+# 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:
+
+```sh
+recinf network.rec
+```
+
+```sh
+recsel network.rec --type router
+recsel network.rec --include-descriptors --type lxc
+recsel network.rec -d -t lxc
+recsel network.rec -d -t lxc --expression
+recsel network.rec -t lxc --expression "name ~ 'nginx'"
+recsel network.rec -t lxc --expression "name = 'nginx12'"
+```
+
+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 --expression "name = 'nginx12'" -f proxies --add soft-serve
+recsel network.rec -t lxc --expression "name = 'nginx11'" -p proxies[0]
+recset network.rec -t lxc --expression "name = 'nginx11'" -f proxies[0] -s wiki9
+```
