I have thought about this for quite some time and know what I want to do but am having some trouble at it. I have a text file filled with numbers like this, there are more in the file obviously. Each number is separated by a space.
The idea is to use these numbers to calculate some kind of a profit. The first line is price per item and the second line indicates an action. 1 means you bought it, -1 means you sold it, 0 means no action. So, to demonstrate things, you buy an item at $1, the running total is -1, you sell (add 3), subtract 2, ignore the no transaction, then add 5, leaving you with 5. Anyway, I have a script called test and if you run it, it allows you to enter a line of numbers separate by spaces, when you hit enter it displays the second line results. I think the idea is to feed lines in from testcase.txt to the check.sh file (the one I'm scripting now) and compare the program output with the expected output in testcase.txt. So, if I can get every odd line from testcase and feed it in, read the result output, then I can compare it. Is there a good way to do this? To call a .sh file within a .sh file?
Oh yeah, if I can somehow feed a line from testcase to test.sh and store its result in a variable (ala the second line), then there might be a way to get it done.
