Sorry if this has been discussed, wasn't sure what to use to search for the particular question I had.

I'm installing sickrage and couchpotato and headphones, and will be doing multiple installs I made a small batch script just to install everything but what I don't know how to do is automatically make them auto start on boot. Since they all require a file to be created I do not know how to make this file auto create and populate what needs to be put into it.

    In bash scripting touch will create a new file and >> will append to the end of a file. Ex. touch newfile && echo This is a test >> newfile – karel Aug 23 '14 at 19:56
  • Can you give an example of what needs to be populated? If it's anything more than a couple of lines, I'd use a here document. – steeldriver Aug 23 '14 at 19:59
  • Would you mind sharing your bash script? – user319848 Aug 23 '14 at 21:53

As Karel suggested you can use touch to create the file and other commands to populate it:

Now Assuming you have created a file as follows: touch path/to/file we can use the following methods to populate it:

printf "Hello world\nNow a new line" >> path/to/file

or

echo "Hello world\nNow a new line " >> path/to/file

you can use >> to append to the file or > to replace everything in the file with new content.
