如何在路径上下文中使用“~"(波浪号)? [英] How do I use '~' (tilde) in the context of paths?
问题描述
我是一名 Web 应用程序开发新手.我有一个函数可以打开一个文件并读取它.不幸的是,测试服务器和生产服务器之间的目录结构不同.我被告知使用相对于 ~ 的路径".不过,我一直无法在~"上找到任何资源!
如何在路径上下文中使用波浪号?
这是在 Python 中.我使用 os.path.expanduser('~/path/in/home/area').
它是你在 UNIX 中的 $HOME
var,通常是 /home/username
.>
你的家"是指正在执行像 cd ~/MyDocuments/
这样的命令的用户的家是 cd/home/user_executing_cd_commnd/MyDocuments
I'm a web application development noob. I have a function that opens a file and reads it. Unfortunately, the directory structures between the test and production servers differ. I was told to "use a path relative to ~". I haven't been able to find any resources on the '~', though!
How do I use the tilde character in the context of paths?
EDIT: This is in Python. I fixed the problem, using os.path.expanduser('~/path/in/home/area').
it is your $HOME
var in UNIX, which usually is /home/username
.
"Your home" meaning the home of the user who's executing a command like cd ~/MyDocuments/
is cd /home/user_executing_cd_commnd/MyDocuments
