 ## Git
+### Remove All Deleted Files from the Working Tree
+When you delete a lot of files using `/bin/rm` you can use the following command to remove them from the working tree and from the index, eliminating the need to remove each one individually:
+
+```bash
+$ git rm $(git ls-files -d)
+```
+
+For example:
+
+```bash
+$ git status
+On branch master
+Changes not staged for commit:
+	deleted:    a
+	deleted:    c
+	
+$ git rm $(git ls-files -d)
+rm 'a'
+rm 'c'
+
+$ git status
+On branch master
+Changes to be committed:
+	deleted:    a
+	deleted:    c
+```
+
