Hello:

I know that $0 will print the command that runs a perl script. Is there a way to capture the commands before the perl script that are piping their results into the perl script?

My goal is to write a bunch of simple programs that love to use pipes, and connect them together. The last program is a perl program, and it would be great if it could record what exactly was done. Here's and example:

> constant_linear_motion 100 2 5 6 3 0 0 0 0 > q1.data; cat q1.data | q_conj >> q1.data; cat q1.data |q_sort |q_graph

If I could get the perl program q_graph to record all the preceding parts starting from "constant_linear_motion", that documentation would be great.

Thanks,
doug
