+# Include Multiple Tables In A pg_dump
+
+When the `pg_dump` command is given the `-t` flag, it will dump just the table
+named with that flag. If you want to include multiple tables in the dump, you
+just need to use the flag multiple times.
+
+```bash
+$ pg_dump -t users -t users_roles -t roles my_database > roles.dump.sql
+```
+
+Alternatively, you can specify a
+[pattern](https://www.postgresql.org/docs/current/app-psql.html#APP-PSQL-PATTERNS)
+when using the `-t` flag.
+
+```bash
+$ pg_dump -t 'users*|roles' my_database > roles.dump.sql
+```
+
+You have to be a little more mindful of what will and won't be included when
+crafting a pattern. It is a nice shortcut for a well-known or well-constrained
+data model.
+
+See the [`pg_dump`
+docs](https://www.postgresql.org/docs/current/app-pgdump.html) for more
+details, as well as [some
+examples](https://www.postgresql.org/docs/current/app-pgdump.html#PG-DUMP-EXAMPLES).

+# Exclude A Command From The ZSH History File
+
+The `zsh` shell can be configured to record the commands you run from the
+terminal in a history file. This is great for recalling and retrieving past
+commands that you want to run again.
+
+What about commands that I don't want written to a file on my machine? For
+instance, if I'm running a command that includes a password, secret key, or
+some other sensitive value, I don't want that saved in plaintext on my machine.
+
+`zsh` has an affordance for this with the `hist_ignore_space` option. With that
+option enabled, any command preceded by a space (`' '`) will be excluded from
+the history file.
+
+First, turn it on.
+
+```zsh
+$ setopt hist_ignore_space
+```
+
+Now, try a couple commands and see what shows up in the file.
+
+```zsh
+$ echo 'this command will be saved in history'
+this command will be saved in history
+
+$  echo 'this will be kept secret'
+this will be kept secret
+
+$ tail ~/.zsh_history
+: 1654378676:0;echo 'this command will be saved in history'
+: 1654378690:0;tail ~/.zsh_history
+```
+
+Notice how the second command with the prefixed space is excluded.
