How test for directory with single quote (') in the name (with find)?

[Peng Yu]

Hi,

The following code shows that if a directory has single quote in the
name, it does not work. Does anybody know what the correct way is to
use -exec to test when there is single quote in the command? Thanks.

/tmp/tryfind$ find . -type f
./'/.export
/tmp/tryfind$ find . -type d -exec sh -c "test -d '{}'/.export" ';' -print
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file
