bash - Loop through list of names and copy file explained? -


i've written script copy new user account file new user location. works reading list of usernames , copying file location. can't understand why needed done < $user @ end. can please explain this?

thanks 

user=/home/example/new.txt newuser=$user  loc=/var/account/            cd /home/example  while read newuser cp _newuser.txt $loc/$newuser done < $user

to iterate on each line in file /home/example/new.txt, value of variable user

pls @ http://en.kioskea.net/faq/1757-how-to-read-a-file-line-by-line

< input redirection operator (http://www.tldp.org/ldp/abs/html/io-redirection.html)

you can delete newuser=$user, since not see use of newuser except while loop. due while, newuser assigned new value each iteration.
