Breaking the sum of a column when specific pattern is found
Hi
Am trying to sum up a file
Code:
# cat /Out
maths 2 0.0
english 2091 0.2
history -1 0.0
physics 18 0.0
--------------------------------------
maths 2 0.0

physics 18 0.0
-------------------------------------
maths 2 0.0
english 2091 0.2
history -1 0.0
physics 18 0.0
Am trying to sum up only the second column of the file
I need to sum up like, When "-------------" is met the values that had sum up so far should be stored in another variable and then a new sum from zero has to be proceeded until again "-------------------" is met and store the value in another new variable
I reached till
Code:
we=`awk '{print $2}' /Out |grep '[0-9]'|awk '{sum+=$1} END {print sum}'`
But this gives the sum of entire column..
Please help..

I have a file (let say file B) like this:
File B:
A1 3 5
A1 7 9
A2 2 5
A3 1 3
The first column defines a filename and the other two define a range in that specific file. In the same directory, I have also three more files (File A1, A2 and A3). Here is 10 sample lines... (3 Replies)

sum
sum(n) Cyclic Redundancy Checks sum(n)
__________________________________________________________________________________________________________________________________________________NAME
sum - Calculate a sum(1) compatible checksum
SYNOPSIS
package require Tcl 8.2
package require sum ?1.1.0?
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
_________________________________________________________________DESCRIPTION
This package provides a Tcl-only implementation of the sum(1) command which calculates a 16 bit checksum value from the input data. The
BSD sum algorithm is used by default but the SysV algorithm is also available.
COMMANDS
::crc::sum ?-bsd | -sysv? ?-format fmt? ?-chunksize size? [ -filename file | -channel chan | string ]
The command takes string data or a file name or a channel and returns a checksum value calculated using the sum(1) algorithm. The
result is formatted using the format(n) specifier provided or as an unsigned integer (%u) by default.
OPTIONS -sysv The SysV algorithm is fairly naive. The byte values are summed and any overflow is discarded. The lowest 16 bits are returned as the
checksum. Input with the same content but different ordering will give the same result.
-bsd This algorithm is similar to the SysV version but includes a bit rotation step which provides a dependency on the order of the data
values.
-filename name
Return a checksum for the file contents instead of for parameter data.
-channel chan
Return a checksum for the contents of the specified channel. The channel must be open for reading and should be configured for
binary translation. The channel will no be closed on completion.
-chunksize size
Set the block size used when reading data from either files or channels. This value defaults to 4096.
-format string
Return the checksum using an alternative format template.
EXAMPLES
% crc::sum "Hello, World!"
37287
% crc::sum -format 0x%X "Hello, World!"
0x91A7
% crc::sum -file sum.tcl
13392
