tilde expansion in environment variable

Question

In my .sh file, I have this, cp $file $SOME_PATH, while $SOME_PATH is exported as export SOME_PATH="~/path/to/path/". But when I ran this .sh file, I got error message saying like no such "~/path/to/path/" exists. I replaced ~ as $HOME, then the error was gone. So what's up here with the tilde?

Thanks in advance.

use

SOME_PATH=~/path/to/path/

if you path have spaces, quote it

SOME_PATH=~/"path with spaces"

"path with space" -> path\ with\ space – Eric Towers Oct 21 '10 at 03:44

Remove the quotation marks on your export:

export SOME_PATH=~/path/to/path/

Thanks, but this seems not available, either. – dutor Oct 21 '10 at 03:44
Oh, sorry. Actually, I used cp $file "$SOME_PATH". ^_^ – dutor Oct 21 '10 at 03:46
Does it work with all quotation marks removed? You basically have to prevent literal interpretation. – chrisaycock Oct 21 '10 at 03:49
