It's admittedly extremely unlikely that the host platform name would contain special characters, but still use double quotes to pattern matching. Consider this script: #!/bin/bash bar="foobar" foo="foo*" [[ $bar == $foo ]] && echo "first true" [[ "$bar" == "$foo" ]] && echo "second true" We get the output: first true The plan is to move from first case to the second case to prevent pattern match where there shouldn't be any.
