+====== 2022-06-04 - bash and RAII - continued ======
+couple days ago i wrote about [[:blog:2022:05:29:2022-05-29 - bash and RAII|RAII in bash]]. i forgot to mention 1 more thing there. when cleanup procedure is more complicated than simple ''rm -rf foobar'' it's worth to make it a separate function:
+<code bash>
+# ...
+function cleanup
+{
+  rm -rf "$VAR_TO_SANITIZE"
+  rm -fv /path/to/lock
+  umount /media/foobar
+}
+trap cleanup EXIT
+# ...
+</code>
