B.33.2 Examples

Here are some examples of tcopy in use:

stilts tcopy stars.fits stars.xml

Copies a FITS table to a VOTable. Since no input format is specified, the format is automatically detected (FITS is one of the formats for which this is possible). Since no output format is specified, the stars.xml filename is examined to make a guess at the kind of output to write: the .xml ending is taken to mean a TABLEDATA-encoded VOTable.

stilts tcopy stars.fits stars.xml ifmt=fits ofmt=votable

Does the same as the previous example, but the input and output formats have been specified explicitly.

stilts tcopy ofmt=text http://remote.host/data/vizer.xml.gz#4 -

Prints the contents of a remote, compressed VOTable to the terminal in a human-readable form. The #4 at the end of the URL indicates that the data from the fifth TABLE element in the remote document are to be used. The gzip compression of the table is taken care of automatically.

stilts tcopy ifmt=csv ofmt=latex spec.csv

Converts a comma-separated values file to a LaTeX table environment, writing the result to standard output.

stilts -classpath /usr/local/jars/pg73jdbc3.jar \
       -Djdbc.drivers=org.postgresql.Driver \
       tcopy in="jdbc:postgresql://localhost/imsim#SELECT ra, dec, Imag FROM dqc" \
             ofmt=fits wfslist.cat

Makes an SQL query on a PostgreSQL database and writes the results to a FITS file. The whole command is shown here, to show that the classpath is augmented to include the PostgreSQL driver class, and the driver class is named using the jdbc.drivers system property. As you can see, using SQL from Java is a bit fiddly, and there are other ways to perform this setup than on the command line - see Section 3.4 and tpipe's omode=tosql output mode.
