 * Send email notification if command fails with [de-p1st-execNotify](src/de/p1st/exec_notify/execNotify.py).
 * Send unconditional notifications with [de-p1st-notify](src/de/p1st/exec_notify/notify.py).
 
+## TODOs
+
+~~* Send notification about unread local mail only once!~~
+* Rename python module (and git repository?) to `exec-notify`
+* Use subprocess_util > execute_print_capture
+  * This way, the user can see the stdout/stderr while it is executed
+  * And we can email the stdout/stderr if the process has failed
+
+* New program flow:
+  * Read configuration from `/etc/exec-notify` -> `work_dir` (default: `~/exec-notify`)
+  * Create file `$work_dir` / `$start_date-$id.args` with `$args` as content, e.g. `ls foo bar`
+
+  * If one or more .exit_code files exists and `$end_date` of at least one .exit_code file is older than 1 minute, then try to send email
+    * If email was sent:
+      * delete corresponding .exit_code, .stdout, .stderr, .args
+      * continue
+    * Else:
+      * continue
+
+  * Execute `$args` and redirect stdout/stderr to `$work_dir` / `$start_date-$id.{stdout,stderr}`
+  * If error occurred, create file `$work_dir` / `$start_date-$id-$end-date.exit_code` with content `$exit_code`
+    * Then, send email and if successful delete .exit_code file
+  * Delete .args, .stdout, .stderr files
+  * If error was reported, exit(1), else exit(0)
