not sorting, search and to do arithmetic..

Hi thanks,

But my question is not like sorting.

I am explaining little detaily:

FIle 1:

123 678 345 hi 6798
452 789 256 bi 8746
145 689 124 ji 435
456 690 345 ki 789

File 2:
345
256
124

Expected Output:

The outfile should rearrange according to the fourth column of file1, matching with the first column of file2.

Like:

123 678 345 hi 6798
456 690 345 ki 789
452 789 256 bi 8746
145 689 124 ji 435

Then the column 5 should be added for 345 matching individuallly, 256 invidually, 124 individually.

Like:
the addition of 345 match 5th column is 6798+789 = 7587
the addition of 256 macth 5th column is 8746
the addition of 124 match 5th column is 435

Thanks in advance for your reply,
Vasanth

all you need is to sort numerically, you don't need Perl at all.

Code:
sort -rn -k4 file2

What's with the poll?

NAME
sieveshell - remotely manipulate sieve scripts SYNOPSIS
sieveshell [--user=user] [--authname=authname] [--realm=realm] [--exec=script] server[:port] sieveshell --help DESCRIPTION
sieveshell allows users to manipulate their scripts on a remote server. It works via MANAGESIEVE, a work in progress. The following commands are recognized: list list scripts on server. put <filename> upload script to server. get <name> [<filename>] get script. if no filename display to stdout delete <name> delete script. activate <name> activate script. deactivate deactivate all scripts. OPTIONS
-u user, --user=user The authorization name to request; by default, derived from the authentication credentials. -a authname, --authname=authname The user to use for authentication (defaults to current user). -r realm, --realm=realm The realm to attempt authentication in. -e script, --exec=script Instead of working interactively, run commands from script, and exit when done.
