+# Cron
+
+This will be particularly about `dcron` with Void Linux (i.e runit).
+
+## Jobs
+
+Syntax is:
+
+```
+%M %H %d %m %a command
+```
+
+Where `%?` is `date +format` specifiers (`%M` is minute, etc).
+
+Cron follows certain specifications,
+- * - is a wildcard which makes specifier be ignored.
+- [0-9]+ instead of * will make cron run at specified time.
+- [0-9]+`,`[0-9]+ will execute job at multiple specified times.
+- [0-9]+`-`[0-9]+ will limit execution between certain time (i.e every hour between 13-19).
+- *`/`[0-9]+ will run every N time period.
+- `@hourly`, `@daily`/`@midnight`, `@weekly`, `@monthly` and `@reboot` are shorthands, with hourly being `0 * * * *`.
+
+Command can be anything that shell can execute.
+
+You can access `$HOME`, `$USER`/`$LOGNAME`, `$SHELL` and `$PATH` environment variables. Which makes it possible to `. $HOME/.bashrc; $HOME/script.sh`
+
+## Examples
+
+> TODO: examples
+
+Verify environment,
+```
+* * * * * printenv > ~/cron_env_test.txt
+```
+
+## Commandline
+
+List,
+```
+crontab -l
+```
+
+Edit,
+```
+crontab -e
+```
+
+Remove **all**,
+```
+crontab -r
+```
+
+Replace with file,
+```
+crontab <filename>
+```
+
+Insert from stdin,
+```
+crontab -

+# Runit
+
+## Usage
+
+- sv status, sv s
+ > prints status of service
+- sv up, sv u
+ > start service, restart if stops
+- sv down, sv d
+ > stop service, do not restart
+- sv once, sv o
+ > start service, do not restart
+- sv pause, cont, hup, quit, term, kill
+ > restarts service
+- sv exit, sv e
+ > kill service, do not restart
+
+## User services
+
+Create a service named `runsvdir-<uname>` with `run` script containing:
+
+```bash
+#!/bin/sh
+
+export USER="<uname>"
+export HOME="/home/<uname>"
+
+groups="$(id -Gn "$USER" | tr ' ' ':')"
+svdir="$HOME/<servicedir>"
+
+exec chpst -u "$USER:$groups" runsvdir "$svdir"
+```
+
+Afterwards you can export `SVDIR="$HOME/<servicedir>"` for convenience.
+
+## Service management
+
+### Service structure
+
+```
+*run - (mandatory) starts process
+*check - exit 0 means service is running
+*finish - is ran after any shutdown (for cleanup)
+control/
+├── *c - replaces SIGCONT
+├── *d - is ran after control/t for down
+├── *x - is ran after control/t for exit
+├── *t - replaces SIGTERM
+└── *u - is ran before run
+log/ - managed by sv, contains logs
+supervise/ - managed by sv
+```
+
+### Files
+
+#### run
+
+Mandatory (everything else is optional) script that is ran to start the service.
+
+#### check
+
+Script that performs manual check of service status and returns `0` if service is up and running or any non-zero code otherwise.
+
+#### finish
+
+A cleanup script. Is ran last after service is terminated by any means, including crashes.
+
+#### control/d and control/x
+
+Ran after `SIG____` when `sv` is called with either `down` or `exit` respectively.
+
+#### control/t, control/c, control/h, etc
+
+Scripts that replace `SIGTERM`, `SIGCONT` and `SIGHUP` respectively. Can be used to control the way that service is shut down. If they fail to stop service then they must exit with any non-zero code.
+
+The letter comes from first letter that comes after `SIG`.
+
+#### control/u
+
+Ran when `sv` is called with `up` before the `run` script.
+
+### Using with screen
+
+#### Run
+
+```bash
+#!/bin/sh
+
+# exec seems to be crucial
+exec screen -DmS session_name program
+```
+
+#### Stop, term and down
+
+```bash
+#!/bin/sh
+
+screen -S session_name -X kill
+# or if needs to be terminated with command
+screen -S session_name -X stuff stop
+
+sleep 5
+```
+
+### Do not autostart
+
+Create `/path/to/service/down`
+
+### Fast check status as exit code
+
+```bash
+sv status devdocs | perl -ne 'exit(/^run:/gi ? 0 : 1)' && $() || $()
+```
