How do I create a launch file?
The tutorials says ""Now let's create a launch file called turtlemimic.launch and paste the following: "" How do I create a launch file?
In the package, create a folder by the name launch and create a filename.launch file.
How do I create this file?
write the launch file in gedit and save it with a .launch extension ! was that your issue ?
If this is how you do it then how do I use gedit, I don't see gedit on the dashboard.

Install gedit , gedit is editor, you can use any editor which you like.
sudo apt-get install gedit
just create a empty document and rename it with .launch extension and write your content.

I saved it to home/pc/catkin_ws/src/beginner_tutorials/launch but it said I didnt have permission so I sudo it and it saved then but its not an xml file its a plain text file,

the last line was without using gedit. launch file is a plan text file with xml syntax. What is the error ur getting while using launch file ?

If it's not in the launcher just type gedit in a terminal....

Use any editor - emacs/vim/nano from the terminal or gedit, copy and paste the content from the tutorial and save the file as turtlemimic.launch
