+# Network Database
+
+I have a half-baked plan to finally make use of plain-text databases, and it's already half-working.
+Try these commands:
+
+Ask what types of _rec_ords it contains:
+
+## Database
+
+```sh
+recinf network.rec
+```
+
+### Select queries
+
+Select with `recsel`, then specify the database (.rec) and type of record (like table in db).
+
+`--include-descriptors` or `-d`
+`--type` or `-t`
+`--expression` or `-e`
+`--quick` or `-q`
+
+```sh
+recsel network.rec --type router
+recsel network.rec -d -t lxc
+recsel network.rec -d -t lxc -e ?example?
+```
+
+User `-q` for a `--quick` selection, or `-e` for more precise selections.
+
+```sh
+recsel network.rec --type lxc --quick wiki
+recsel network.rec -t lxc -q nginx
+recsel network.rec -t lxc -e "name ~ 'nginx'"
+recsel network.rec -t lxc -e "name = 'nginx12'"
+```
+
+### Insert queries
+
+Insert a new record with `recins`.
+
+```sh
+recins network.rec -t lxc -r "name: bob" -r "service: bob" -r "host: moxx"
+```
+
+### Update queries
+
+If you can select something, you can also set its fields with `recset`.
+
+Use `-f` to set the `--field`, and `-a` to `--add`, or `-s` to `--set`.
+
+
+```sh
+recset network.rec -t lxc -e "name = 'nginx12'" -f proxies -a soft-serve
+recsel network.rec -t lxc -e "name = 'nginx11'" -p proxies[0]
+recset network.rec -t lxc -e" name = 'nginx11'" -f proxies[0] -s wiki9
+```
