Need help on creating a batch file.

[justhink]

Hi All,

I have created following batch file which will read value from a text file and set a variable. But somehow it's not working, to debug, i have added several pause on the file, and found that it's automatically closing after executing FOR statement.

But if i execute the for statement on direct command line it's working and also it's setting the variable.

Please help me to fix this

@echo off
pause
FOR /F "tokens=2" %a in (C:\chk.txt) do set _port=%a
pause
::set _reg=open
if "%_port%"  == "open" ( echo : True : 
pause
exit)
echo : False :
pause
exit

Content of the chk.txt is:

25/tcp open  smtp

After executing FOR statement directly on command prompt.

C:\>FOR /F "tokens=2" %a in (C:\chk.txt) do set _port=%a

C:\>set _port=open

C:\>echo %_port%
open

C:\>

Solved!!

Solved!!

...by adding a % sign to have two in front of variables:

• %a on command line
  
• %%a in batch script

Just to clear the sense of my post, the plot WITHOUT it:

1. you have a problem
   
2. you solved it, and say so WITHOUT telling HOW
   
3. noone else will ever be able to benefit from the reported experience
   

and the plot WITH it:

1. you have a problem
   
2. you solved it
   
3. HOW it was solved is posted
   
4. someone else with your same problem may benefit from the reported experience

It appears that they received a response from elsewhere first but couldn't be bothered to update us!

I am extremely sorry for doing so, I was i hurry to solve the problem, and after it solved, i was busy with another problem.

So sorry again, and in future i will not do the same..
