The command "twm -s" is used to launch the "twm" window manager with the "s" flag. Here's what it does:
-
"twm" stands for "Tab Window Manager." It is a lightweight window manager for X Window System, which provides basic window management functionality such as titlebars, borders, and resizing.
-
The "-s" flag is an option specific to the "twm" command. In this context, it stands for "Synchronous." When used, it makes "twm" wait for requests from client applications before processing further events.
Launching "twm" with the "-s" flag can be useful for debugging purposes or when you need to troubleshoot issues related to the window manager. It allows you to interact with individual client applications and observe their behavior more closely by synchronizing their actions with "twm."
