String Replacement

At xFusionCorp Industries, the Stratos Datacenter houses a jump host server that stores template XML files essential for the Nautilus application. Prior to their use, these files need to be populated with valid data. As part of regular maintenance, the system administration team utilizes various string and file manipulation commands to prepare these templates. Your task is to substitute all occurrences of the string Text with Echo-Location within the XML file located at /root/nautilus.xml on the jump host server. Solution Step 1: Connect to the Jump Host Server ssh thor@jump-host # Password: mjolnir123 Step 2: Switch to root sudo su - # Password: mjolnir123 Step 3: Verify the file exists and check its content # Check if file exists ls -la /root/nautilus.xml # View the file content (optional) cat /root/nautilus.xml Step 4: Substitute all occurrences of "Text" with "Echo-Location" Method 1: Using sed (Recommended) sed -i 's/Text/Echo-Location/g' /root/nautilus.xml Command breakdown: sed : Stream editor for filtering and transforming text -i : Edit files in-place (without backup) s/Text/Echo-Location/g : Substitute all occurrences s : Substitute command Text : Pattern to search for Echo-Location : Replacement string g : Global (replace all occurrences, not just the first) Method 2: Using sed with backup (Safer) sed -i .bak 's/Text/Echo-Location/g' /root/nautilus.xml This creates a backup file nautilus.xml.bak before making changes. Step 5: Verify the changes # View the modified file cat /root/nautilus.xml # Check for any remaining "Text" strings grep -n "Text" /root/nautilus.xml # Check for "Echo-Location" strings grep -n "Echo-Location" /root/nautilus.xml # Count occurrences replaced grep -o "Echo-Location" /root/nautilus.xml | wc -l Complete One-Line Commands From jump host directly (as root): sed -i 's/Text/Echo-Location/g' /root/nautilus.xml && echo "✓ Substitution complete" && grep -c "Echo-Location" /root/nautilus.xml From jump host with sudo: sudo sed -i 's/Text
