+## Terminal coloring and customizing your prompt. 
+
+Your path settings, aliases, and the your prompt can be set with a file.  
+
+On MacOS the file is called `.bash_profile` and is stored at your `~` home directory.  If you use `zsh` instead of bash there is a different file, but it is similar. 
+
+On linux it is `.bashrc` it should be the same in WSL on Windows.

+I have some aliases set, this way when I use Python, I can use the `python` command instead of `python3`.

+## Questions After Today's Class 
 
-## Review today's class
+### How often will we be writing scripts for this class?
 
-```{include} ../_review/2023-10-24.md
-```
+Just a few times to get practice and exposure, but they will come back in 412 and are handy in general. 
 
+### Are bash scripts commonly used today in real world applications or is it something that was used more in the 70s?
 
+They are still super common.  GitHub actions can be written using bash scripting as a strategy.  Lots of systems have build scripts.   
 
-## More Practice
+The thing we would not do that often that we did today was write it from nano instead of a full IDE. 
 
-```{include} ../_practice/2023-10-24.md
-```
+### What is the scope of loop variables?
 
+In bash the loop variable has the same scope as any other variable.  It is the same in Python.  This is one of the many features that can very from language to language. 
 
+### When would I use bash instead of a different programming language?
 
-## Experience Report Evidence
+When you need to do things that are file operations or other os level actions, it can be faster to run if it is in bash.  
+
+### What specific tasks do developers like to use bash to automate?
+
+build processes, file manipulations, git operations.  Anything even just a few steps that would be repetitive and you would have to do often.  
+
+### do people write full programs in bash using things like nano or directly into the terminal?
+
+Yes! Some people especialy people who started programming a long time ago still do.  
+
+More often, using a terminal text editor is a handy tool to use on occasion, but not for every day work. We will work on a remote server, which is an occasion you would use that, on Thursday. 
+
+### Is there a way to save files that you create in the shell?
+
+yes, today we saved the filecheck.sh file. 
+
+### what else can we do with bash?
+
+Its mostly for automating things and processing files or outputs.  
+
+It *can* do anything though. 
+
+### Does running a bash script with `bash <filename>`` remove the need to add #!/bin/bash to the top of it and then make it executable prior to running? 
+
+Yes. by running it like `bash <filename` it works just like passing those lines in the file to bash. 
+
+Alternatively you can put the shebang `#!/bin/bash` at the top to tell the computer what shell to use to run it and then treat it as an executable. 
+
+We will learn about making it executable permissions wise on Thursday. 
+
+
+### Is it possible to create functions in bash scripts?
+
+Yes! [see the GNU bash docs on functions](https://www.gnu.org/software/bash/manual/html_node/Shell-Functions.html)
+
+
+### Where would we see bash the most as a developer? Would we use this language more for an embedded swe role or is it something that's present in every type of programming job.
+
+I think it's present in just about any programming job.  You will always need to work with files at times, you will alwasy have repetitive things that you do not want to do manually.  You may write more or less, but it's alwasy a handy tool to have. 
+
+### Where could I learn more about writing something similar to the workflows we saw?
