+## This is interpreted as a command name ending with apostrophe. Double check syntax.
+
+(also applies to multiple other characters like `.,([{<>}])#"'`) 
+
+### Problematic code:
+
+```sh
+var=$("wget 'http://www.shellcheck.net/'")
+echo Usage: $0 {start|stop|restart}
+array=val1, val2, val3
+
+```
+
+### Correct code:
+
+```sh
+var="$(wget 'http://www.shellcheck.net/')"
+echo "Usage: $0 {start|stop|restart}"
+array=(val1 val2 val3)
+```
+
+### Rationale:
+
+ShellCheck found a command name ending with a symbol, such as a comma, parenthesis, quote, or similar. This is almost always due to a syntax issue in the script.
+
+In the examples, bad quoting and invalid array syntax caused the shell to try to run commands ending in apostrophe, curly brace, and comma, respectively. 
+
+### Exceptions:
+
+If you have a command that *does* end in a symbol, you can ignore this message.
