Shell Programming and Scripting

Hello, I found the forum’s information very helpful and informative. I am relatively new to UNIX programming. I am researching how to write a UNIX shell script to ftp all files from specific host folder to a client server. Also need to archive all transferred files, send a message (email) if any file was not transferred successfully and save (email) a log after the script's execution.
Where can find additional information or script’s examples?
Thank you in advance

man ftp
man sendmail
man bash

First, consider reading Classic Shell Scripting book for learning shell scripting...

How can save the ftp transferred details in log ?

Hi everyone
I have a shell script to ftp (2 .gz files) and send some emails with attachments.
Expert opinions welcome! ... Any comments or suggestions would be most welcome.

Here is the script:
#!/bin/bash

MESSAGE4="GZIP: Fail"
vFName="arc-$(date '+%y%m%d')"
mFile="/name1/name2/name3/"
