Creating and deleting certain files
How would you create and then delete a file called "$SHELL"?

How would you create and then delete a file that begins with the symbol #?

How would you create and then delete a file that begins with the symbol -?

I think I should use cat for creating and rm for removing but I'm not sure of the exact syntax for this.

'touch' for creating
'rm' for removing

'man touch' - for details on 'touch'
'man rm' - for details on 'rm'

'man ksh' - for details of 'ksh' shell [if that's what you're using]

2.

rm - '-aaa'
or rm anything_not_existent '-aaa'
