[Proj] Only one command line in query of proj.4

[José María]

Hi!

I would like to know if there are a way to write only one command line to
obtain the expected results. I explain:

When you write this :  *$ proj +proj=utm +zone=13 +ellps=WGS84 -f %12.6f*

If you want to recieved the output data:* **500000.000000 4427757.218739*

You must to write in another line with the input data: *-105 40*
*
*
Is it possible to write concatenated command line as this stile?:
*
*
*$ proj +proj=utm +zone=13 +ellps=WGS84 -f %12.6f**  |  **-105 40*
*
*
Thank you
