How to use ']' in the upper bound of a range character set

[Arlinta Barus]

Hi,

I try to use ']' as the upper bound of a range character set, such as:
grep -E "[1-\]]" file_input    or
grep -E "[1-\\]]" file_input   or
grep -E "[1-]]" file_input

but it doesn't work. Anyone can help me, please ?

Thanks.

Cheers,
Arlinta
