如何获得卷曲保存到不同的目录？ [英] How to get CURL to save to a different directory?

问题描述

我需要能够在文件下载的URL传递，再加上文件的路径保存到。

I need to be able to pass in the URL of the file download, plus a path for the file to be saved to.

我认为这是与-O和-o上的卷曲，但我似乎无法找到答案。

I think it has something to do with -O and -o on CURL, but I can't seem to figure it out.

例如，这是我使用的是什么在我的bash脚本现在：

For example, this is what I'm using in my bash script now:

#!/bin/sh

getsrc(){
    curl -O $1
}

getsrc http://www.apache.org/dist/ant/binaries/apache-ant-1.7.1-bin.tar.gz

我怎样才能改变卷曲的语句，所以我可以做

How can I change the curl statement so I can do

getsrc http://www.apache.org/dist/ant/binaries/apache-ant-1.7.1-bin.tar.gz /usr/local

，并将它保存文件到/ usr /地方？

and have it save the file to /usr/local?

推荐答案

呜呜......你可能想要做的就是

Hum... what you probably want to do is

getsrc(){
    ( cd $2 > /dev/null ; curl -O $1 ; ) 
}

该-O（资本的O）说要存储在本地命名，如远程文件，但忽略了远程路径组件。为了能够在一个特定的目录来存储，最简单的办法是cd到它...而我呢，在一个子shell，所以DIR变化不会传播

The -O (capital O) says to store in a local named like the remote file, but to ignore the remote path component. To be able to store in a specific directory, the easiest way is to cd to it... and I do that in a sub-shell, so the dir change does not propagate
