drPACS is a simple yet flexible and effective pipeliner for Unix commands. There is a document (currently Appendix A in the PACS cookbook) describing this is more detail,but here is just a teaser to get a feel for what you can do with it.
Assuming it has been installed, a $DRPACS environment variable points to where the code lives, and normally $DRPACS/bin will have been added to your search path.
Simple examples how to start
Step 1: generate the control Pipefile (hint: it's a Makefile)
pipeline $DRPACS/cat/pipeline.001 > Pipefile
pipeline 4 step1 step2 step3 step4 > Pipefile
Step 2: set some parameters
pipepar -c pipepar -c project=c0184.3B_108PG2130.13 carmaRefant=2 pipepar interval=5 carmaRefant=3
Step 3: run the pipe
pipe all pipe step2 pipe all pipe clean
more advanced examples
Running pipeline in a set of directories
method 1: old-style c-shell method
foreach dir (`cat dirs.txt`) cd $dir pipepar foo=3.3 pipe step3 all cd .. end
method 2: using piperun
piperun dirs.txt 'pipepar foo=3.3 ; pipe step3 all'
Scatterplot from a set of directories
piperun dirs.txt pipepar -v foo -v bar > foo_bar.tab tabplot foo_bar.tab
piperun -n 4 dirs.txt pipe step2 all
PACS, in parallel
piperun -n 4 -c -o pipe.log dirs.txt 'pipepar -c project=%s showPlots=False; pipe clean all'
