UNIX for Dummies Questions & Answers

I was wondering what command lines i could use to do the following.

1. mail a file to a user with a subject line "HELLO". Also, send a Blind carbon copy to a different user?

2. Display the number of files AND directories in a given directory?

3. Display the last 5 files in a given directory?

I've searched all the manual pages i could possibly think of and i can't seem to find the answers to these. Thanks!

Have you missed these pages?

Code:

1. man mail

2. man ls, man wc

3. man tail

Regards

1.) mailx -s Hello to.person1@mail.com to.person2@mail.com < /path/file

Regards

wouldn't that just mail the file to both users?

I need to mail the file to one user, and in the same line send a blind carbon copy to a different user.

Ans(Q1) :
mail -s HELLO person1@domain.com -b person2@domain.com <file.txt
(This will send the contents of the file as mail contents to person1 and blind carbon copies to person2)

uuencode file.txt file.txt | mail -s HELLO person1@domain.com -b person2@domain.com
(this will send the file as attachement to person1 and blind carbon copy to person2.Attachment can be send if and only if the file is encoded)


Ans(Q2) :
ls -Rl | awk 'BEGIN{d=0;f=0;l=0;}{if(/^d/){d++}else if(/^-/){f++}else if(/^l/){l++}}END{print "Directories: "d "\nFiles: " f "\nLinks: " l}'

Ans(Q3) :
ls | tail -5
(List the last five files in a directory)
