[NMLUG] Move files via FTP

[timothyemerick at yahoo.com (Tim Emerick)]

Thanks for the reply Ed.
   
  Having googled more I did find an article from Linux Journal regarding automating ftp transfers and the use of .netrc to automate logins.  I stole/munged/hacked this script together.  See any obvious flaws?
   
  I have this set up to run every hour via cron.  I currently have stdout going to a log file for each transfer so I can check for success or not on each transfer.  It would be nice if I could have the entire session appended to previous sessions so I can have a daily log of all activity to reflect back on.  I would also need to have this log rotated daily but haven't figured out how to do the logrotate thing yet.

notify=temerick@vtaig.com
  cd $scandir
for warrantyfile in `find . -cmin +5 -type f -printf %P'\040'`
 do
 ftp -i -v > $logfile 2>&1 <<mayday
  open jlscan.com
  cd /new
  put $warrantyfile
  quit
mayday
 if egrep "421 S|426 C|450 R|500 S|501 S|503 B|550 R|553 R" $logfile > /dev/nul 2>&1
  then
   cat $logfile | mail -s "Error transmitting a warranty file to JL-Scan" $notify
  else
   rm -fr $warrantyfile
 fi
done

  You might want to use -cmin to get changed time, not access time. This 
might need some tweeking, because I haven't actually set up a test 
environment or actually tried find like that.

#!/bin/bash

( echo "cd $ftp_dir" ; echo "put $file" ; echo "quit" ) | ftp $ftp_host
mv $file ../backup

Subject: [NMLUG] Move files via FTP


I have a small project that I need some help with. My bash scripting skills 
are terrible and I haven't been able to find a utility to do what I want 
which is this in a nutshell.

Here's some pseudo-code:

1. Look at a particular directory on local computer.
2. List all files that are older than 15 minutes (file might still be in the 
process of creation)
3. Copy those files to an FTP server that requires a username/password 
combo.
4. If the file already exists on the FTP server then throw somebody an email 
letting them know.
5. If the transfer is successful then delete the original (or move it to 
another directory).

I would like to run this every hour via cron.

Anything out there already existing?

Thanks!

Tim

PS. Doing a little googling while I was composing helped me figure out a 
couple of things.

1. I can get a listing of files older than 15 minutes by using the 
following. find . -amin +15

2. I can use .netrc to automagically login to the remote ftp server with my 
credentials.

3. How do I do 2 things with my list of found files??? (ftp put and then 
delete/move)?

4. How do I get an email of just file tranfer errors? (file already exists, 
etc)


Talk is cheap. Use Yahoo! Messenger to make PC-to-Phone calls. Great rates 
starting at 1?/min.
