Search a string and display its location on the entire string and make a text file

I want to search a small string in a large string and find the locations of the string. For this I used grep "string" -ob <file name where the large string is stored>. Now this gives me the locations of that string. Now how do I store these locations in a text file.

Did you consider redirecting the output?

After using grep -ob I am getting the location of the strings but I don't know how to store that in a text file.

Input and output redirection is a fundamental concept in all *nix OS, and even other proprietary OS have borrowed from them, so it'd be good to know their basics.
Use > filename to redirect some command's output to a file. Look into the man page of your shell for more insight.

Suppose I have given input a long string like SGHDRIAKGCJLFIFZKGCHXJFSGKCHVGZRUAJFAKGXLH
I want a text file storing the location of S like 1 24.
Suppose the string is stored as some text file like string.txt
Now I give the command
Code:
grep "S" -ob string.txt

Resultant output is
Code:
1 S
24 S

I want to store this output in a text file.
