The usage of tcopy
is
stilts <stilts-flags> tcopy ifmt=<in-format> ofmt=<out-format> [in=]<table> [out=]<out-table>If you don't have the
stilts
script installed,
write "java -jar stilts.jar
" instead of
"stilts
" - see Section 3.
The available <stilts-flags>
are listed
in Section 2.1.
For programmatic invocation,
the Task class for this
command is uk.ac.starlink.ttools.task.TableCopy
.
Parameter values are assigned on the command line as explained in Section 2.3. They are as follows:
ifmt = <in-format>
(String)
in
.
The known formats are listed in Section 5.1.1.
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.
This parameter is ignored for scheme-specified tables.
[Default: (auto)
]
in = <table>
(StarTable)
-
",
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.:<scheme-name>:<scheme-args>
.<
" 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 systems.ofmt = <out-format>
(String)
(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.
