+==== Method 2 ====
+Add this function to your ''.bashrc'' file:
+<code>
+## spack command wrapper, so we can include our own `spack something`
+## commands, like `spack search`:
+spack () {
+    case "$1" in
+        "search")
+            python3 /opt/sw/spack-scripts/search/search.py "$2"
+            ;;
+        *)
+            command spack "$@"
+    esac
+}
+</code>
+Usage example:
+<code>
+skylake [user@l41 ~]$ spack search asd
+==> The package hash asd refers to python and belongs to vsc4 as:
+     python +bz2+ctypes+dbm~debug+libxml2+lzma~nis~optimizations+pic+pyexpat+pythoncmd+readline+shared+sqlite3+ssl~tix~tkinter~ucs4+uuid+zlib
