Linux 中从源到目标 nas 路径的文件同步未按预期工作

问：

我们在 linux 机器上没有可用的 rsync 或 xcopy，下面是我们建议的解决方案，有没有更好的方法来实现从源到目标的文件同步

替代建议会有所帮助

#!/bin/bash

# Check for correct number of arguments
if [[ $# -ne 2 ]]; then
    echo "Usage: $0 <source_directory> <user@remote:target_directory>"
    exit 1
fi

# Define the source and target directories from script arguments
SOURCE_DIR="$1"
TARGET_DIR="$2"

# Create a temporary directory for the file lists
TEMP_DIR=$(mktemp -d)

# Create a list of files and directories in the source directory
find "$SOURCE_DIR" -type f > "$TEMP_DIR/source_files.txt"
find "$SOURCE_DIR" -type d > "$TEMP_DIR/source_dirs.txt"

# Create a list of files and directories in the target directory
ssh "${TARGET_DIR%%:*}" "find '${TARGET_DIR##*:}' -type f" > "$TEMP_DIR/target_files.txt"
ssh "${TARGET_DIR%%:*}" "find '${TARGET_DIR##*:}' -type d" > "$TEMP_DIR/target_dirs.txt"

# Sync directories
while IFS= read -r dir
do
    relative_dir="${dir#$SOURCE_DIR}"
    if ! grep -qF "$relative_dir" "$TEMP_DIR/target_dirs.txt"; then
        ssh "${TARGET_DIR%%:*}" "mkdir -p '${TARGET_DIR##*:}$relative_dir'"
    fi
done < "$TEMP_DIR/source_dirs.txt"

# Sync files
while IFS= read -r file
do
    relative_file="${file#$SOURCE_DIR}"
    if ! grep -qF "$relative_file" "$TEMP_DIR/target_files.txt"; then
        scp "$file" "${TARGET_DIR}$relative_file"
    else
        source_info=$(stat -c "%Y %s" "$file")
        target_info=$(ssh "${TARGET_DIR%%:*}" "stat -c '%Y %s' '${TARGET_DIR##*:}$relative_file'")

        if [[ $source_info != $target_info ]]; then
            scp "$file" "${TARGET_DIR}$relative_file"
        fi
    fi
done < "$TEMP_DIR/source_files.txt"

# Clean up
rm -rf "$TEMP_DIR"
