-rw-r--r-- 1 27773 27773 12 Mar 23 21:41 aws-2

目标文件夹尚不存在。我尝试将 2 个 aws 文件 rsync 到目标文件夹中。这是我的命令：

rsync \
--include="aws*" \
--exclude="*" \
-avh --chmod=a=rw "source/." "destination"

我试图做的是 rsync 2 个 aws 文件并在目标文件夹中更改它们的权限。运行命令后，我收到一个错误，文件不在目标文件夹中。仅创建了文件夹。以下是错误：

它说权限被拒绝，没有复制文件。我还不明白哪个权限导致了问题。我的源文件和目录似乎没问题。创建的目标文件夹似乎也没问题。

PS：我精确地说明我的 rsync 命令发生在 bash 脚本中

答案1

目录需要执行权限以便进程可以访问（打开）它们。

当您使用时--chmod=a=rw，目标目录会被创建，但随后其权限会立即设置为drw-rw-rw，以致其内容变得不可访问（“ failed to stat”），例如给定

$ tree
.
└── source
    ├── file1
    ├── file2
    └── file3

1 directory, 3 files

然后

$ rsync --include="file*" --exclude="*" -avh --chmod=a=rw source/ destination/
sending incremental file list
created directory destination
rsync: failed to modify permissions on "/home/steeldriver/destination/.": Permission denied (13)
rsync: recv_generator: failed to stat "/home/steeldriver/destination/file1": Permission denied (13)
rsync: recv_generator: failed to stat "/home/steeldriver/destination/file2": Permission denied (13)
rsync: recv_generator: failed to stat "/home/steeldriver/destination/file3": Permission denied (13)
./

sent 107 bytes  received 502 bytes  1.22K bytes/sec
total size is 0  speedup is 0.00
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1183) [sender=3.1.1]

失败，因为

$ ls -dl destination/
drw-rw-rw- 2 steeldriver steeldriver 4096 Mar 23 18:24 destination/

以便

$ ls -al destination/
ls: cannot access 'destination/.': Permission denied
ls: cannot access 'destination/..': Permission denied
total 0
d????????? ? ? ? ?            ? .
d????????? ? ? ? ?            ? ..

解决方案是使用--chmod=a=rwX（或者，等效地，--chmod=ugo=rwX）

$ rsync --include="file*" --exclude="*" -avh --chmod=ugo=rwX source/ destination/
sending incremental file list
created directory destination
./
file1
file2
file3

sent 224 bytes  received 110 bytes  668.00 bytes/sec
total size is 0  speedup is 0.00

其中X符号模式意味着

execute/search only if the file is  a  directory  or
already  has  execute permission for some use

看man chmod
