+# Partial String Matching In Bash Scripts
+
+To compare two strings in a bash script, you will have a snippet of code
+similar to the following:
+
+```bash
+if [[ $(pwd) == "/path/to/current/directory" ]]
+then
+  echo "You are in that directory";
+fi
+```
+
+You may only want to do a partial string match. For this, you can use the
+`*` wildcard symbol.
+
+```bash
+if [[ $(pwd) == *"directory"* ]]
+then
+  echo "You are in that directory";
+fi
+```
