Shell Programming and Scripting

Dear all,

I would like to write a script to push periodically some downloaded files from one host to another box.

Basically, I have host A downloading files.
When those files are downloaded they are moved automatically to a directory called: /home/user_A/downloaded, still on host A.

Then I need to move all the files in the downloaded directory from host A to host B, furthermore I want to clear up the downloaded directory on host A, as otherwise there won't be enough space there for future downloads.

So I want to write a shell script that:
1) periodically push all the files from the downloaded directory on host A to host B
2) Afterwards deletes all the files in the downloaded directory of host A

What is the best way to do that?

I would like to call this "push.sh" script, every hour in a cron job on host A:

Code:

push.sh
#!/bin/bash
cd /home/user_A/downloaded
scp * user_B@192.168.1.10:/home/user/store -user_B_passwd
rm -f *

My problem is: How to be sure that all the files are going to be completely transferred to host B before they are deleted on host A???
What should I do to be sure that the scp command is finished before executing the rm -f * command??

Many thanks for your help and keep up the good work!

Check the return code:

Code:

cd /home/user_A/downloaded
scp * user_B@192.168.1.10:/home/user/store -user_B_passwd
if [[ $? = 0 ]] then
  echo "File(s) have been moved..."
else
  echo "Error moving files..."
  exit 1
fi
rm -f *

In addition you could do a compare on the from/to directories before doing the 'rm':

Code:

# Before 'scp'
ls -1 /home/user_A/downloaded/* > from_dir.txt
# After 'scp'
ssh user_B@192.168.1.10 'ls -1 /home/user/store/*' > to_dir.txt

then do a 'diff' on the two files
