There are many ways to do this depending on the scripting language you are using; or if you are simply using a command line.

If you are simply using a command line, you can redirect to a file like this:

 command > output.txt

If you want to append to the same file, you can use:

 command >> output.txt

You can do this in a script so many, many ways; depending on your skill and tools; PERL, PHP, SED, AWK, etc etc.
