i need to split it into

file1
ABCDEFGH|0987654321234567
ABCDEFGH|0987654321234523
ABCDEFGH|0987654321234556
ABCDEFGH|0987654321234545
ABCDEFGH|0987654321234556
ABCDEFGH|0987654321234545

file2
POIUYTRE|1234567890890678
POIUYTRE|1209867757352567
POIUYTRE|5463879088797131
POIUYTRE|5468980091344456
POIUYTRE|1234567890890678
POIUYTRE|5463879088797131
POIUYTRE|5468980091344456

by giving grep in the whole file like
grep 'ABCDEFGH' file name | wc -l will give the counts.

but for POIUYTRE it may differ then how can i split as above from the big file...


can anybody help.please....

maverix alredy give you the solution.

Did you check my earlier post??


The script I gave works fine for the type of file mentioned by you.
However, there's a catch in that script. If there's an empty line in the input file, a file by name ".txt" would be created. You can modify the script to address this or you can just delete it

Code:

sed -e "s/^\(.*\)|.*/\1/g" bigfile | sort -u > entries.txt
for file in $(entries.txt)
do 
  grep "${file}" bigfile > "${file}.txt"
done

entries.txt is creating with 2 redords as below.

ABCDEFGH
POIUYTRE

while running the for loop in seperate script entries.txt.txt is creating and it is empty. splitting is not happening.

My bad.
It should look like

Code:

sed -e "s/^\(.*\)|.*/\1/g" bigfile | sort -u > entries.txt
for file in $(<entries.txt)
do 
  grep "${file}" bigfile > "${file}.txt"
done
