+=== && AND Operator ===
+This control operator tells bash to run a second command **only if the first command before it succeeded**.
+If the first command fails, the second command is entirely skipped.
+**Example**
+<code bash>
+$ rm hello.txt && echo "Deleted file."
+rm: cannot remove 'hello.txt': No such file or directory
+</code>
+Because the file did not exist, the ''echo'' command was not run.
