SC2130

-eq is for integer comparisons. Use = instead.

Note: This warning seems replace by SC2170 or SC2309. Removed in V0.4.2 - 2016-01-10

Problematic code:

[[ $foo -eq "Y" ]]

Correct code:

[[ $foo = "Y" ]]

Rationale:

Shells have two sets of comparison operators: for integers (-eq, -gt, ...) and strings (=, >, ...). ShellCheck has noticed that you're using an integer comparison with string data.

If you are in fact comparing integers, double check your parameters. Certain mistakes like $$foo or ${bar}} can introduce non-numeric characters into otherwise numeric arguments.

Exceptions

None.
