UNIX for Dummies Questions & Answers

I want to poll a particular file on a Windows shared drive using shell script and copy it to a Unix directory if present.

Step wise execution:
1) Poll/watch for a file in the following location on Windows share:
(SRC_DIR=\\mum\dharmesh\research\ST_DXR_20080821 to DXR.xls)

2) If present, copy(FTP would be a suitable option) it to Unix directory
(DEST_DIR=/home/dharmesh/DXRFiles)
after renaming it.
I have figured out how to FTP and rename it, using the following piece of code:-

ftp -iv <hostname> << EOF
bin
cd "$SRC_DIR"
lcd "$DEST_DIR"
get "ST_DXR_20080821 to DXR.xls" "ST_DXR_20080821.xls"
close
bye
EOF

The real problem lies in Step 1.
Any suggestions/help needed.

Thanks,

If you have Samba, you don't need ftp. If you don't have Samba, how can you monitor the share? Are you trying to find out how to see the Windows share so you can monitor it, or are you trying to figure out how to periodically monitor something which you can already see? Anyway, smbclient or an SMB / CIFS mount is probably the crucial piece of infrastructure you need in order to get going.

Code:

while true; do
  cp /path/to/ugly/samba/share/name/"ugly windows file name here" /path/to/unix/file_name.xls && break
  sleep 300
done
