+# Bash Commands
+
+## Find
+### Find and delete
+Find and delete command
+```bash
+find / -name .DS_Store -delete
+```
+
+Alternative find and delete command
+```bash
+find / -name ".DS_Store" -exec rm {} \;
+```
+the previous command is due that not all `find` have a delete funcion but with overhead of new process `-exec`.
+
+Find and delete with no overhead
+```bash
+find / -name .DS_Store -print0 | xargs -0 rm
+```
