HI, i just wondered if anyone could help, i am trying to write a shell script that will run 5 of my programs in sequential order. i know how to do this, however i don't know how to do it so that the input files can be different and i also want to pipe the out put file so that it can be the input file of the next program. e.g 
at the minute i have it like this;

echo "this is a shell script"

perl ./program1 prog1.input prog1.output
perl ./program2 prog2.input prog2.output

etc

[download]
however,the output of prog1 is the input of prog2 etc. ideally i don't want the file names to matter, i would like for anyone to use my programs. thanks, i realise this isn't strictly a perl question.
