bash string equality
bash, equality, equals
Solution
There's no difference, `==` is a synonym for `=` (for the C/C++ people, I assume). See here, for example.
You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.
Problem
In `bash`, what's the difference, if any, between the equal and double equal test operators? ``` [[ "a" = "a" ]] && echo equal || echo not-equal [[ "a" == "a" ]] && echo equal || echo not-equal [[ "a" = "b" ]] && echo equal || echo not-equal [[ "a" == "b" ]] && echo equal || echo not-equal ``` results in: ``` equal equal not-equal not-equal ```
