hello guys. i badly need some help here. I need a bash script that connects to an ftp server to get and memorize a list of folders in the directory.

ps : i've already written one that connects to the ftp server and can even send some files.

This is an example of my script

Quote:

ftp -inv <<EOF
open xxx.xxx.xx.xx
user USERNAME PASSWORD
lcd /root/xxx
cd /root/xxx/xxxx
binary
put xxx.txt
quit
EOF

If you are looking to syncronize files across machines I would recomend rsync. You can use it in combinaion with ssh for a secure connection.

This will "memorize folders" and only sync files that have changed.

The most common way I have seen to automate/script use of a program that is interactive (e.g. asks for a password, provides a command prompt, etc.) is to use expect. You can make a standalone expect script or you can embed an expect script within a bash script. For instance:

Code:

#!/bin/bash

echo "Bash script about to invoke ftp with expect"

/bin/cat << EOF | /usr/bin/expect
spawn /usr/bin/ftp

expect "ftp> "
send "open\r"

expect "(to) "
send "xxx.xxx.xx.xx\r"

# and so on

interact
EOF

echo "Bash script call to ftp through expect complete. Continuing with additional processing"
