   [-z
       record_size]   [+fskip]   [.cskip]    [-fskip]    [.cskip]
       [-bdfinr]... file...

OPTIONS    [Toc]    [Back]

       The  asort  command  includes the same options as the sort
       command  (see  sort(1))  in  addition  to  the   following
       options:  Specifies  the  collating  weight sequence to be
       used in sorting the data files.  When this option is specified,
  the asort command does not use the collating table
       from the locale database.  Instead, the command uses a set
       of  special  system and user collating tables to determine
       the  collating  weights  of  characters,  including  userdefined
 characters (UDCs).

              The  collate_sequence  argument can be in long form
              (for example, "Pinyin  Radical  Stroke")  or  short
              form  (for example, prs). The codeset of the locale
              determines which  collation  weight  names  can  be
              specified  for collate_sequence. The following list
              specifies the long and short collation weight names
              that are valid for supported codesets.

              For DEC Hanzi:

              Pinyon  (or p) Radical (or r) Stroke (or s) For DEC
              Hanyu, Taiwanese EUC, and BIG-5:

              Phonetic (or p) Radical (or r) Stroke (or s) Uses a
              breadth-first  sorting  mechanism  instead  of  the
              default depth-first mechanism  to  sort  the  input
              data.   To  have  any effect, the -v option must be
              used together with the -C option.

DESCRIPTION    [Toc]    [Back]

       The asort command sorts  lines  in  its  input  files  and
       writes  the  result to standard output.  The asort command
       is similar to the sort command. See the sort(1)  reference
       page  for information about features the two commands have
       in common.

       The asort command provides additional  features  for  processing
  multiple  collating  weight  sequences  used with
       Asian languages, such as  Chinese.   For  example,  pinyon
       (p),  stroke  (s),  and  radical  (r) are three dimensions
       along which characters can be ordered in  Simplified  Chinese.
   The -C option allows users to specify the priority
       level that these dimensions have during sorting. For example,
  -C  srp  specifies  that characters should be sorted
       first by stroke, then by  radical,  then  by  pinyon.  The
       specified  sequence  is applied to user-defined characters
       (UDCs) as well as to standard characters.

       When the -C option is specified, the default  behavior  of
       the  asort  command is to use a depth-first sorting mechanism
 to sort the input files.  With the depth-first mechanism,
  pairs  of  multibyte characters in a sort field are
       compared by exhausting all the specified collating weights
       and/or  internal  codes  one at a time until the collating
       order is resolved.  Only when two characters are identical
       is  the next pair of characters compared.  The depth-first
       sorting mechanism is also called character sorting.

       However, the asort command provides the -v option  to  use
       the  Asian VMS-like breadth-first sorting mechanism.  With
       the breadth-first mechanism, pairs of multibyte characters
       in  a  sort  field  are compared using the first collating
       weight for all the characters in  the  sort  field  first.
       Only when two sets of data in a sort field are computed to
       have the same collating  order  are  succeeding  collating
       weights  used  for  resolving  the  collating  order.  The
       breadth-first sorting mechanism is sometimes called string

NOTES    [Toc]    [Back]

       Currently,  the  asort  command  is supported for use only
       with Chinese codesets.

EXIT STATUS    [Toc]    [Back]

       The asort command returns the following exit  values:  All
       input  files were output successfully, or -c was specified
       and the input file was correctly sorted.  If -c was specified,
  the file was not ordered as specified, or if the -c
       and -u options were both specified, two input  lines  were
       found with equal keys.  An error occurred.

EXAMPLES    [Toc]    [Back]

       Unless stated otherwise, the following examples assume the
       locale setting is  zh_TW.dechanyu:  To  perform  character
       sorting  first by stroke and then by radical, enter: asort
       -C"Stroke Radical" names

              This command displays the lines in names sorted  in
              ascending  order according to the number of strokes
              in characters.  If the number of strokes happen  to
              be the same for two characters, the radicals of the
              characters  determine  how   the   characters   are
              ordered.An  alternative short form of the same command
 is as follows: asort  -Csr  names  To  perform
              string  sorting first by stroke and then by radical
              in a way similar to the sort command  available  on
              an Asian VMS system, enter: asort -v -C"Stroke Radical"
