+ Here is an example script, which removes the user's
+ cron, at and print jobs:
+ <programlisting>
+#! /bin/sh
+
+# Check for the required argument.
+if [ $# != 1 ]; then
+ echo "Usage: $0 username"
+ exit 1
+fi
+
+# Remove cron jobs.
+crontab -r -u $1
+
+# Remove at jobs.
+# Note that it will remove any jobs owned by the same UID,
+# even if it was shared by a different username.
+AT_SPOOL_DIR=/var/spool/cron/atjobs
+find $AT_SPOOL_DIR -name "[^.]*" -type f -user $1 -delete \;

+# Remove print jobs.
