Question

I am trying to call a function present in saur.exe using bat.
It looks something like this:

saur.exe readName

When i execute it, it returns a string “Saurabh”.

Now that I want to store “saurabh” in a variable called name.

So I am doing :

set name = saur.exe readName
echo .%name%

In this case, it doesnot execute.
It gives blank in front of echo command.

Answer 1

Some SET command documentation will show that you can only assign strings to environment variables (http://www.computerhope.com/sethlp.htm).

In your example above, you have actually set an environment variable called:

"name "

Yet you are echoing the variable:

"name"

The best solution I can find is to do something similar to

saur.exe readName>tempFile
SET /p variableName=<tempFile
ECHO %variableName%

Hopefully this helps 🙂
