How to use the command 'twm' (with examples)
The ’twm’ command is a window manager for the X Window system. It allows users to manage and control windows on the X server. It is a lightweight and highly configurable window manager.
Use case 1: Connect to the default X server
Code:
twm
Motivation: The motivation for this use case is to start the default X server and use ’twm’ as the window manager.
Explanation: By simply running the ’twm’ command without any arguments, it connects to the default X server and starts the ’twm’ window manager.
Example output:
Twm: twm: no image specified for iconPixmap resource
Twm: twm: no image specified for iconMask resource
Twm: twm: no image specified for iconWindow resource
TwmWindow.c: 544: AddIcon: assertion Botched
Use case 2: Connect to a specific X server
Code:
twm -display display
Motivation: The motivation for this use case is to connect to a specific X server instead of the default one.
Explanation: The ‘-display’ argument is used to specify the X server to connect to. By replacing ‘display’ with the appropriate display number or address, the ’twm’ command can connect to the desired X server.
Example output:
Twm: twm: no image specified for iconPixmap resource
Twm: twm: no image specified for iconMask resource
Twm: twm: no image specified for iconWindow resource
TwmWindow.c: 544: AddIcon: assertion Botched
Use case 3: Only manage the default screen
Code:
twm -s
Motivation: The motivation for this use case is to only manage the default screen when using ’twm’ as the window manager.
Explanation: The ‘-s’ argument is used to indicate that ’twm’ should only manage the default screen. This can be useful when there are multiple screens connected and the user wants to restrict ’twm’ to a specific screen.
Example output:
Twm: twm: no image specified for iconPixmap resource
Twm: twm: no image specified for iconMask resource
Twm: twm: no image specified for iconWindow resource
TwmWindow.c: 544: AddIcon: assertion Botched
Use case 4: Use a specific startup file
Code:
twm -f path/to/file
Motivation: The motivation for this use case is to specify a custom startup file for ’twm’ to use.
Explanation: The ‘-f’ argument is used to specify the path to a custom startup file. This file can contain configuration settings and commands to be executed when ’twm’ starts.
Example output:
Twm: twm: no image specified for iconPixmap resource
Twm: twm: no image specified for iconMask resource
Twm: twm: no image specified for iconWindow resource
TwmWindow.c: 544: AddIcon: assertion Botched
Use case 5: Enable verbose mode and print unexpected errors in X
Code:
twm -v
Motivation: The motivation for this use case is to enable verbose mode in ’twm’ and print out any unexpected errors that occur in the X server.
Explanation: The ‘-v’ argument is used to enable verbose mode, which allows ’twm’ to print out detailed information and error messages when interacting with the X server.
Example output:
Twm: twm: no image specified for iconPixmap resource
Twm: twm: no image specified for iconMask resource
Twm: twm: no image specified for iconWindow resource
TwmWindow.c: 544: AddIcon: assertion Botched
Conclusion:
The ’twm’ command provides various options for configuring the behavior of the ’twm’ window manager. It can be used to connect to different X servers, manage specific screens, use custom startup files, enable verbose mode, and more. Understanding these different use cases allows users to fully leverage the capabilities of ’twm’ as a window manager for the X Window system.
