This is a Unicode dash. Delete and retype as ASCII minus.

Problematic code:

[[ 3 –gt 2 ]] # Uses unicode en-dash character

Correct code:

[[ 3 -gt 2 ]] # Uses regular ASCII hyphen-minus character

Rationale:

A character that looks similar to - has made its way into your code. This is usually due to copy-pasting from blogs and other websites that formatted code as text, replacing the ASCII hyphen-minus with a Unicode dash character.

To fix it, simply delete and retype it.

For a large script, you can use your editor's Search&Replace by copy-pasting the bad dash.

Exceptions:

None. If you want a literal Unicode dash character, just quote it.
