The usage of tpipe
is
stilts <stilts-flags> tpipe ifmt=<in-format> istream=true|false script=<script-file> cmd=<cmds> omode=<out-mode> <mode-args> out=<out-table> ofmt=<out-format> [in=]<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.
Parameter values are assigned on the command line as explained in Section 2.3. They are as follows:
cmd = <cmds>
script
and
cmd
flags should not be mixed in the same invocation.
ifmt = <in-format>
(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.
[Default: (auto)
]in = <table>
ifmt
parameter.
istream = true|false
in
table
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 input 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).
[Default: false
]ofmt = <out-format>
(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.
This parameter must only be given if
omode
has its default value of "out
".
[Default: (auto)
]omode = <out-mode> <mode-args>
out
, which means that
the result will be written as a new table to disk or elsewhere,
as determined by the out
and ofmt
parameters.
However, there are other possibilities, which correspond
to uses to which a table can be put other than outputting it,
such as displaying metadata, calculating statistics,
or populating a table in an SQL database.
For some values of this parameter, additional parameters
(<mode-args>
)
are required to determine the exact behaviour.
Possible values are out
, meta
, stats
, count
, cgi
, discard
, topcat
, plastic
and tosql
.
Use the help=omode
flag
or see Section 5.4 for more information.
[Default: out
]out = <out-table>
omode
has its default value of "out
".
[Default: -
]script = <script-file>
script
and
cmd
flags should not be mixed in the same invocation.
