I have a .ksh file with the following code

#!/bin/ksh

USR='test'
HT='test.mycompany.com'
DIRNAME='/mydir/'

function LsFiles {
sftp $USR@$HT <<end_ftp
cd $DIRNAME
ls "-lrt *.pdf"
bye
end_ftp
}

LsFiles | grep "$@" | awk '{print $NF}' > list_of_files.txt

Questions
1. When I run the script it connects to the server but gives me following error message
Can't ls: "'/mydir/-lrt *.pdf" not found

How can I specify enter after cd $DIRNAME in an automated script?

2. What does grep "$@" do?

Thanks in advance

seems it would be easier to obtain a list of files using ssh then use scp to do the actual copying.

ssh (for system administration and running remote commands)
sftp (for an ftp like interactive prompt (read: babysitting))
scp (for automated file transfers).

i would also install sshfs for extra ease-of-use of drag-and-drop local file copy emulation.

also, are you sure the directory exists ? each command should be flushed automatically in linux (you shouldnt have to simulate hitting the enter key).

$@ prints out all the command line arguments

Thanks for your quick reply. Could you please provide the sample syntax using scp in this case. I only need to copy based on ls "-lrt *.pdf"

Hi and welcome to LinuxQuestions!
Remove the double quotes: they prevent filename expansion so that the asterisk is matched literally.
Not necessary. In standard input the newline acts as "enter".
$@ is a special parameter that means all the arguments passed to the script on the command line. Look at the difference between $* and $@ here for more details.
You're welcome!
