Hello I am working through projects and I am really confused, I don't understand scripting very well yet, and I do not understand how to use test statements. Here are some questions I am trying to figure out:

Creating an alias called mm that displays only those filesystems that are mounted and contain an ext4 filesystem.

Creating and exporting a varialbe called NEWHOME that is equivalent to the value contained in the HOME variable.

Finding all files that start with the word "host" starting from the /etc directory and save the Standard Output to a file called file1 and the Standard Error to the same file.

Displaying only the lines from the output of the set command that have the word "bash" in them and the list should be sorted alphabetically.

Displaying only the user name in the colon-delimited /etc/passwd file and save the output to a file called users in the current directory.

And here are the ones I am trying to work through that involve the test statements.

Name the test statement that can be used to test to the following scenarios:

The user has read permission to the /etc/hosts file.

The user has read and execute permission to the /etc directory.

The contents of the variable $TEST are equal to the string "success"

The contents of the variable $TEST are equal to the string "success" and the file /etc/hosts exists.

The contents of the variable $TEST are equal to the string "success," or the number 5, or the contents of the variable $RESULT.

Any help with these questions would be greatly appreciated. I am having trouble learning about these commands and I don't know the commands needed to answer these questions. Thank you.
