问题描述
因此,如果我位于主目录中,并且想将foo.c移至〜/bar/baz/foo.c,但是这些目录不存在,则可以通过某种方法自动创建这些目录,这样您只需输入
So, if I'm in my home directory and I want to move foo.c to ~/bar/baz/foo.c , but those directories don't exist, is there some way to have those directories automatically created, so that you would only have to type
mv foo.c ~/bar/baz/
一切都会成功吗?看来您可以将mv命名为一个简单的bash脚本,该脚本将检查那些目录是否存在,如果不存在,则先调用mkdir然后再调用mv,但是我想我会检查是否有人有更好的主意.
and everything would work out? It seems like you could alias mv to a simple bash script that would check if those directories existed and if not would call mkdir and then mv, but I thought I'd check to see if anyone had a better idea.
推荐答案
这种单线(以bash表示)如何:
How about this one-liner (in bash):
mkdir --parents ./some/path/; mv yourfile.txt $_
打破现状:
mkdir --parents ./some/path
创建目录(包括所有中间目录),然后:
creates the directory (including all intermediate directories), after which:
mv yourfile.txt $_
将文件移动到该目录($ _扩展到传递到上一个shell命令的最后一个参数,即:新创建的目录).
moves the file to that directory ($_ expands to the last argument passed to the previous shell command, ie: the newly created directory).
我不确定这在其他shell中能用多远,但可能会为您提供一些有关查找内容的想法.
I am not sure how far this will work in other shells, but it might give you some ideas about what to look for.
以下是使用此技术的示例:
Here is an example using this technique:
$ > ls
$ > touch yourfile.txt
$ > ls
yourfile.txt
$ > mkdir --parents ./some/path/; mv yourfile.txt $_
$ > ls -F
some/
$ > ls some/path/
yourfile.txt
