@Jotne: thank, this fullfil my initail requirement but when i have multiple lines then it doesn't work.

@zaxxon: requirement in this case is different than previous one. Now I 've values in columns. not in rows.

To be more precise. I've file of this formate:

Code:
;ip address    hostname     put-location      alt-put-location                tftpserver
192.168.1.1    r01-lab1-net /mnt/nas1/fgbu/   /opt/fgbu/devicebackup          192.168.1.254
192.168.1.2    r01-lab2-net /mnt/nas2/fgbu/   /opt/fgbu/backup                192.168.1.222

Now what i want is that:
Code:
read one line. 
set its values against different variable, 
do some operations using those variables (ip=192.168.1.1, hostname=r01-lab1-net etc)
move to next line
repeat above mentioned steps

so far, following code gives me each line.

Code:
sed 1d filename | while read  line
do
     echo line
done

but then i m unable to get different values from this line and assign them to variables. please let me know if this can work or there should be some other way. thanks.

AGGREGATE-IOS(1)                                              General Commands Manual                                             AGGREGATE-IOS(1)

NAME

       aggregate-ios - optimise a concatenated set of cisco/IOS prefix filters to help make them nice and short.

SYNOPSIS

       aggregate-ios <source_config >optimised_config

DESCRIPTION

       Takes  cisco IOS configuration on stdin, and optimises any prefix filters found using aggregate(1).  Optimised filters are produced on std-
       out.

OPTIONS

       None.

DIAGNOSTICS

       Any diagnostics produced by aggregate(1) are passed through on stderr.

EXAMPLES

       The following configuration fragment:

         ip prefix-list AS65530 description Foo, Inc
         ip prefix-list AS65530 permit 10.1.0.0/16
         ip prefix-list AS65530 permit 10.2.0.0/16
         ip prefix-list AS65530 permit 10.2.1.0/24
         ip prefix-list AS65530 permit 10.3.0.0/16
         ip prefix-list AS65531 description Bar.Com
         ip prefix-list AS65531 seq 5 permit 192.168.1.0/24
         ip prefix-list AS65531 seq 10 permit 192.168.2.0/24
         ip prefix-list AS65531 seq 15 permit 192.168.0.0/19

       is optimised as follows:

         ip prefix-list AS65530 permit 10.1.0.0/16 le 24
         ip prefix-list AS65530 permit 10.2.0.0/15 le 24
         ip prefix-list AS65531 permit 192.168.0.0/19 le 24
