spaces in bash variable path name

问题

Ugh. I hate bash escape sequences. What's the proper way to do this?

$ 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

I want to break all the things.

gaaaaaahhhhhhhhhhhhhhhhhh.

回答1:

The proper way is to quote the variable while expanding else word splitting would happen on whitespaces:

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

You might also want to refer to Word Splitting in the manual.

Also refer to Word Splitting here.
