Hi Guru,

Thank you for your reply.

Why is it not working agaisnt following data set. Can you please explain a bit on how is the sub function working in awk.

Code:

SUSPREL,ICP_MED_DEL_SEM_20130309_1038,80,25.60
REL,ICP_MED_DEL_SEM_20130309_1038,24290,18543.38
ERROR_ALLRATE_DSC_DLK,ICP_dsc_dlk_MED_DEL_SEM_20130309_1038,3,10.10
SUSPREL,ICP_MED_DEL_SEM_20130309_1039,80,25.60
REL,ICP_MED_DEL_SEM_20130309_1039,24290,18543.38
ERROR_ALLRATE_DSC_DLK,ICP_dsc_dlk_MED_DEL_SEM_20130309_1039,3,10.10

Another point is that the data between ICP and MED can be of any leth.

Hi Rudic,

Thank you for your reply. However, the output that you have showed is not what I am expecting

Let me explain a bit more. If you check the value in column 2, you will see that the values are like FILE1_MYFILE_20130309_1038, FILE1_MYFILE_20130309_1038, FILE1_dsc_dlk_MYFILE_20130309_1038. These are actually from the same group. The only difference is that there are some additional values between FILE1 and MYFILE. Hence I want to add all the corresponsing column 3 values. If this is not possible in awk, I was thinking if I remove the values between FILE1 and MYFILE first using awk and then add the values in column 3. What is your input on that and how do I remove those values?

Thanks and Regards

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.
