linux - ntfs 上的 Cygwin rsync 不会硬链接(hard link) (--link-dest) 文件

Question

在我的 Windows 10 comp 上，我有 ntfs 分区。 Cygwin 是以下版本:

$ cygcheck --version
cygcheck (cygwin) 2.5.1
System Checker for Cygwin
Copyright (C) 1998 - 2016 Red Hat, Inc.

我已经创建了一个脚本文件:

#!/bin/bash

echo 'clean up current dir'

rm -R source
rm -R 1/
rm -R 2/

echo 'create source file'

mkdir source
echo "Today is a lovely day" > source/source_file.txt

echo "rsync source to the 1 folder"

rsync -aPhv source/ 1/

echo "rsync source to the 2 folder but link destination 1/"

rsync -rlt --modify-window=10 --stats -P --link-dest=1 source/ 2/

echo "disk usage"

du -b --max-depth=1

echo "ls"

ls -l 2/source_file.txt

当我运行该文件时，我得到以下输出:

$ ./link_dest_doesnt_work.bash.sh

为什么文件 2/source_file.txt 不是硬链接(hard link)？

Answer 1

您的问题是 --link-dest 中的路径，根据 man 页面，这是相对于 DEST 目录的路径。

在上面的跟踪中可以看到相应的错误:--link-dest arg does not exist: 1

将参数更改为 --link-dest=..\1 应该会修复。
