I hang here if the ip is wrong
how to set a timeout something like

if (20s not complete "ftp -n -i -v $1") then
echo "error"
fi

Why not check if it's a valid IP address with, say, ping before you attempt to connect?

Thanks for your advice.

The ip address could be pinged but the computer do not have open ftp / firewall any reason that can't connect through ftp and it hang for a very long while.

Any other solution? thanks.

ftp is intended for interactive use, not scripts.

For scripts, use the ncftp suite of utilities.

Thank you for your suggestion.

I replaced the "ftp -n -i -v ip" code to "ncftp -u user -p pass ip"
I want to list out the files of the folder from remote ftp
Before I use "ls . folders" to save the list to a local text file and then manipulate it.

Any other method to list out the files in folders and pass to a parameter?
thanks!

To list the files, use ncftpls. You can redirect the output to a file or use command substitution to save them in a variable.

I changed to use
list=$(ncftpls -u user -p pass -t 2 -x -l ftp://ip/)
echo "$list"

It works great.

Further question is how to split the lines into an array?
