为具有包含空间的文件名的路径在~.bash_profile中导出别名

Question

我试图在Mac中的bash_profile中添加一个别名。我试图创建别名的文件的实际路径是

amar@admin:~/Library/Application Support/com.bohemiancoding.sketch3/Plugins 

$pwd

/Users/amar/Library/Application Support/com.bohemiancoding.sketch3/Plugins

我试过两种选择

选项# 1

export sketch="/Users/amar/Library/Application\ Support/com.bohemiancoding.sketch3/Plugins"

这有错误，比如

amar@admin:~$ echo $sketch
/Users/amar/Library/Application\ Support/com.bohemiancoding.sketch3/Plugins
amar@admin:~$ cd $sketch
-bash: cd: /Users/amar/Library/Application\: No such file or directory

选项2

export sketch="/Users/amar/Library/Application Support/com.bohemiancoding.sketch3/Plugins"

这显示了错误，如

amar@admin:~$ echo $sketch
/Users/amar/Library/Application Support/com.bohemiancoding.sketch3/Plugins
amar@admin:~$ cd $sketch
-bash: cd: /Users/amar/Library/Application: No such file or directory

问题在此文件名Application Support附近。

Answer 1

展开变量时必须引用该变量：

sketch="/Users/amar/Library/Application Support/com.bohemiancoding.sketch3/Plugins"
cd "$sketch"

引用不是可选的，你也无法避免它。
