Abstract: This paper provides an in-depth analysis of the technical differences between the "Run in Terminal" and "Run" options when double-clicking pycharm.sh in Ubuntu systems. By examining the underlying mechanisms of both launch methods, it explains how terminal execution opens a terminal window to display console output, while direct execution offers a cleaner user interface. The article also presents best practices for creating desktop shortcuts to optimize the PyCharm launch experience and discusses appropriate scenarios for selecting different modes in debugging contexts.
Analysis of PyCharm Launch Mechanisms in Ubuntu Systems
In the Ubuntu desktop environment, when users double-click the pycharm.sh script file, the system presents two distinct launch options: "Run in Terminal" and "Run". This phenomenon originates from the Linux desktop environment's handling mechanism for executable scripts, with both options representing different program execution approaches that substantially impact developers' workflows.
Technical Differences Between Launch Modes
From a technical implementation perspective, the "Run" option directly executes the pycharm.sh script, launching the PyCharm integrated development environment without displaying any terminal interface. This approach provides users with the cleanest launch experience, where the IDE interface appears directly, and all console output and error messages are redirected to system logs or the IDE's built-in console.
In contrast, the "Run in Terminal" option first opens a terminal window, then executes the pycharm.sh script within that terminal environment. The core advantage of this mode lies in its ability to display the program's complete console output in real-time, including startup logs, error messages, and debugging output. For instance, when executing Python code containing print("<T>"), the terminal window directly displays the escaped output content.
Best Practices for Creating Desktop Shortcuts
To avoid the need to select a launch mode each time PyCharm starts, creating desktop shortcuts is recommended. The specific operational workflow is as follows: First, navigate to the PyCharm extraction directory via terminal and execute the ./bin/pycharm.sh command to launch the IDE. Within the PyCharm interface, access the Tools menu and select the Create Desktop Entry... option. This operation generates a PyCharm launch entry in the system application menu, allowing users to directly click this entry to start the IDE without dealing with launch mode selection.
From a technical implementation perspective, desktop shortcuts actually create standard .desktop files that define the application's metadata and launch commands. This approach not only simplifies the launch process but also enables users to uniformly manage all development tools through the system application launcher.
Mode Selection Recommendations for Different Scenarios
For routine Python development work, direct execution mode is generally more appropriate. Most IDE functions, such as code editing, project management, and version control integration, do not require real-time viewing of console output. Direct execution mode provides a more focused development environment with reduced interface distractions.
However, in specific debugging scenarios, terminal execution mode demonstrates its unique value. When monitoring application startup processes, capturing specific error messages, or debugging command-line parameters, the ability to directly view console output becomes crucial. For example, when debugging code involving network requests or file operations, terminal output can provide real-time feedback.
It is noteworthy that even when selecting direct execution mode, PyCharm still offers comprehensive console tools. Users can view program output through the IDE's built-in "Run" and "Debug" tool windows, which provide enhanced features such as formatted output, error highlighting, and interactive debugging.
In-Depth Analysis of Underlying Technical Principles
The Ubuntu desktop environment's handling of .sh files is based on file association mechanisms. When users double-click script files, the system checks the file's execution permissions and MIME type, then determines how to proceed based on the desktop environment's configuration. Mainstream desktop environments like GNOME and KDE offer similar execution options, reflecting the Linux system's respect for user choice.
From a process management perspective, terminal execution mode actually creates a parent-child process relationship: the terminal process serves as the parent process, while the PyCharm process acts as the child process. This relationship ensures that when the terminal closes, the PyCharm process is also terminated, which aids resource management in certain scenarios. Direct execution mode, however, allows the PyCharm process to be directly managed by the desktop environment, offering better integration.

This distinction is crucial for understanding the technical implementations of different launch modes.
