my ck.txt has (note there will be spaces after comma
jothi, m
john, n
joseph, o
jane,b
my data.txt has
jothi
john
joseph
johny
i have requirement like if first argument in the chk.txt file matches with argument in data.txt then write the second argument(m,n,o,etc by triing the spaces) of the chk.txt file to a file new.txt
i.e i need OUTPUT as new1.txt having
m
n
o
for this i USED
command
in batch file as
for /f %%i in (data.txt) do for /f " delims=, tokens=1,2 " %%j in (ck.txt) do if %%j==%%i set dat=%%k & set data=%dat: =% & echo %data% >> new1.txt
but in the file new1.txt
ECHO is on
ECHO is on
ECHO is on

Can anyone solve this

If I understood you right the following code should work.
(No guarantue if it is buggy) ;-)
I am WORKING with NT4, so I don't know how it behaves in other Windows VERSIONS.


@echo off
setlocal
cls
del new1.txt

for /f %%i in (data.txt) do for /f " delims=, tokens=1,2 " %%j in (ck.txt) do call :sub1 %%i %%j %%k

endlocal
goto :eof
:sub1
set data=%1
set ck=%2
set k=%3
if %data% EQU %ck% (echo %k% >>new1.txt)

:eof


hope it helps
ulihey it is working fine gurantee that it is bug FREE
