我试图动态地将备份位置传递给rman脚本,如下所示.但它失败了语法错误.有没有办法将"/ backup/folder/folder /"传递给rman脚本？如果我只是传递没有"/"的字符串它可以工作,但是"/"它会失败.

rman @${rmanbasepath}rman_replication_from_backups.rcv USING ${dbname} ${backupdir}

backup.rcv

CONNECT AUXILIARY /
run {
allocate auxiliary channel a1 device type disk;
allocate auxiliary channel a2 device type disk;
allocate auxiliary channel a3 device type disk;
allocate auxiliary channel a4 device type disk;
DUPLICATE TARGET DATABASE TO &1
BACKUP LOCATION '&2'

}
EXIT;

配置 spring 安全性时出现以下错误，有人可以帮助我吗？当前配置有资源服务器和认证服务器在同一台服务器上进行测试，这可能会导致冲突。

有没有办法从 kuberentes pod 下载容器镜像？假设我们有多个容器在一个 Pod 中运行，我们想要下载容器，以便我们可以在该容器中离线做一些事情。我们想直接从 Kubernetes pod 下载的原因是因为大多数环境设置已经设置并且容器应该能够以单个 docker 命令启动。

这就像从 kubernetes pod 环境中询问 docker compose 文件。

我们将以下数据从浏览器发送到服务器，除了 JSON 之外，序列化/反序列化数据的最佳方法是什么？

我们最初将数据保存在客户端浏览器中，并在定期检查点将其发送到服务器。由于数据的大小，发送数据时会占用大量浏览器内存和网络。我们希望减少发送到服务器的数据的大小，keys因为每个对象的数据大多相同，但会values发生变化。

我必须在一个脚本中执行以下操作.

/etc/passwd file to display user home directory ownership:

ls -lLd /<usershomedirectory>

我可以按照以下方式访问主路径,请根据使用单行脚本识别的用户主路径帮助我在主路径上运行ls.

grep "" /etc/passwd | cut -f 6 -d :

更新

怎么做更多的ls

# ls -al /<usershomedirectory>/.login
# ls -al /<usershomedirectory>/.cschrc
# ls -al /<usershomedirectory>/.logout
# ls -al /<usershomedirectory>/.profile
# ls -al /<usershomedirectory>/.bash_profile

我基本上在mongo中使用$ all运算符,我得到的输入可能是数组或单个元素,如下所示.那么如何使用下划线将所有元素放在一个数组中然后呢

userId = 'a';
userIds = ['a', 'b', 'c'];
otherId = ['a'] or 'a';
searchArray = [userId, userIds, otherId]
db.collections.find({userIds: {$all: searchArray}})

如果 pod 空闲超过给定的阈值时间，kubernetes 或 Helm 是否支持关闭它？

这在开发环境中非常有用，可以为其他进程提供使用它的空间并节省成本。

何时使用拆分| 作为分隔符,它不会给我预期的输出.有什么解决方案吗？

use warnings;
my $exclude_list = "1213:sutrust.com,sutrust1.com,sutrust3.com|1321:line.com";
my @exclude_client = split(/|/, $exclude_list);
print "Printing excluse  @exclude_client \n";
