+# General file operations and utilities
+
+## `shred`
+
+Overwrites a file repeatedly with random data, to prevent data recovery.
+
+* `-z`: zeroes out at the end
+* `-n <N>`: does `N` iterations (deafults to only 3)
+* `-u`: deallocates and removes file
+
+So a common usage:
+
+    shred -zun100 <file>
