OSX : absolute desktop file path ? (including /Volumes)
提问by AntoineG
When I try to retrieve the path of a file on my desktop, I get :
当我尝试检索桌面上文件的路径时，我得到：
/Users/MyName/Desktop/file.txt
But I need the full path (to feed a bash script):
但我需要完整路径（以提供 bash 脚本）：
/Volumes/MyDrive/Users/MyName/Desktop/file.txt
I spent quite some time searching for a solution, but couldn't find any. I'm open to anything that can be run through Automator, bash or applescript.
我花了很长时间寻找解决方案，但找不到任何解决方案。我对任何可以通过 Automator、bash 或 applescript 运行的东西持开放态度。
It makes me crazy because if I simply drop my file.txt in Coda, it will output the full absolute path I want, right away, whereas Terminal won't.
这让我很抓狂，因为如果我简单地将我的 file.txt 放在 Coda 中，它会立即输出我想要的完整绝对路径，而 Terminal 不会。
Any ideas ?
有任何想法吗 ？

So you need to find which volume under /Volumesis equivalent to /, yes? That's easy - just look for the symlink to /.
所以你需要找到下哪个体积/Volumes相当于/，是吗？这很简单 - 只需查找 / 的符号链接即可。
for vol in /Volumes/*; do
if [ "$(readlink "$vol")" = / ]; then
root_vol=$vol
fi
done
Then you can do
然后你可以做
echo "$root_vol$HOME/Desktop/file.txt"
or whatever.
管他呢。

For anyone who might need it : if you're running an OSX Automator workflow/application/service and needs an absolute path to your input file, simply add a "Run shell script" action, set the input "as arguments" and use the following :
对于可能需要它的任何人：如果您正在运行 OSX Automator 工作流/应用程序/服务并且需要输入文件的绝对路径，只需添加一个“运行 shell 脚本”操作，将输入设置为“作为参数”并使用下列的 ：
#!/bin/bash
## Check if the input is an absolute path including the volume name
if [[ "" = /Volumes/* ]]
## If TRUE, the path is already correct
then
echo ""
## If FALSE, needs fixing
else
## Resolve the volume name
## by looping through all the volumes to find the one symlinked to "/"
for vol in /Volumes/*
do
if [ "$(readlink "$vol")" = / ]
then root_vol=$vol
fi
done
## Pass the path back to Automator for further use
echo "$root_vol"
fi
