do u want ur file in two parts from the middle??

ur req "1-8 character." is not clear...
Pl explain..

as i said above after spliting process i need 2 seperate files file1 and file2

Code:

for i in $(cut -d'|' -f 1 test | sort | uniq); do grep ^$i test > ${i}.txt; done

if ur file is same as u said..
thn use this..
split -l 4 file.txt

now there 'll be two files with names xaa and xab with the contents u want

Anchal.

For testing purpose i have given only 4 records,

actually it may be in lacs...what is the method in that case??

split -l is the best options, do a man on split and read the -l option.



The following options are supported:

-linecount | -l linecount
Number of lines in each piece. Defaults to 1000 lines.

1) wc filename ( one you know the total # of lines you can decide on splitting them in either 2 or 2 or n number of smaller files.

For example if your file has 100000 lines

split -l 50000 filename will give you two file xaa and xab with 50000 lines each.

if you do

split -l 20000 filename it will give you xaa, xab , xac, xad, xae files with exactly 20000 lines in each file.

I hope this helps.
