来自昨天的scp文件

Question

I want to copy files from a remote Server to a local server. The problem is: I only want to copy the files from yesterday. The remote server is writing logfiles and at 23:59 the logrotation is compressing it to a file [name]_[date].log.gz. At 6:00 in the morning a cronjob on the local server needs to copy the file previously created from the remote server. Does anyone know how to do this?

You can use a script like this

for i in `find /interface/outbound/Web -type f -ctime -1`
do
scp $i user@$destination_server:/destination_directory/
done

in particular the command find as the following features for example:

find . -ctime -1 # which are created less than 1 day ago from currrent folder.
find . -ctime +2 # finds files which are created older than 2 days from currrent folder.

where ctime is the creation time. It's also possible to use the modification time mtime in this way:

find . -mtime 0   # find files modified between now and 1 day ago
find . -mtime -1  # find files modified less than 1 day ago
find . -mtime 1   # find files modified between 24 and 48 hours ago
find . -mtime +1  # find files modified more than 48 hours ago

More information in man find

Edit:

To have the same behaviour from remote to local you can use something like:

latest_file=`ssh user@destination_server find /pathtoDir -type f -ctime -1`
/usr/bin/scp user@destination_server:$latest_file /local_dir 
echo SCP Completed.

At this moment I haven't a Unix environment to make some tests.
