bash变量路径名中的空格

Question

啊.我讨厌bash转义序列.这样做的正确方法是什么？

$ export SUBLPKG=~/"Library/Application Support/Sublime Text 2/Packages"
$ cd $SUBLPKG
-bash: cd: /Users/$ME/Library/Application: No such file or directory


$ export SUBLPKG=~/"Library/Application\ Support/Sublime\ Text\ 2/Packages"
$echo $SUBLPKG
/Users/$ME/Library/Application\ Support/Sublime\ Text\ 2/Packages
$ cd $SUBLPKG
-bash: cd: /Users/$ME/Library/Application\: No such file or directory

我想打破所有的事情.

gaaaaaahhhhhhhhhhhhhhhhhh.

正确的方法是在扩展时引用变量,否则会在空格上发生单词拆分:

export SUBLPKG=~/"Library/Application Support/Sublime Text 2/Packages"
cd "$SUBLPKG"

您可能还想在手册中引用Word Splitting.
