How do I close a file in git editor?
After writing commit message:
Esc
write :wq (which means “write and quit“) or :wq!
Enter to close the unix file.

Any file may be opened in any editor. So run
“ps -ax|grep vim”
to check which file is opened in which editor. And then run kill id-of-editor . For e.g.
“kill 12345” Thats all
———————————
The command ps -ax displays yours as well as other users’ processes

grep matches lines which match a regular expression. In this case, the regular expression is …
==================================
Right angle bracket (>) redirects the output to a file called catch. If the file exists, it will first be truncated (emptied), otherwise it will be created.
———————————————————-

iOS > Tic Tac Toe Game

Posted by Franz

Learn how to create a two person game for iPhone/iPad with three different modes.

The first mode is where you can play against an opposing player by passing the phone or iPad between two players to take turns. The second mode is where you can challenge your phone and see who comes out top and the third mode uses the multipeer connectivity framework to pit two players against each other, each running the application on their own device.
