[CALUG] moving data from program to program

[Walt Smith]

hi Jim,

thanks for the try and link.
The article discusses multiple outputs rather than inputs.
And I may well need to output multiple data to examine intermediate
results. I can easily redirect output to tabs in a gui term.

However, I was looking for a way to do  *multiple data line input*
to a program on a BASH line. Said differently, one line from one source
and another line from another source. I'm wondering where all the BASH 
programmers went ?  In  this case, a program sends one string of data, and
a CSV files ships out another line to "Process_Data".

I mucked around awhile and have a somewhat incomplete solution.
I have a little more work to do.

If there are any BASH people out there, comments appreciated..
The names are changed to reflect actual work performed for 
the convenience of any reader ...  from my real names.

One might groan over the "sleep"... but I'm still wrestling this.

I'm still not clear about the operation of tee in combination
with multiple pipes...   i.e. how many pipes will the data continue
to pump itself thru ..? And how to stop one and let another thru.

And yes, I'm also considering writing data to temporary files
and environment variables. And using options on the command line.
I'd prefer to look at this pipe/tee method first however.

THX !!  ( the following is all one line )
=================
 my_port=`ps | mono Parse_unix_ps.exe`; mono Create_Data.exe | tee  $my_port | grep , | tee >(cat amplitude_offset_128.csv) | mono data_processing.exe ; sleep 2s|tee >(mono Convert_Data.exe)
