Xshell Highlight Sets are a powerful productivity feature designed to provide instant visual cues for specific text strings, error codes, or log patterns appearing in your terminal. By automatically color-coding or formatting keywords as they are output, you can spot critical information without manually scanning through lines of code or logs. What are Highlight Sets?
Highlight Sets allow you to define groups of keywords or regular expressions that Xshell will monitor in real-time. When a match is found, Xshell applies your chosen font style or color.
Real-time Emphasis: Strings are highlighted as soon as they appear in the terminal window.
Granular Control: You can apply different sets to different sessions based on your specific tasks, such as database management versus web server logs.
RegEx Support: Uses the Perl-compatible DEELX engine for advanced pattern matching (e.g., highlighting specific IP address ranges or timestamps). How to Create and Manage Highlight Sets
You can access these settings directly through the Official Xshell User Guide or by following these steps within the application:
Open the Manager: Go to the Tools menu and select Terminal Highlight Sets.
Create a New Set: Click New and provide a descriptive name (e.g., "Error-Logger" or "Success-Cues"). Add Keywords: Select your new set and click Add. Keyword: Enter the specific text or a Regular Expression.
Case Sensitive: Check this if "Error" should be highlighted but "error" should not.
View Style: Choose your foreground/background colors or bolding options.
Apply to Session: In the Highlight Sets dialog box, select your set and click Set to Current to apply it immediately to your active session. Pro-Tips for Maximum Productivity
Use Exact Matches: For keywords that might be part of other words, use word boundaries in regex. For example, use \bDOWN\b to highlight the word "DOWN" only, avoiding accidental highlights in words like "countdown".
Persistent Highlighting: You can assign a specific Highlight Set to a session permanently by navigating to the Session Properties > Appearance category.
Color Optimization: Use the Xshell-ColorScheme repository on GitHub to find community-shared themes that pair well with custom highlight sets for better visibility.
Term Color Option: To change text color without overriding the background (keeping your original theme intact), ensure you select the Term Color option in the Keyword dialog box. Manual - Xshell - NetSarang Computer

Xshell Highlight Sets allow you to create visual cues by automatically colorizing specific keywords or patterns in the terminal output. This is particularly useful for spotting critical logs, errors, or IP addresses that might otherwise get lost in a wall of text. Key Setup and Usage
Creating a Set: Go to the Tools menu and select Terminal Highlight Sets. Click New to name and create a set.
Adding Keywords: In the Highlight Sets dialog, click Add to enter a keyword.
Regular Expressions: Check the Regular Expression box for complex patterns like IPs or timestamps. Xshell uses the Perl-compatible DEELX engine.
Case Sensitivity: Use the "Case Sensitive" toggle to distinguish between "Error" and "error". Xshell Highlight Sets are a powerful productivity feature
Styling: You can change the text color, background, or font style (e.g., bold) for each keyword.
Applying to Sessions: Once a set is created, you must apply it to your session via the Highlight Sets Dialog or the session properties to see the changes in real-time. Helpful Highlight Examples
Effective highlight sets often include patterns for immediate troubleshooting:
Errors and Warnings: Highlight "ERROR", "CRITICAL", or "FAIL" in red; "WARNING" in yellow.
Connectivity Status: Use green for "UP", "CONNECTED", or "SUCCESS", and red for "DOWN" or "DISCONNECTED".
Network Data: Create regex patterns for IPv4/IPv6 addresses, MAC addresses, or URLs to make them stand out in command outputs like ifconfig or nmap.
Specific Identifiers: Highlight phone numbers, emails, or user IDs relevant to your specific tasks. Optimization Tips Manual - Xshell - NetSarang Computer
Click New and give your set a name (e.g., "Production Log Highlighting").
Don't just highlight one word. Use regex to highlight patterns:
\b\d4-\d2-\d2\b (Dates)\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]2,\b (Email addresses)[0-9]+% (Percentages)By default, Xshell might ask you which Highlight Set to use when you open a new tab, or you can set a default:
.ini file from:
%APPDATA%\NetSarang\Xshell\HighlightSets\
