OSX Bash 脚本使用名称中带有空格的文件/文件夹

OSX Bash Script working with Files/Folders with spaces in the name

提问by John Cleary

I'm trying to build a BASH script on OS X (10.6/10.7) to process a folder called QCExports which has folders with people's names in it in the format "LAST, First", i.e. "BOND, James".

我正在尝试在 OS X (10.6/10.7) 上构建一个 BASH 脚本来处理一个名为 QCExports 的文件夹，该文件夹包含以“LAST, First”格式，即“BOND, James”格式的人名文件夹。

When I run the following script, everything works but it falls over on folder or filenames with a space in them.

当我运行以下脚本时，一切正常，但它落在文件夹或文件名上，其中包含空格。

Script Code:

脚本代码：

#!/bin/bash
echo "QuickCeph Export Script"

#Set Path to Process & Paths to Copy To
pathToQCExports=/Users/myuser/Desktop/QCExports
sureSmilePath=/Users/myuser/Desktop/QCExportsForSureSmile
sesamePath=/Users/myuser/Desktop/QCExportsForSesame
blankReplace=""

#Process Each Name
find $pathToQCExports -type d | while read name ; do

    #escaping the folder with a space in the name
nameParsed=${name/", "/",\ "}

    echo "Processing: "$nameParsed  
    pathSureSmile=${nameParsed/$pathToQCExports/$sureSmilePath}
    pathSesame=${nameParsed/$pathToQCExports/$sesamePath}
    mkdir $pathSesame
    mkdir $pathSureSmile

    echo "Folders Created"

    #Copy For SureSmile 
    echo ${pathSureSmile}"/Suresmile-Frontal\ Photo.jpg" ${pathSureSmile}"/Suresmile-Frontal\ Photo.jpg"
    #cp `${$pathSureSmile}"/Suresmile-Frontal\ Photo.jpg" ${pathSureSmile}"/Suresmile-Frontal\ Photo.jpg"`

    #Copy For Sesame
    echo ${pathSesame}"/Suresmile-Frontal\ Photo.jpg" ${pathSesame}"/S02.jpg"
    #cp `${pathSesame}"/Suresmile-Frontal\ Photo.jpg" ${pathSesame}"/S02.jpg"`

done

echo "Completed";

Output:

输出：

QuickCeph Export Script
Processing: /Users/myuser/Desktop/QCExports/BOND,\ James
mkdir /Users/myuser/Desktop/QCExportsForSesame/BOND,\ James
mkdir: James: File exists
mkdir /Users/myuser/Desktop/QCExportsForSureSmile/BOND,\ James
mkdir: James: File exists
Folders Created
/Users/myuser/Desktop/QCExportsForSureSmile/BOND,\ James/Suresmile-Frontal\ Photo.jpg /Users/myuser/Desktop/QCExportsForSureSmile/BOND,\ James/Suresmile-Frontal\ Photo.jpg
/Users/myuser/Desktop/QCExportsForSesame/BOND,\ James/Suresmile-Frontal\ Photo.jpg /Users/myuser/Desktop/QCExportsForSesame/BOND,\ James/S02.jpg
Completed

On OS X usually in the terminal, you use a \ to escape a space in a folder or filename, but that doesn't seem to work.

在 OS X 上，通常在终端中，您使用 \ 来转义文件夹或文件名中的空格，但这似乎不起作用。

I notice that it's interpreting the spaces as a normal space would be interpreted on the command line and thinking I want to execute the command on two files - i.e. it's not passing the \ onwards. I end up with a folder called "Bond,\" and a folder called "James" in the folder I execute the script from.

我注意到它将空格解释为将在命令行上解释的普通空格，并认为我想在两个文件上执行该命令 - 即它没有向前传递 \。我最终在我执行脚本的文件夹中得到一个名为“Bond,\”的文件夹和一个名为“James”的文件夹。

Note, I deliberately have the cp commands # out at the moment, so they aren't being executed... the problem is the same for both creating the folders & copying the filenames.

请注意，我现在故意将 cp 命令 # 输出，所以它们没有被执行......创建文件夹和复制文件名的问题都是一样的。

If I copy and paste the "echo'd" version of these commands into a terminal window, the commands work! But when BASH executes them, it doesn't respect the . :(

如果我将这些命令的“echo'd”版本复制并粘贴到终端窗口中，这些命令将起作用！但是当 BASH 执行它们时，它不尊重 . :(

Any ideas?

有任何想法吗？

Thanks!! John

谢谢！！约翰

See my modifications on your script, you don't have to substitute spaces like you tried. Moreover, you must choose if you backslash the spaces or if you are using quotes. The simple way is to use double quotes. Good doc about quotes, see http://mywiki.wooledge.org/Quotesand http://wiki.bash-hackers.org/syntax/words

查看我对脚本的修改，您不必像尝试过的那样替换空格。此外，您必须选择是反斜杠空格还是使用引号。简单的方法是使用双引号。关于引号的好文档，请参阅http://mywiki.wooledge.org/Quotes和http://wiki.bash-hackers.org/syntax/words

#!/bin/bash
echo "QuickCeph Export Script"

#Set Path to Process & Paths to Copy To
pathToQCExports=/Users/myuser/Desktop/QCExports
sureSmilePath=/Users/myuser/Desktop/QCExportsForSureSmile
sesamePath=/Users/myuser/Desktop/QCExportsForSesame
blankReplace=""

#Process Each Name
find $pathToQCExports -type d | while read nameParsed ; do

    echo "Processing: $nameParsed"
    pathSureSmile="${nameParsed/$pathToQCExports/$sureSmilePath}"
    pathSesame="${nameParsed/$pathToQCExports/$sesamePath}"
    mkdir "$pathSesame"
    mkdir "$pathSureSmile"

    echo "Folders Created"

    #Copy For SureSmile 
    echo "${pathSureSmile}/Suresmile-Frontal Photo.jpg" "${pathSureSmile}/Suresmile-Frontal Photo.jpg"

    #Copy For Sesame
    echo "${pathSesame}/Suresmile-Frontal Photo.jpg" "${pathSesame}/S02.jpg"

done

echo "Completed"
