    Choose your software packages. You will be presented with a long list of packages that will seem daunting in their scope if you are new to Cygwin. If you are new to Cygwin, stick with the default packages and click "Next." Wait for the loading bar to complete, which may take a few minutes.[1]

    Use Cygwin as you would UNIX. It might require a bit of customization. For example, adding your user name to "/etc/password." Make sure you allow it to put an icon on your desktop during setup. When you double-click that icon, it will open up a shell window.

Using Cygwin: The Basics

  1. Picture 9 of How to Use Cygwin
    Find a file. Some of the most basic commands you can use in Cygwin are the search and comparison tools. To find a file you can input the following command: $ find . -name EXAMPLE. This will show you all of your files with that name, however, it is case sensitive.[2]
  2. Picture 10 of How to Use Cygwin
    Find a keyword within a file. If you would like to find certain text within a file, you need to incorporate the "grep" command. Thus, to find all instances of "EXAMPLE" you would need to input $ grep 'EXAMPLE' EXAMPLE.txt. This will provide you with all of the instances of the text "EXAMPLE" within the EXAMPLE.txt file. However, this particular command is case sensitive. To find all instances of "EXAMPLE" regardless of case, continue to the next step.
  3. Picture 11 of How to Use Cygwin
    Find text regardless of case. To find text regardless of text, simply add -i after the grep command. It should look something like this: $ grep -i 'EXAMPLE' EXAMPLE.txt.
  4. Picture 12 of How to Use Cygwin
    Compare two files. If you would like to compare two files, you can easily do so by entering the diff command. Simply input the command followed by the names of the two files you wish to compare: diff EXAMPLE.txt PRACTICE.txt. This will then present you with the two files, one after another.[3]
