Wrench Beginner UNIX question. tail and find commands

hey guys, i'm in a unix course.. and while this is a homework question - i did put alittle effort into it. just wanted to ask before trial and error drives me nuts.

question 13 has us saving the last 30 characters of a file into another file
and question 14 has us saving the list of all the files that are 7 days old starting from your home directory.

i got that the last 30 characters of a file would be found by $tail -30c filename but i can't find an example in the book to save these files. if i add filename2 after filename it'll just show the last 30 characters of each. is it $tail -30c filename > filename2 to save one to the other? and for question 14 i know it would be something with $ find . -atime 7 -exec but i'm not sure how it would save the list to a file. i thought using ">" could only be done with cat in front of it to create files. our book tells us cat is for creating files and mv or cp is for moving or copying. so we're not really creating. so would i use cp or mv? help would be appreciated
