+# Change The Current Directory For psql
+
+When you start a `psql` session, your current directory is what `psql` will
+use as its current directory. This is important for meta-commands that use
+relative paths based on the current directory -- for instance, the `\i`
+meta-command for importing files.
+
+You can change the current directory within a `psql` session using the `\cd`
+meta-command.
+
+If my current directory is `home` and there is a `sql` directory in `home,
+these commands will do the following:
+
+```sql
+\! pwd
+/home
+\cd sql
+\! pwd
+/home/sql
+```
+
+The `\cd` meta-command even supports tab completion relative to the current
+directory.
+
+You can also change to your home directory using just `\cd`.
