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