写一个linux同步文件脚本

Sure, I can help you with that! Here's an example script for syncing files between two Linux machines using rsync:

#!/bin/bash

# Source and destination directories
src_dir="/path/to/source/dir"
dest_dir="/path/to/destination/dir"

# Remote machine info
remote_user="username"
remote_ip="192.168.0.100"

# Run rsync to sync files
rsync -avz --delete-before ssh $src_dir $remote_user@$remote_ip:$dest_dir

This script will synchronize all files in the source directory to the destination directory on a remote machine with the specified IP address and username. The `--delete-before` option deletes any files in the destination directory that don't exist in the source directory.

Let me know if you have any further questions!
