+## Unexpected start of line. If breaking lines, |/||/&& should be at the end of the previous one.
+
+### Problematic code:
+
+```sh
+dmesg
+  | grep "error"
+```
+
+### Correct code:
+
+```sh
+dmesg |
+  grep "error"
+```
+
+### Rationale:
+
+ShellCheck has found a line that unexpectedly started with `|`, `||` or `&&`. This usually happens when a line is broken incorrectly.
+
+When breaking around a `|`, `||` or `&&`, there are two options:
+
+* Break the line *after* this token. `dmesg` is a complete command by itself, but `dmesg |` is not so the shell knows to continue on the next line.
+* Use a `\` at the end of the previous line to explicitly tell the shell to continue on the next.
+
+### Exceptions:
+
+None. This is a syntax error.
