S is a graduate student in the Biology department at MIT and needs to do biological data processing for her research. She needs to run big computational jobs on the lab’s cluster occasionally. She often notes down the required commands and parameters for a program she needs to run in EverNote (A free note taking software for macbook users), so that she can copy paste them later. But she often forgets where she has put her notes and also finds it difficult to search and find the location of the input files on the server if she needs to do the same analysis again. When she can’t locate her notes about the required commands, she looks at the help file in the command line but does not find it very helpful since it has a lot of text and she is only interested in finding how to run the program. She feels that, it would be easier for her to do data analysis if she could just fill the boxes with the parameters and select the command to run. She would also want to see examples, caveats and history of her previous selections.
An example screenshot of the command line help written by another programmer in the lab is shown below (S acknowledges that the information provided is sufficient to figure out how to run the script, but it is not easy to understand): 
Lessons learned
- Uncomfortable in using the commands and parameters to run a program, often forgets them
- Feels comfortable in filling in forms and selecting commands
- Looks up the command line help file to see how to run a program
- Wants to see command format, examples and possible caveats
- Wants to see the history of commands she ran in the past
