 ```bash
-echo '39 */3 * * * /usr/bin/updatedb' > "$USER".cron

+```
+
+You can put this in a file and edit it:

 The `cron` program will check your syntax before adding the tab.
 
 Your crontab file sits somewhere in `/var/spool/`.

-### Full Paths
+### Variables
+
+`cronie` doesn't know where you live, so to put something in your `$HOME` directory, you have to tell it:
 
-Executing something requires the full path to where it is, so you cannot simply use `apt update -y`, because cron does not know where `apt` is.
-Instead, find out where it is:
 
 ```bash
-type -P apt
+echo "HOME=$HOME" > $filename
+crontab -l >> $filename
+crontab $filename
 ```
 
-`/usr/bin/apt`
+`cronie` doesn't know where anything lives, including programs.
+You can give it your usual `$PATH` variable like this:
 
-Then put that into the crontab:
 
 ```bash
-sudo crontab -e
+echo $PATH > $filename
+crontab -l >> $filename
+crontab $filename
 ```
 
-> 40 */3 * * * /usr/bin/apt update -y
+Now instead of doing this
 
-This will run `apt update -y` as root every 3 hours, at 40 minutes past the hour, e.g. 00:40, 03:40, 06:40.
+`40 */3 * * * /usr/bin/du -sh $HOME/* | sort -h > $HOME/sum.txt`
 
-## Directories
+You can simply do this:

+`40 */3 * * * du -sh $HOME/* | sort -h > $HOME/sum.txt`
+
+## Run as Root
 
 You can execute a script as root by putting it into a directory, instead of in the tab.
 Look at the available cron directories:
 
 ```bash
-ls /etc/cron.\*
+ls -d /etc/cron.*
+```
+
+Make a script which runs daily:

+```bash

-## Tips
-
-### Variables
-
-Add your `$HOME` to crontab to use scripts.
-First add `HOME=/home/$USER`, then you can use syntax like this:
-
-0 * * * * $HOME/.scripts/myScript.sh
-
-*Remember to test the script by executing that line first*:
-
-```bash
-$HOME/.scripts/myScript.sh
-```
-You can also add your regular path to your crontab as a variable (see example below).
-If you're using vim as the editor, just run this at the top of your crontab:
-
-```bash
-:r!echo PATH=$PATH
-```
+# Troubleshooting
 
 ### `date` Commands
 
 Cron doesn't understand the `%` sign, so if you want to use `date +%R`, then it should be escaped with a backslash: `date +\%R`.
 
-### File Location
-
-The crontab files are in `/var/spool/cron/`, so you can backup or restore them.
-
-# Example
-
-```
-HOME=/home/user
-PATH=/usr/condabin:/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl:/home/user/.local/bin:/home/user/.scripts/:/home/user/.local/bin:/home/user/.scripts/

+This utility is largely useless, as it can only identify people by their email.
+So if someone has multiple GPG keys associated with one email, the tool will not work.

+Worse than not working, it may 'suddenly' stop working as you try to transfer a secret to someone, who then discovers that `git-secret` requires them to mess about with their GPG keyring in order to use the repository.
