Unix - 创建文件夹和文件的路径 [英] Unix - create path of folders and file

问题描述

我知道你可以用mkdir来创建一个目录和touch来创建一个文件，但是没有办法一次完成这两个操作吗?

I know you can do mkdir to create a directory and touch to create a file, but is there no way to do both operations in one go?

即如果我想在文件夹 other 不存在时执行以下操作:

i.e. if I want to do the below when the folder other does not exist:

cp /my/long/path/here/thing.txt /my/other/path/here/cpedthing.txt

错误:

cp: cannot create regular file `/my/other/path/here/cpedthing.txt': No such file or directory

有没有人想出一个函数来解决这个问题?

Has anyone come up with a function as a workaround for this?

推荐答案

使用 && 在一个 shell 行中组合两个命令:

Use && to combine two commands in one shell line:

COMMAND1 && COMMAND2
mkdir -p /my/other/path/here/ && touch /my/other/path/here/cpedthing.txt

注意:以前我建议使用 ; 来分隔这两个命令，但正如@trysis 指出的那样，在大多数情况下使用 && 可能更好，因为如果 COMMAND1 失败 COMMAND2 也不会被执行.(否则这可能会导致您可能没有预料到的问题.)

Note: Previously I recommended usage of ; to separate the two commands but as pointed out by @trysis it's probably better to use && in most situations because in case COMMAND1 fails COMMAND2 won't be executed either. (Otherwise this might lead to issues you might not have been expecting.)
