您正在使用|(管道)将一个命令的输出定向到另一个命令。你要找的是&&操作符，它只在前一个命令成功的情况下执行下一个命令:

cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apple

Or

cp /templates/apple /templates/used && mv /templates/apple /templates/inuse

(非详尽地)总结bash的命令操作符/分隔符:

| pipes (pipelines) the standard output (stdout) of one command into the standard input of another one. Note that stderr still goes into its default destination, whatever that happen to be. |&pipes both stdout and stderr of one command into the standard input of another one. Very useful, available in bash version 4 and above. && executes the right-hand command of && only if the previous one succeeded. || executes the right-hand command of || only it the previous one failed. ; executes the right-hand command of ; always regardless whether the previous command succeeded or failed. Unless set -e was previously invoked, which causes bash to fail on an error.

使用管道对我来说似乎很奇怪。无论如何，你应该使用逻辑和Bash操作符:

$ cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apples

如果cp命令执行失败，则不会执行rm命令。

或者，您可以使用for循环和cmp创建更详细的命令行。

注意cp A B;rm A正好是mv A b，这也会更快，因为你不需要实际复制字节(假设目标在同一个文件系统上)，只需要重命名文件。所以你需要cp A B;mv A C

另一种选择是在每个命令的末尾输入Ctrl+V Ctrl+J。

示例(用Ctrl+V Ctrl+J替换#)

$ echo 1#
echo 2#
echo 3

输出:

1
2
3

这将执行命令，不管之前的命令是否失败。

同:echo 1;回声2;回声3

如果你想停止执行失败的命令，除了最后一行，在每一行的末尾加上&&。

示例(用Ctrl+V Ctrl+J替换#)

$ echo 1 &&#
failed-command &&#
echo 2

输出:

1
failed-command: command not found

在zsh中，你也可以使用Alt+Enter或Esc+Enter来代替Ctrl+V Ctrl+J

试试这个. .

cp /templates/apple /templates/used && cp /templates/apple /templates/inuse && rm /templates/apple
