expression1 (IS GREATER-EQUAL | >=) expression2

Logical operator indicating "greater than or equal to". Can also be substituted with the punctuation operator >=. The result is true if the first numeric expression is equal to or greater than the second, and false otherwise. isnt greater-equal reverses these results.

isnt greater-equal has the same usage as is less-than (<).

For example:

  do when a >=b
  ...
  done
