Create range of values and count values.
Gents,

It is possible to generate a range of values according to column 1 and count the total of rows in the range.

example

input
Code:
15.3
15.5
15.8
15.9
16.0
16.1
16.8
17.0
17.5
18.0

output desired
Code:
15.0 - 15.9 = 4
16.0 - 16.9 = 3
17.0 - 17.9 = 2
18.0 - 18.9 = 1

Thanks for your help.

Yes. It is possible.

What operating system are you using?

What shell are you using?

What have you tried to solve this problem?

Please, give it a try.

Code:
perl -nle '++$r{int($_)}; END{for(sort keys %r){print "$_.0 - $_.9 = $r{$_}"}}' jiam912.input

Output:
Code:
15.0 - 15.9 = 4
16.0 - 16.9 = 3
17.0 - 17.9 = 2
18.0 - 18.9 = 1

With a bit of modification to yours:
Code:
awk '{a[int($1)]++}END{for(i in a) print i".0 - "i".9 =", a[i]}' input.file | sort -n

Please can you modify a little the code to use this input.

Code:
1 15.3

2 15.9

3 16.1
4 16.8
4 17.0
5 17.5
6 18.0
1 18.0
10 17.1

to get this output.
Code:
       15.0 - 15.9   16.0 - 16.9   17.0 - 17.9   18.0 - 18.9 
1           2             0             0             1
2           2             0             0             0
3           0             2             0             0
4           0             2             0             0
5           0             0             1             0
6           0             2             0             1
10          0             0             1             0

Please if is possible to use awk..

Hint: use a two-dimensional array to store the data, and two nested loops to print them.
