NEW QUESTION # 175
Task
In the Git repository cloned to ~/optimal-bedbug, edit the file hosts. Uncomment all the host entries in the group [webservers].
Finally, commit the change in file hosts using the commit message Enables missing hosts and push the commit to the remote.
Answer:
Explanation:
See the complete solution in Explanation.
Explanation:
Step 1: Connect to the correct Linux server.
The video specifies that this task must be completed on host lfcs00100.
From the candidate terminal, execute:
ssh lfcs00100
This establishes an SSH connection to the designated server.
All remaining commands must be executed on this host.
Step 2: Navigate to the existing Git repository.
Execute:
cd ~/optimal-bedbug
- cd changes the current directory.
- ~ refers to the current user's home directory.
- optimal-bedbug is the existing Git repository specified in the task.
Verify the current working directory:
pwd
List the repository contents:
ls -la
Check whether it is a valid Git repository:
git rev-parse --show-toplevel
The output should identify the root directory of optimal-bedbug.
The repository is already cloned. Therefore, there is no requirement to execute git init or git clone.
Step 3: Inspect the repository status.
Execute:
git status
This displays the current branch, modified files, staged changes, and working tree status.
Also execute:
git branch --show-current
This identifies the active branch.
Check the configured remote:
git remote -v
An example output might be:
origin git@example.com:training/optimal-bedbug.git (fetch)
origin git@example.com:training/optimal-bedbug.git (push)
The remote URL is illustrative. Use the remote already configured in the existing repository.
Do not modify unrelated repository configuration.
Step 4: Locate and inspect the hosts file.
Execute:
ls -l hosts
Display its complete contents:
cat hosts
The task requires editing the file named hosts in the repository.
Locate the section:
[webservers]
This is an inventory-style group heading.
The entries belonging to [webservers] appear below the heading and continue until the next group heading or the end of the file.
Step 5: Identify the commented host entries.
To display the [webservers] section, execute:
awk '
