sorting files while ignoring duplicates

[bluebonnet]

I want to sort a file(pudding) by the 1st column
but ignore all of the duplicates and output
the results to another file (prices).
For example,

sort +1 pudding > prices

the file looks like this..

Pudding Price

1 vanilla 1.05
2 strawberry 1.05
etc...

Oops! I need to add the word uniq to this equation.

Actually, if you want them sorted numerically, it should be...
[tt]
sort -n pudding | uniq > prices
[/tt]
Without the [tt]-n[/tt], they sort like...
[tt]
1 vanilla 1.05
10 peach 1.05
2 strawberry 1.05
20 chocolate 1.05
[/tt]
Whereas WITH the [tt]-n[/tt], they sort...
[tt]
1 vanilla 1.05
2 strawberry 1.05
10 peach 1.05
20 chocolate 1.05
[/tt]
Hope this helps.

sort -u does the same as uniq

I meant the sort it by the pudding column only.
Code is different. How would it look?

It would be +1.
would I printed out only the pudding section
and redirected it to another file?
How would that command look??
