Social Network in 30 days : Day 8 – Day 10

I haven’t had time to work on the site, LinksTeach.me, for sometime now. So what I’m going to do is delay development for 3 days to finish up a few other side projects and complete essential training.
I’ll startup backup on monday and plan to release an alpha version on Nov 11, 2013.

Awesome bash script:

find . -name main.go | xargs -L1 sed -ri "1s/^\/\/.*[^\.]$/&\./"`

The command finds all the files with the name main.go within the current directory.
After which, for each file it adds a dot to the end of the first line if it’s a comment and doesn’t need with a period.
Why is this useful?
`godoc` is a tool for creating documentation for Google Go files.
Example:
Source code for errors
Documentation for errors

`godoc` will use the first sentence as the description for a package. Since I didn’t end the first line with a period, then the entire comment on multiple lines becomes the description for the package.

So when run the awesome bash command above, it corrects the package comment each main.go like so.
