sum values based on ID
Hi,

I would like to be able to sum up the counts of a column by the ID of another column. Example (although the actual file I have has thousands of IDs):

Input file:

A1BG-AS1:001 3
A1BG-AS1:002 0
A1BG-AS1:003 2
A1CF:001 1038
A1CF:002 105
A1CF:003 115
A1CF:004 137


Desired output file:
A1BG-AS1 5
A1CF 1395


Thanks in advance!

Have a go with this:

Code:
awk '
    {
        split( $1, a, ":" );
        sum[a[1]] += $NF;
    }
    END {
        for( s in sum )
            print s, sum[s];
    }
'   input-file

Sums values in the last column, using the first column's name after truncating characters to the right of the colon.

close to ogama's solution but you could have used the field separator option of awk as follows:

Code:
awk -F'[: ]' '{ t[$1]+=$3 } END { for (i in t) print i, t[i] }' yourfile
