Specs: Windows 2003 server
i want to store output of text file into a variable. So i can pass the whole file as parameter.

I am using windows 2003 server

The text files having multiple lines like
10.20.210.100 fish
10.20.210.101 rock

I was using
Set /P var=<file.txt

it reads only 1st line of the file. So if file having only 1 line then it’s ok .

I tried with FOR LOOP also but it assigning the last value to variable.

Need help

You can't achieve that anyway since an environment variable is a string ended by a CR/LF. So it is not possible to store into one variable a multi-lines text file.

Do you want eaxh line in a separate var or all the lines strung together?

Life is too important to be taken seriously.
