sc, short for Spreadsheet Calculator, is a terminal based free spreadsheet program for Unix-based operating systems such as GNU/Linux and FreeBSD. It is similar to VisiCalc.
To run the program, type sc file.sc with whichever filename you want to create or modify.
When you first start it up, you should see a screen like this:
A B C D E F G
0 <
1
2
3
4
5
6
You can move the cursor around just like in vi, so j is down, k is up, h is left and l is right (once you memorize this it becomes much quicker than using cursor keys).
To insert left aligned text, move to the cell you want to put it in and press < followed by the text and then enter. Right aligned text works in the same way, using the > key.
Using right justify, you can come up with column headers and other text like this:
A B C D E F G
0 Part< Price Quantity Total
1
2 A-110
3 A-130
4 A-100B8
5
6 Grand total
Numbers are entered by moving to the appropriate cell, pressing =, typing in the number and pressing enter. This gives us the following:
A B C D E F G
0 Part Price Quantity Total
1
2 A-110 75.00< 1.00
3 A-130 46.00 1.00
4 A-100B8 3.00 6.00
5
6 Grand total
Now let's get rid of the decimal places for quantities as these are only going to be integers. To do this, go to the cell you want to be an integer and press F then # and enter.
A B C D E F G
0 Part Price Quantity Total
1
2 A-110 75.00 1<
3 A-130 46.00 1
4 A-100B8 3.00 6
5
6 Grand total
Next, we can specify the currency. Press F again, then $#,0.00;($#,0.00) and enter.
A B C D E F G
0 Part Price Quantity Total
1
2 A-110 $75.00 1
3 A-130 $46.00 1
4 A-100B8 $3.00 6
5
6 Grand total <
Now we let the program do maths for us. In cell D2, we can type =B2*C2 to make it work out what number should be in that cell, and so on.
A B C D E F G
0 Part Price Quantity Total
1
2 A-110 $75.00 1 75.00
3 A-130 $46.00 1 46.00
4 A-100B8 $3.00 6 18.00
5
6 Grand total <
Lastly, we can add up the totals to find out the grand total. In cell D6, simply type =@sum(D2:D4). After a bit more currency formatting, the spreadsheet is complete.
A B C D E F G
0 Part Price Quantity Total
1
2 A-110 $75.00 1 $75.00
3 A-130 $46.00 1 $46.00
4 A-100B8 $3.00 6 $18.00
5
6 Grand total $139.00<
You can then quit it by pressing q, and agree to update the file by pressing y. |
