My machine boots into command-line and then I run the following command to open a display with TWM window manager on it:$ xinit /usr/local/bin/twmOn TWM, this is how I run apps: I left-click anywhere on the black screen and a menu shows up. Then I select xterm and on xterm command-line, I run my app for example:$ operaThe problem is that for every app, I need a xterm to be opened first. I wonder if there is any other way by which I can open my apps without having to open xterm. Thanks.I ended up compiling/installing version 2.6.7 of fvwm which is also suggested here. It is a cool window manager with many features.
How to open apps on TWM window manager without using xterm
command line;window manager;twm
Define a menu in your .twmrc, like:Menu MyMenu{    Opera f.exec Opera}Then bind it to your left mouse button instead of the default one:Button1 = : root : f.menu MyMenuLook at TWM(1) to see how to configure TWM according to you needs. You may also want to see examples of configuration at xwinman.org.TWM lacks the feature of generating dynamic menus, so you'll need to define a menu for every set of apps you want to be accessible that way, or you can use the xdgmenumaker utility.
