assistant: You can create a bash script that uses rsync to efficiently copy files from the source folder to the network share folder. rsync is great for this task because it only copies files that have changed or are new, so you won't need to worry about checking which files are already copied.

First, make sure you have rsync installed on your system. If not, you can install it using your package manager:

For Ubuntu/Debian:

```
sudo apt-get install rsync
```

For CentOS/RHEL:

```
sudo yum install rsync
```

Next, create the bash script. Open a text editor and create a new file called `backup.sh` with the following content:

```bash
#!/bin/bash

SOURCE_FOLDER="/path/to/your/source/folder"
DESTINATION_FOLDER="/path/to/your/network/share/folder"

rsync -avz --progress "$SOURCE_FOLDER" "$DESTINATION_FOLDER"
```

Replace `/path/to/your/source/folder` and `/path/to/your/network/share/folder` with the appropriate paths.

Save the file and make it executable:

```
chmod +x backup.sh
```

To run the script every day at 11 PM, you can add a cron job. Open your crontab with the following command:

```
crontab -e
```

Add the following line at the end of the file, replacing `/path/to/backup.sh` with the actual path to your `backup.sh` script:

```
0 23 * * * /path/to/backup.sh
```

Save and exit. The script will now run every day at 11 PM, copying files from the source folder to the network share folder while skipping files that are already copied.

Note: Make sure your network share is accessible and mounted before running the script. If your network share requires authentication, you may need to modify the script to include the appropriate credentials.

assistant: Sure! Here's a sample bash script that should copy files from a local directory to a network share folder and only copy new files:
```
#!/bin/bash

# Set the source and destination directories
src_dir="/path/to/local/directory"
dest_dir="/path/to/network/share/folder"

# Get the current date and time
current_time=$(date +"%Y-%m-%d_%H-%M-%S")

# Create a log file to keep track of copied files
log_file="/path/to/log/file_$current_time.log"
touch $log_file

# Loop through each file in the source directory
for file in $src_dir/*; do
  # Get the filename and check if it already exists in the destination directory
  filename=$(basename "$file")
  if [ ! -f "$dest_dir/$filename" ]; then
    # Copy the file to the destination directory and add it to the log file
    cp $file $dest_dir
    echo "Copied file: $filename" >> $log_file
  fi
done
```
To schedule this script to run at 11 PM every day, you can use the cron utility. To do so, open your terminal and type:
```
crontab -e
```
This will open the cron file in your default editor. Add the following line to the end of the file:
```
0 23 * * * /path/to/backup/script.sh
```
This will run the backup script at 11 PM every day. Make sure to replace /path/to/backup/script.sh with the actual path to your backup script.

Note that this is just a sample script, and you may need to modify it to suit your specific requirements.

prompter: I also need to add time stamps to every log entry recorded in the log file (separated by a tabulation from the file name) and a separate script that will check for log entries that are more than 1 week old and remove them.
