Running from a script

Often it is more convenient to run catpair from a prepared script rather than answering the prompts interactively. This end is simply achieved using Unix's input redirection mechanism. Simply enter the responses to the various prompts into a text file, in the correct order, using a text editor. Then type:

catpair < script_file

where script_file is the name of the file you have created. Figure  shows an annotated example catpair script for pairing with Cartesian coordinates. This script is available as file:

/star/share/cursa/catpair_cart.script

An example script showing pairing with spherical-polar coordinates is available as file:

/star/share/cursa/catpair_sphplr.script

It may be convenient to use these scripts as starting points for developing your own scripts.
