按首字母筛选顶层目录复制至服务器的脚本问题求助

Got it, let's fix this issue for you. The root problem with your current script is that it isn't restricting its match to only top-level directories—it's recursively picking up any subdirectory that starts with "u" too, which is causing those duplicate copies. Here are two straightforward, reliable approaches to fix this:

Method 1: Use rsync (Recommended) #

rsync is perfect for this kind of selective directory copy because it lets you explicitly include/exclude items with precision. Run this command:

rsync -av --include='u*/' --exclude='*' /your/workstation/source/path/ /your/server/destination/path/

Let's break down what each part does:

• -av: Enables archive mode (preserves permissions, timestamps, etc.) and verbose output so you can see what's being copied.
• --include='u*/': Tells rsync to only include top-level directories that start with "u" (the trailing / ensures we only match directories, not files).
• --exclude='*': Excludes everything else, which prevents any recursive matching of subdirectories.

Method 2: Use find + cp #

If you prefer using basic Unix tools, find can target only top-level directories and pass them to cp:

find /your/workstation/source/path -maxdepth 1 -type d -name 'u*' -exec cp -r {} /your/server/destination/path/ \;

Here's the breakdown:

• -maxdepth 1: Restricts find to only look at the top level of the source directory (no subdirectories).
• -type d: Ensures we only match directories, not files.
• -name 'u*': Filters for directories starting with "u".
• -exec cp -r {} ...: Copies each matching directory recursively to your server destination.

Just make sure to replace /your/workstation/source/path and /your/server/destination/path with your actual directory paths. Both methods will avoid copying those unwanted nested "u" subdirectories and only grab the top-level ones you need.
