- x='a]'
- #
- # \] is not a valid escape for ] in set glob expression.
- # Glob sets have no escaping at all:
- # ] can be in a set if it is the first char: []abc],
- # dash can be in a set if it is first or last: [abc-],
- # [ and \ need no protections at all: [a[b\c] is a valid set of 5 chars.
- #
- # bash-4.3.43 misinterprets [a\]] as "set of 'a' or ']'".
- # Correct interpretation is "set of 'a' or '\', followed by ']'".
- #
- echo Nothing:${x#[a\]]}
- echo Nothing:"${x#[a\]]}"
- echo Nothing:${x%[a\]]}
- echo Nothing:"${x%[a\]]}"
- echo Ok:$?
