FTP issues

I am attempting to download a file that will begin with the date in this format: YYYYMMDDsomeending, I can get it to work without the ending but when i add some ending my syntax isnt correct.
Here is the line of the script that DOESNT work.
get $(date +%Y%m%e)'myfile'

It could be your quotes. The following use of date works in bash:

Code:

echo $(date +"%m%d%Y")myfile
10132006myfile

I've also used %d instead of %e to give a number without space padding. According to man date:

Code:

%d     day of month (e.g, 01)
%e     day of month, space padded; same as %_d

Maybe I make a wrong assumption, but it looks like you are inside an FTP client and try to issue the date command. I am not sure if bash expands the $(date) before it feeds the command "get $(date)" to the ftp server.

If it does not expand, create the filename before you open the ftp connection, and then use ncftpget.

If you have multiple files to download, build a list first and then use ncftpget.

ncftpget is a batch mode ftp client.

I figured this out about 20 mins after, but thanks for the quick response

I figured out that the date command was not expanding within the ftp session, but i still cant pass that value(output from date) to the ftp session

Can you put the code block here you are using for the ftp transfer?

Does this help you any further?

#!/bin/bash

file=$(date +%Y%m%e)
echo $file
##wget ftp://testguy:space@10.21.8.58/$file (this works for retrieving the file, I need to be able to change to a directory that will be named 20061017(current date). and i need to pass that value to the ftp session.

ftp -in <<EOF
open 10.21.8.58
user testguy space
cd $file
get $file
rename $file processed
bye
EOF

The only difference I can see is that in my example the variables are quoted, e.g.

Code:

get "$file"

instead of

Code:

get $file

It is mandatory in case your file contains spaces. (Which doesn't happen here)
If that doesn't help I don't know, sorry.

And be careful with

Code:

rename $file processed

After the first time you might try to rename to an existing file. I don't know if ftp can handle that.
