sudo apt-get update sudo apt-get install python3 python3-pip sudo pip install -r requirements.txt Step 4: Create a new file called “requirements.txt” in your home directory and paste the following content therein: python3 = “3.5” python3-pip = “1.7” requirements = [ ‘python’ ]
This was a simple technique to create a shell script on Linux using the default editor. Now let’s look at the next method.
Method 2: Using the Vim Text Editor Tool
