[ast-users] [ksh93] `[[ foo == ~(E).* ]]' and `[[ foo == ~(E:.*) ]]' are not the same?

[Clark J. Wang]

See following example:

$ echo ${.sh.version}
Version jM 93u 2011-02-08
$ [[ FOO == ~(E).* ]] && echo yes || echo no
yes
$ [[ FOO == ~(E:.*) ]] && echo yes || echo no
no
$

But ~(i)foo and ~(i:foo) are the same:

$ [[ FOO == ~(i)foo ]] && echo yes || echo no
yes
$ [[ FOO == ~(i:foo) ]] && echo yes || echo no
yes
$
