Useful Tips for Developers who used Mac

These tips can be used in OSX 10.9

1. Open the finder window at current terminal location.

    open .

2. Open a terminal at a finder window

    you have to create your own shortcut for this. follow below steps to do that
  • Go to System Preferences -> Keyboard -> Shortcuts -> Services
  • Tick the checkbox at New Terminal at Folder
  • Click the none text(light grey) in right side of New Terminal at Folder checkbox
  • Press your own shortcut key combination
I experienced this shortcut is not available until you access this feature via context menu.
  • Right click on a finder window -> Services -> New Terminal at Folder 
and one thing I noticed is until you restart the machine, It takes some time to open the terminal after you press the shortcut keys.

3. Create new empty text file using terminal

    touch <textfile_name>.txt

4. Open a text file using terminal, Write something to it and Exit from it

    vi <textfile_name>
  • if you want to write something on file, press i
  • if you write nothing on file and wants to exit, press q
  • if you write something on file and wants to save it and quit, press wq
  • if you write something on file and wants to quit without saving it, press q!

5. Search inside files using grep command

    grep "text to search" -R .
   Here R option used to search recursively. dot(.) is used to say that search from current folder

6. View hidden files using terminal

    ls -al
   a is used to say show all files l parameter is used to say long list(descriptive manner) the files

I referred below articles to write this.
