You put $ before a variable when inserting its value in another command, you don't use it in the assignment. It should probably be something like this: PDF=1 Your makeInputAX.sh script doesn't look correct, though. It's possible it's in a library that your program calls, so you wouldn't see the message anywhere in your code. I don't see anything in your scripts that could be producing the 'could not open the somethingelse file for read', it must be coming from the C++ program.

Technically, we can produce PDF and print versions.

The only exception would be environment variables, which are declared using the export command environment variables set in a calling script are copied to the environment of the scripts it calls (but not the other way around). This work is designed as a textbook for a course in software debugging as supplementary material in. So they each have their own variables named PDF, and they operate independently. The variables in makeInputAX.sh are unrelated to the variables in run.sh. Starts a loop whose standard input is redirected to the file list.txt, and each time through the loop it reads a line from the file into the variable PDF. Simply copies that filename to the LIST variable, so $LIST now contains lists.txt as well - it doesn't contain 12345. $1 is the first argument to the script, i.e. To fix that, do I need to look in my cpp files or is there something to these sh files that can help? I made changes to those cpp files and want to see the new outputs I should get, but I am getting an error: could not open the somethingelse file for read However, those files are in a seperate directory, not in /directory/scripts/binaries/what. What also confuses me is that in the command prompt, I then see the outputs from the program, as they were written in the cpp files that are part of the project.

What confuses me is that I thought run.sh runs first, then calls makeInputAX.sh, so how can PDF be assigned to list.txt, when that assignment was in makeInputAX.sh not run.sh? I do see HOLD ON 12345 in the command prompt. So I already know that run.sh reads whats inside list.txt, and assigns 12345 to be the LIST variable. C programming language was developed by a.

My coworker quickly showed me how to run the program but didn't explain how it workedДЄfter making sure all the C++ files compiled properly by running make, he went to the command prompt and typed. I am new to this project and never learned unix before. I am having trouble understanding how my code is working.
