To search for a string in output using grep in bash, you can use the following command:“`
command | grep “string”
Replace "command" with the command that produces the output you want to search, and "string" with the string you want to search for. For example, if you want to search for the word "error" in the output of a command that lists files in a directory, you can use the following command:
ls -l | grep
You can count the lines of output in bash using the following command: <command> | wc -l
Replace <command> with the command whose output you want to count the lines of. The | symbol is a pipe, which sends the output of the command to the wc command. The -l option tells wc to count the number of lines in the input. The result will be the number of lines of output from the original command.
Every WorkSpace is linked to the specific Amazon VPC and AWS Directory Service construct that was utilized to create it. Each AWS Directory Service construct (Simple AD, AD Connector, and Microsoft AD) needs two subnets, in different Availability Zones (AZs), to function. Once created, these subnets are permanently tied to a Directory Service construct and cannot be altered. Hence, it’s crucial to determine the appropriate subnet sizes prior to creating the Directory Services construct.
While creating the subnets, consider:
Amazon suggests establishing user groups, or personas, based on access type and user authentication requirements as part of your planning. These insights can assist in restricting access to specific applications or resources. User personas can guide segmentation and restriction of access using AWS Directory Service, network access control lists, routing tables, and VPC security groups.
Each AWS Directory Service construct employs two subnets and applies uniform settings to all WorkSpaces launched from that construct. For instance, a security group attached to an AD Connector could dictate whether Multi-Factor Authentication (MFA) is necessary or whether an end-user can have local admin access on their WorkSpace.
Remember that each AD Connector links to your existing Enterprise Microsoft AD. To specify an Organizational Unit (OU) and leverage this capability, your Directory Service must be constructed with your user personas in mind.
Amazon WorkSpaces employs two protocols: PCoIP and WorkSpaces Streaming Protocol (WSP). The selection of the protocol is influenced by various factors such as the devices from which users will access their WorkSpaces, the operating system of your WorkSpaces, the network conditions that users will encounter, and the need for bidirectional video support.
PCoIP should be utilized under the following circumstances:
WSP is recommended in these situations:
It’s important to note that a directory can contain a combination of PCoIP and WSP WorkSpaces. A user can have both a PCoIP and a WSP WorkSpace, provided the two WorkSpaces are in separate directories. The same user cannot have a PCoIP and a WSP WorkSpace in the same directory. Further information about creating multiple WorkSpaces for a user can be found in the “Create multiple WorkSpaces for a user” section.
WorkSpaces migration feature can be used to switch a WorkSpace between the two protocols, but this requires a rebuild of the WorkSpace. For more details, refer to the “Migrate a WorkSpace” section.
If your WorkSpace was created with PCoIP bundles, you can change the streaming protocol to switch between the two protocols without needing a rebuild, while keeping the root volume intact. More information can be found in the “Modify protocols” section.
For optimal video conferencing experience, the use of Power or PowerPro bundles is recommended.

To use CloudFormation to create an Amazon WorkSpaces instance, you can follow these steps:1. Create a CloudFormation template: You can create a CloudFormation template in JSON or YAML format. The template should include the necessary resources to create an Amazon WorkSpaces instance, such as the WorkSpaces directory, WorkSpaces subnet, and WorkSpaces bundle.2. Define the WorkSpaces directory: In the CloudFormation template, you need to define the WorkSpaces directory. This includes specifying the directory name,
Resources:
MyWorkspace:
Type: AWS::WorkSpaces::Workspace
Properties:
BundleId: bundle-id
DirectoryId: directory-id
UserName: user-name
RootVolumeEncryptionEnabled: true/false
UserVolumeEncryptionEnabled: true
To list all instances in the AWS CLI, you can use the aws ec2 describe-instances command. Here’s an example:
aws ec2 describe-instances
This will return a list of all instances in your default region, along with their details such as instance ID, instance type, status, and more.
If you want to filter the results based on certain criteria, you can use various filters with the --filters option. For example, if you only want to list instances with a specific tag, you can use the following command:aws ec2 describe-instances --filters "Name=tag:Name,Values=my-instance"
This will only return instances that have a tag named “Name” with a value of “my-instance”. You can modify the filter to suit your needs.
Note that you’ll need to have the appropriate permissions to run this command. If you encounter any issues, check your IAM user’s permissions or consult with your AWS administrator.
To only get the output of just instance IDs in the AWS CLI, you can use the --query parameter with a JMESPath expression. Here’s an example command:
aws ec2 describe-instances --query 'Reservations[].Instances[].InstanceId' --output text
This command uses a JMESPath expression to query the InstanceId attribute of each instance and return only that value. The --output parameter is set to text to ensure that the output is in plain text format.
The result will be a list of instance IDs.
Remember that you can run was CLI commands at the bottom of the console by enabling CloudShell.
To install Terraform on a Mac, you can follow these steps:
Option 1
Use Brew
brew tap hashicorp/tap
brew install hashicorp/tap/terraformOption 2
Download the Terraform package: Go to the Terraform downloads page at https://www.terraform.io/downloads.html and download the package for your Mac. You can choose between a 32-bit or 64-bit version.
Unzip the package: Once you download the package, unzip it to a directory of your choice. You can use the following command in the terminal:
unzip terraform__darwin_amd64.zipReplace with the version number of the package you downloaded.
Move the binary to a directory in your PATH: Once you unzip the package, move the Terraform binary to a directory in your PATH. You can use the following command in the terminal:
sudo mv terraform /usr/local/bin/This will move the binary to the /usr/local/bin directory, which is usually included in the PATH environment variable.
Verify the installation: To verify that Terraform is installed correctly, open a new terminal window and run the following command:
terraform versionThis should display the version number of the Terraform binary you installed.
That’s it! You have now installed Terraform on your Mac and are ready to use it to manage your infrastructure.
