简短的回答

复制myfile.txt到/foo/bar/myfile.txt，使用:

mkdir -p /foo/bar && cp myfile.txt $_

这是如何工作的呢?

这里有几个组件，所以我将一步一步地介绍所有语法。

POSIX标准中指定的mkdir实用程序创建目录。根据文档，-p参数将导致mkdir

创建任何缺少的中间路径名组件

这意味着当调用mkdir -p /foo/bar时，如果/foo不存在，mkdir将创建/foo和/foo/bar。(如果没有-p，它将抛出一个错误。

&&列表操作符，如POSIX标准(或Bash手册，如果你喜欢)中所述，其效果是只有在mkdir -p /foo/bar成功执行时才执行cp myfile.txt $_。这意味着如果mkdir失败，cp命令将不会尝试执行，原因有很多。

最后，我们传递给cp的第二个参数$_是一个“特殊参数”，可以方便地避免重复长参数(如文件路径)，而不必将它们存储在变量中。根据Bash手册，它:

展开到上一个命令的最后一个参数

在本例中，这是我们传递给mkdir的/foo/bar。因此cp命令展开为cp myfile.txt /foo/bar，将myfile.txt复制到新创建的/foo/bar目录中。

注意$_不是POSIX标准的一部分，所以理论上Unix变体可能有一个不支持这个构造的shell。然而，我不知道任何现代shell不支持$_;当然Bash, Dash和zsh都喜欢。

最后注意:我在回答开头给出的命令假设目录名中没有空格。如果你正在处理带有空格的名称，你需要引用它们，这样不同的单词就不会被视为mkdir或cp的不同参数。所以你的命令实际上是这样的:

mkdir -p "/my directory/name with/spaces" && cp "my filename with spaces.txt" "$_"

只需在你的.bashrc中添加以下代码，如果需要可以调整。适用于Ubuntu。

mkcp() {
    test -d "$2" || mkdir -p "$2"
    cp -r "$1" "$2"
}

如 如果您想将“test”文件复制到目标目录“d” 使用,

mkcp test a/b/c/d

MKCP将首先检查目标目录是否存在，如果不存在则创建并复制源文件/目录。

我强烈建议你也这么做。 只是工作。

同样，my/location/poo .txt this/doesn /exist/yet/poo .txt

虽然已经很晚了，但对新手还是有帮助的。如果你需要自动创建文件夹，rsync应该是你最好的朋友。

rsync /path/to/sourcefile /path/to/tragetdir/thatdoestexist/

I wrote a support script for cp, called CP (note capital letters) that's intended to do exactly this. Script will check for errors in the path you've put in (except the last one which is the destination) and if all is well, it will do an mkdir -p step to create the destination path before starting the copy. At this point the regular cp utility takes over and any switches you use with CP (like -r, -p, -rpL gets piped directly to cp). Before you use my script, there are a few things you need to understand.

all the info here can be accessed by doing CP --help. CP --help-all include's cp's switches. regular cp won't do the copy if it doesn't find the destination path. You don't have such a safety net for typos with CP. You're destination will be created, so if you misspell your destination as /usrr/share/icons or /usr/share/icon well that's what's going to be created. regular cp tends to model it's behavior on the existing path: cp /a/b /c/d will vary on whether d exists or not. if d is an existing folder, cp will copy b into it, making /c/d/b. If d doesn't exist, b will be copied into c and renamed to d. If d exists but is a file and b is a file, it will be overwritten by b's copy. If c doesn't exist, cp doesn't do the copy and exits.

CP不能奢侈地从现有路径中获取线索，所以它必须有一些非常坚定的行为模式。CP假设要复制的项被放到目标路径中，而不是目标本身(也就是源文件/文件夹的重命名副本)。意义:

如果d是一个文件夹，“CP /a/b /c/d”会得到/c/d/b 如果/c/b中的b是一个文件夹，“CP /a/b /c/b”将生成/c/b/b。 如果b和d都是文件:CP /a/b /c/d将生成/c/d(其中d是b的副本)。同样情况下CP /a/b /c/b也是如此。

这种默认CP行为可以通过“——rename”开关改变。在这种情况下，我们假设

"CP——rename /a/b /c/d"是将b复制到/c，并将副本重命名为d。

最后几点注意事项:与cp一样，cp可以一次复制多个项，最后列出的路径被假定为目的地。只要使用引号，它还可以处理带有空格的路径。

CP将检查您输入的路径，并确保它们在复制之前存在。在严格模式下(可通过——strict开关获得)，要复制的所有文件/文件夹必须存在，否则不会进行复制。在松弛模式(——松弛)下，如果列出的项中至少有一个存在，则复制将继续。放松模式是默认模式，您可以通过开关临时更改模式，也可以通过在脚本开头设置变量easy_going永久更改模式。

下面是如何安装它:

在非根终端中，执行以下操作:

sudo echo > /usr/bin/CP; sudo chmod +x /usr/bin/CP; sudo touch /usr/bin/CP
gedit admin:///usr/bin/CP 

在gedit中，粘贴CP实用程序并保存:

#!/bin/bash
#Regular cp works with the assumption that the destination path exists and if it doesn't, it will verify that it's parent directory does.

#eg: cp /a/b /c/d will give /c/d/b if folder path /c/d already exists but will give /c/d (where d is renamed copy of b) if /c/d doesn't exists but /c does.

#CP works differently, provided that d in /c/d isn't an existing file, it assumes that you're copying item into a folder path called /c/d and will create it if it doesn't exist. so CP /a/b /c/d will always give /c/d/b unless d is an existing file. If you put the --rename switch, it will assume that you're copying into /c and renaming the singl item you're copying from b to d at the destination. Again, if /c doesn't exist, it will be created. So CP --rename /a/b /c/d will give a /c/d and if there already a folder called /c/d, contents of b will be merged into d.

#mkdir -p /foo/bar && cp myfile "$_"

    \n This script (CP, note capital letters) is intended to supplement \

    \n Script's function is to check if the destination path exists \
    \n before starting the copy. If it doesn't it will be created.\n    
    \n To make this happen, CP assumes that the item you're copying is \
    \n being dropped in the destination path and is not the destination\
    \n itself (aka, a renamed copy of the source file/folder). Meaning:\n 
    \n * \"CP /a/b /c/d\" will result in /c/d/b \
    \n * even if you write \"CP /a/b /c/b\", CP will create the path /a/b, \
    \n   resulting in /c/b/b. \n
    \n Of course, if /c/b or /c/d are existing files and /a/b is also a\
    \n file, the existing destination file will simply be overwritten. \
    \n This behavior can be changed with the \"--rename\" switch. In this\
    \n case, it's assumed that \"CP --rename /a/b /c/d\" is copying b into /c  \
    \n and renaming the copy to d.\n

这么老的问题，但也许我可以提出另一种解决方案。

您可以使用安装程序复制您的文件，并“在飞行中”创建目标路径。

install -D file /path/to/copy/file/to/is/very/deep/there/file

不过，还是有一些方面需要考虑的:

您还需要指定目标文件名，而不仅仅是目标路径 目标文件将是可执行的(至少，从我的测试来看)

您可以通过添加-m选项来设置目标文件的权限来轻松修改#2(例如:-m 664将创建具有权限rw-rw-r——的目标文件，就像使用touch创建一个新文件一样)。
