       stilts-tmulti - Writes multiple tables to a single container file


       stilts tmulti [in=<table> [<table> ...]] [ifmt=<in-format>] [multi=true|false]
                     [istream=true|false] [icmd=<cmds>] [out=<out-file>] [ofmt=<out-format>]


       tmulti takes multiple input tables and writes them as separate tables to a  single  output
       container  file. The container file must be of some format which can contain more than one
       table, for instance a FITS file (which can  contain  multiple  extensions)  or  a  VOTable
       document  (which  can  contain multiple TABLE elements). Filtering may be performed on the
       tables prior to writing them. It is not necessary that all the tables  are  similar  (e.g.
       that  they all have the same type and number of columns), but the same processing commands
       will be applied to all of them. For more individual control, use the tmultin task.


       in=<table> [<table> ...]
              Locations of the input tables. Either specify  the  parameter  multiple  times,  or
              supply the input tables as a space-separated list within a single use.

              The following table location forms are allowed:

                * A filename.

                * A URL.

                * The  special  value  "-", meaning standard input. In this case the input format
                  must be given explicitly using the ifmt parameter. Note that  not  all  formats
                  can be streamed in this way.

                * A  system  command  line  with  either  a  "<" character at the start, or a "|"
                  character at the end ("<syscmd" or "syscmd|"). This executes the given pipeline
                  and  reads  from its standard output. This will probably only work on unix-like
               Compression in any of the supported compression formats (Unix  compress,  gzip  or
              bzip2) is expanded automatically.

              A  list  of  input  table  locations  may be given in an external file by using the
              indirction character '@'. Thus "in=@filename" causes the file filename to  be  read
              for  a list of input table locations. The locations in the file should each be on a
              separate line.

              Specifies the format of the input table as specified by  parameter  in.  The  known
              formats  are  listed in SUN/256. This flag can be used if you know what format your
              table is in. If it has the special value (auto) (the default), then an attempt will
              be made to detect the format of the table automatically. This cannot always be done
              correctly however, in which case the program will exit  with  an  error  explaining
              which formats were attempted.

              The same format parameter applies to all the tables specified by in.

              Determines  whether  all tables, or just the first one, from input table files will
              be used. If set false, then just the first table from each file named by in will be
              used. If true, then all tables present in those input files will be used. This only
              has an effect for file formats which are capable of containing more than one table,
              which effectively means FITS and VOTable and their variants.

              If  set  true,  the  input  table  specified  by the in parameter will be read as a
              stream. It is necessary to give the ifmt parameter in this case. Depending  on  the
              required operations and processing mode, this may cause the read to fail (sometimes
              it is necessary to read the table more than once). It is not normally necessary  to
              set this flag; in most cases the data will be streamed automatically if that is the
              best thing to do. However it can sometimes  result  in  less  resource  usage  when
              processing large files in certain formats (such as VOTable).

              The same streaming flag applies to all the tables specified by in.

              Specifies  processing to be performed on each input table as specified by parameter
              in, before any other processing has taken place. The value of this parameter is one
              or  more  of  the  filter commands described in SUN/256. If more than one is given,
              they must be separated  by  semicolon  characters  (";").  This  parameter  can  be
              repeated  multiple  times on the same command line to build up a list of processing
              steps. The sequence of commands given in this way defines the  processing  pipeline
              which is performed on the table.

              Commands may alteratively be supplied in an external file, by using the indirection
              character '@'. Thus a value of "@filename" causes the file filename to be read  for
              a  list of filter commands to execute. The commands in the file may be separated by
              newline characters and/or semicolons, and lines which are blank or which start with
              a '#' character are ignored.

              The  location  of the output file. This is usually a filename to write to. If it is
              equal to the special value "-" the output will be written to standard output.

              Specifies the format in which the output tables will be written (one of the ones in
              SUN/256 - matching is case-insensitive and you can use just the first few letters).
              If it has the special value "(auto)" (the default), then the output  filename  will
              be examined to try to guess what sort of file is required usually by looking at the
              extension. If it's not obvious from the filename what output format is intended, an
              error will result.

              Not  all  output  formats are capable of writing multiple tables; if you choose one
              that is not, an error will result.

       HTML format:


       STILTS version 3.1-5-debian

       This  is  the  Debian  version  of Stilts, which lack the support of some file formats and
       network protocols. For differences see
