+## Ignoring errors
+
+To ignore a shellcheck error, you can do one of three things:
+
+### Ignoring one specific instance in a file
+
+Use a [[directive]] to disable a certain instance:
+
+    hexToAscii() {
+      # shellcheck disable=SC2059
+      printf "\x$1"
+    }
+
+### Ignoring errors in one specific run
+
+Use a `-e` flag to disable a specific error when running shellcheck:
+
+    $ shellcheck -e SC2059 myscript
+
+### Ignoring one type of error forever
+
+Set the `SHELLCHECK_OPTS` variable in your `.bashrc`, `/etc/profile` or equivalent:
+
+    export SHELLCHECK_OPTS="-e SC2059"
