Each category - sound/, networking/, et c. - now has its own little
database in .dbs/.  So the database only recompiles based on categories,
rather than a complete recompile every time a single file changes.

-# Linux Knowledgebase
+The Linux Knowledge-Base provides quick-start guides for working with terminal programs.
 
-This is a list of quickstart guides for Linux programs, designed to get the user up and running as fast as possible.
+# Setup
+
+Install `make`, `recutils`, and any fuzzy-finder (i.e. `sk`, `fzy`, or `fzf`).
+
+## Usage
+
+
+```sh
+make
+make database
+
+recsel db.rec -q database
+recsel db.rec -q gpg
+recsel db.rec -e "title = 'ssh'"
+recsel db.rec -e "title ~ 'ssh'"
+recsel db.rec -e "title ~ 'bash'" -R title,wordcount
+```
 
 # Style
 
-## Praxis Only
+## No History, No Context
 
-We leave theory alone as much as possible.
+- Nobody cares about how the project started.
-The documentation should be of the form 'if you want *X*, type *Y*'.
+- Nobody wants to read what `ffmpeg` is, because anyone who wants to use it already knows what it is.
 
-We don't need to explain what a program does - anyone looking up 'how to X', already knows what they want to do.
+## Be Opinionated
-We don't even need to explain which program to use - if someone wants to combine an mp4 and webm video into a single video file, they only care about that result, not about learning `ffmpeg`.
 
-Any interest in these tools only comes after we can use them.
+- Guides should not ask the reader to select options half-way through.
+- Options for different filesystems, databases, et c., should be written as separate guides.
 
-## Chronological
+## Repetition Beats Reference
 
-Entries should read like scripts - everything in the right order, with small notes on what this does.
+If a database requires three commands to set up, it's better to repeat those three commands for every program that requires a database than to just link to another file which discusses databases.
 
-The chronology should never branch.
+## Show Arguments as Variables
-If `gitea` can use three different types of database, the documentation should simply pick one and continue instructions from there.
-Repetition works better than a reference - if a database requires three commands to set up, it's better to repeat those three commands for every program that requires a database than to just link to another file which discusses databases.
 
----
+Look at this line:
 
-### Closing
+```sh
-
+grep ls --color=always  $HISTFILE | less -R
-Introductory documents should show anything required to cleanly uninstall a program, without leaving bulky configuration files behind.
-
-## Three Input Types
-
-There are three types of examples:
-
-Fixed input:
-
-```bash
-ls
 ```
 
-Anything with arbitrary input should be shown as a variable.
+What else can go in place of `always`?
+Can you say `--color=red`?
+Can you put anything?
+The answer is not obvious.
 
-```bash
+What about this line:
-ls $FILE
+
+```sh
+git branch new
+git checkout new
 ```
 
-Non-commands (e.g. output) should be shown as quoted text:
+Do you always use `new`?
+Can you use another word here?
+The answer is not obvious.
 
-> LK           img

 # Type
 
 `type` shows what kind of thing you're running, be it an alias, function, or binary program.
 
-```bash
+```sh
-type cmus
+type cd
+type ls
+type -P ls
+type -a cat
 ```
 
-![where is cmus?](/tapes/which.gif)
-
 # Whereis the Program
 
-Ask where the `angband` program is, along with all its configuration files:
+Where is `grep` and all its configuration files?
 
-`whereis angband`
+```sh
-
+whereis grep
-Also `which` shows where a binary file (the program) is, 
-
-```bash
-which cmus
 ```
 
-# Search Instantly with `plocate`
+Which one of these is the binary file which you actually use?
 
-You can search every file on the computer instantly by installing `plocate`.
+```sh
-
+which grep
-Once installed, run `sudo updatedb` to create the database of (nearly) every file on the computer.
-
-Check how big the database is:
-
-```bash
-du -h /var/lib/plocate/plocate.db
 ```
 
-Once you have the database, you can find nearly any file instantly.
+# More
 
-- Search for gifs: `locate .gif`
+- [Search instantly with `plocate`](data/search_system.md)
-- Search for gifs in the `/usr/` directory: `locate /usr/ .gif`
-- Search for jpg images with 'dog' or 'Dog' in the name: `locate -i dog jpg`
-- Search for videos: `plocate --regex '.mp4$|.mkv$|.wmv$|.webm$|.mov$|.avi$'`
-
-For best results, run `updatedb` regularly, perhaps in [crontab](../system/cron.md).
-
-## Search More Places
-
-`plocate` will not search `/tmp/`, because nobody cares about those files, and won't search inside `/mnt/`, because that's where USB sticks get mounted, so the files keep changing as USB sticks come and go.
-
-Change where `plocate` searches by editing the configuration file at `/etc/updatedb.conf`.
-
-By default, the `/mnt` directory is 'pruned' from the database.
-So if you want to search `/mnt` for videos, remove the word `/mnt` from the configuration file.
-
-
-```bash
-cat /etc/updatedb.conf
-sudo sed 's#/mnt/##' /etc/updatedb.conf
-sudo updatedb
-plocate --regex '.mp4$|.mkv$|.wmv$|.webm$|.mov$|.avi$'

+
+You can play with a board games database from boardgamegeek.com.
+
+## Download the Database
+
+```sh
+mkdir board_games
+cd board_games
+curl -Lo bg.zip 'https://www.kaggle.com/api/v1/datasets/download/threnjen/board-games-database-from-boardgamegeek'
+unzip bg.zip
+```
+
+The header line shows fields with a bunch of colons, which will confused `recutils`, so we'll have to get rid of them.
+
+```sh
+sed -i '1s/://g' *.csv 
+```
+
+Convert the games to `.rec` format.
+
+```sh
+csv2rec games.csv > games.rec
+```
+
+## Queries
+
+If you try to look at older games, you'll find lots of results.
+
+```sh
+recsel games.rec -e "YearPublished < 1800" -c
+recsel games.rec -e "YearPublished < 1800" -Cp Name
+```
+But most are wrong.
+The problem is games with a `YearPublished` date of `0`, probably because the year published is unknown.
+
+```sh
+recsel games.rec -e "Name = 'The Goblin King is Angry'" -p YearPublished
+```
+
+Fix the query by removing games published in '0 AD'.
+
+```sh
+recsel games.rec -e "YearPublished < 1800 && YearPublished != 0" -R YearPublished,Name
+```
+
+Or fix the database setting `YearPublished` to 'unknown':
+
+```sh
+recsel games.rec -e "YearPublished = 0" -Cp Name
+recset games.rec -e "YearPublished = 0" -f "YearPublished" -S 'unknown'
+```
+
+Strategic games which work best with 3 players, sorted by Average Rating:
+
+```sh
+recsel games.rec -e "BestPlayers = 3 && CatStrategy = 1" -CR Name --sort=AvgRating
+```

+## Create
+
+Make a database for your boardgames, specifying only one field and value:
+
+```bash
+database=games.rec
+n=Name
+g=Vojvodina
+touch $database
+recins -f $n --value $g $database
+recsel $database
+```
+
+Insert a few more, with the estimated playtime:
+
+```bash
+recins -f Name -v Saboter -f Playtime -v 30 $database
+recins -f Name -v Chess -f Playtime -v 30 $database
+```
+
+View all games, or select one by number:
+
+```bash
+recsel $database
+recsel -n 0 $database
+```
+
+Each game should note whether or not you have played it yet, so you can add that field and set the default to `yes`.
+
+```bash
+f=played
+v=yes
+recset -f $f -a $v $database
+```
+
+...but the field is wrong, it should have a capital letter:
+
+```bash
+new_field=Played
+recset -f $f --rename $new_field
+```
+
+## Read
+
+Check how many records the database has:
+
+```bash
+recinf $database
+```
+
+Look at just the games you've never played:
+
+```bash
+recsel --expression="Played = 'no'" $database
+```
+
+Print how many, then just print the names:
+
+```bash
+recsel -e "Played = 'no'" --count $database
+recsel -e "Played = 'no'" --print=Name $database
+```
+
+## Update
+
+To change a game's `Played` field from `no` to `yes`, use `recset` to specify the number, and change that field.
+
+```bash
+num=0
+f=Played
+value=yes
+recsel --number=$num $database
+recset --number=$num -f $f --set=$value $database
+```
+
+Find all games with a playtime of `30`, and set the field `Max_Players` to `4`.
+
+```bash
+recset -e "Playtime = 40" -f Max_Players --set 50 games.rec
+```
+
+This doesn't work, because that field does not exist.
+You can `--set-add` the field, to add it wherever it does not exist.
+
+```bash
+recset -e "Playtime = 40" -f Max_Players --set-add 50 games.rec
+```
+
+## Delete
+
+Remove `Played` record from first game:
+
+```bash
+num=0
+recset --number=$num -f Played --delete $database
+```
+
+You can comment the line instead of deleting it:
+
+```bash
+num=1
+recset --number=$num -f Played --delete $database
+recsel $database
+cat $database
+```
+
+Delete an entire record:
+
+```bash
+num=2
+recdel --number=$num $database
+```

+
+You can search every file on the computer instantly by installing `plocate`.
+
+Once installed, run `sudo updatedb` to create the database of (nearly) every file on the computer.
+
+Check how big the database is:
+
+```sh
+du -h /var/lib/plocate/plocate.db
+```
+
+Once you have the database, you can find nearly any file instantly.
+
+- Search for gifs: `locate .gif`
+- Search for gifs in the `/usr/` directory: `locate /usr/ .gif`
+- Search for jpg images with 'dog' or 'Dog' in the name: `locate -i dog jpg`
+- Search for videos: `plocate --regex '.mp4$|.mkv$|.wmv$|.webm$|.mov$|.avi$'`
+
+For best results, run `updatedb` regularly, perhaps in [crontab](../system/cron.md).
+
+## Search More Places
+
+`plocate` will not search `/tmp/`, because nobody cares about those files, and won't search inside `/mnt/`, because that's where USB sticks get mounted, so the files keep changing as USB sticks come and go.
+
+Change where `plocate` searches by editing the configuration file at `/etc/updatedb.conf`.
+
+By default, the `/mnt` directory is 'pruned' from the database.
+So if you want to search `/mnt` for videos, remove the word `/mnt` from the configuration file.
+
+
+```bash
+su root
+cat /etc/updatedb.conf
+sed -i 's#/mnt/##' /etc/updatedb.conf
+updatedb
+exit
+```
+
+Now you can search in `/mnt` for films:
+
+```sh
+plocate --regex '.mp4$|.mkv$|.wmv$|.webm$|.mov$|.avi$'
+```
