 ### What do the different text colours in terminal mean?
 
-Every terminal environment looks different and the colour scheme varies in different terminal systems. The first part, such as username@machine:~$ shows your username, the name of the computer, the location in the filesystem where you are at the moment. After, the names in blue are folder/directory names. Then, here, we see some .txt files in green. Please note again that this varies in all systems.

After, the names in blue are folder/directory names. Then, here, we see some .txt files in green. Please note again that this varies in all systems. 
 Thus, generally speaking, different file/folder types are indicated by different colours. For example, in our course terminal, blue files indicate it is a folder, green indicates .txt files, and red indicates a zipped file.

 ## Functions in Terminal

+### Are removed files (using `rm`) recoverable? Is there a recycling bin or a staging process for removal of files?
 
 `rm` deletes things permanently, skipping the “Trash” stage altogether, and you will be unable to recover any file that has been deleted with `rm`. It is worth noting that in Unix things are just as you dictate, so be very careful when removing files (look at case, dashes, underscores, etc. and decide which files you want to keep carefully). 
 You can move files using `mv` or `cp` to put the file into another folder to get them out of the way, but which wouldn't delete them the same way the Recycling Bin works to periodically delete things. It’s also worth keeping in mind that moving things to a “recycling bin” doesn’t save space on the computer. So, if you’re trying to remove big files to save space, deleting them permanently is what you actually want.

+### What is the difference between `>` and `>>`?
 `>` will insert the contents indicated by commands preceding it into a file, completely rewriting a file. `>>` will append to a file, retaining any pre-existing text in the file. Also, `>` will create a file if it does not exist, whereas `>>` will not.
 
 ### Can you combine commands such as grep? 
-Yes, you can do this using the pipe | such as grep “something” | grep “something else”
+Yes, you can do this using the pipe `|` such as `grep “something” | grep “something else”`
 
 ### What is the difference between different numerical sort options such as -g and -n?
--g sorts numerically, converting a prefix of each line to a long double-precision floating point number. -n sorts numerically without making any changes to the inputted number, thereby providing a more precise sort.
