如何使用“cp”命令静默复制大量文件？

Question

默认情况下，cp显示要复制的所有文件的列表。我使用的命令是：

sudo cp -r $WORKSPACE/DMS/dist/conf/* $WORKSPACE/DMS/NewWar/NewFiles/conf

这将显示正在复制的文件的完整列表，如下所示：

+ sudo cp -r /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/XmlSchema-1.3.1.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/XmlSchema-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/activation-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/annogen-0.1.0.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/annogen-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/antlr.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/avalon-framework-4.1.3.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-api-1.2.4.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-api-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-dom-1.2.4.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-dom-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-impl-1.2.4.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axiom-impl-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axis.jar /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/axis2-LICENSE.txt /var/lib/jenkins/workspace/6.5.10/DMS/OldBase/dist/sharedlib/backport-util-concurrent-2.2.jar 

..。名单还在继续。在这种情况下，如何静默地复制文件？

Answer 1

如果您必须在脚本的其余部分使用set -x，但不希望在cp命令中看到它，只需在cp之前关闭它，然后再继续运行。

剧本：

#!/bin/bash
set -x
...
set +x
sudo cp -r "$WORKSPACE/DMS/dist/conf/"* "$WORKSPACE/DMS/NewWar/NewFiles/conf"
set -x
...

注意，您不应该在脚本中使用sudo，并且应该引用所有变量。
