You should mention that if someone uses this he needs FOSUserBundle too.

If you press ctrl+R and then start typing you can search in your command history.

I use this function:

function findr
{
    grep -RnisI $1 .;
}

Use it like this:

$> findr "Find me"

Your first example is not exactly right. The second {username} is not username but the group's name. Note that there are groups with every user's name but you change it to something like www if you'd like to allow your webserver to handle the files.

sudo chown -R {username}:{group} {target_file}

chown

Or you can use tig which is capable of doing a bunch of more things too.
