subtotal columns
Hello

I have a file that has two (or more) different types of records I want to total. How would I do this using awk?

The file may contain several dozen records. The records are sorted on the database column - what I want to do is get the amount of space that each table has in that database and, add that amount to a variable. When the database changes, I want to print out that subtotal, reset the variable to zero and process the rest of the file.

I've seen examples where awk will total the ENTIRE column but, I need to create subtotals for each database when it changes (2,3,4,maybe more). I'm thinking awk would be the most effective way to go with this; is there something else that I could use? Any help would be greatly appreciated.

Thanks

colrm

COLRM(1)						    BSD General Commands Manual 						  COLRM(1)

NAME

     colrm -- remove columns from a file

SYNOPSIS

     colrm [start [stop]]

DESCRIPTION

     The colrm utility removes selected columns from the lines of a file.  A column is defined as a single character in a line.  Input is read
     from the standard input.  Output is written to the standard output.

     If only the start column is specified, columns numbered less than the start column will be written.  If both start and stop columns are spec-
     ified, columns numbered less than the start column or greater than the stop column will be written.  Column numbering starts with one, not
     zero.

     Tab characters increment the column count to the next multiple of eight.  Backspace characters decrement the column count by one.

ENVIRONMENT

     The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).

EXIT STATUS

     The colrm utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     awk(1), column(1), cut(1), paste(1)

HISTORY

     The colrm command appeared in 3.0BSD.
