     If you want to use the `vb_omit_contigs_tmp.txt` as the search pattern to omit contigs from the bins, you can do that following:
 
-    ```bash
-    module purge
-    module load SeqKit/2.4.0
+    !!! terminal "code"
 
-    for bins in mock_bins/*.fna; do
-        seqkit grep -v -f vb_omit_contigs.tmp.txt > refined_bins/$(basename ${bins} .fna).refined.fna
-    done
-    ```

+        module purge
+        module load SeqKit/2.4.0
+
+        for bins in mock_bins/*.fna; do
+            seqkit grep -v -f vb_omit_contigs.tmp.txt > refined_bins/$(basename ${bins} .fna).refined.fna
+        done
+        ```
 
     In the code above, we added a `-v` to the `grep` command to indicate invert matches.
