Full Discussion: .bashrc in Ubuntu 14.04
Operating Systems Linux Fedora .bashrc in Ubuntu 14.04 Post 302958411 by bakunin on Thursday 22nd of October 2015 01:00:45 AM

@MadeInGermany: good question! My answer is a firm: that depends. ;-))

As i said earlier, .profile is executed once for every login(-shell), .rc-files (depending on the login shell ~/.kshrc or ~/.bashrc or even something else) are executed for every new shell. Whatever you want to execute every time you log in goes to the profile, whatever you want executed for every new shell goes to the rc-file.

True. In some environments i put a sort-of "reentrancy-protection" into my .kshrc to prevent that:

Code:
if [ "$NEVER_USE_THIS_VAR" = "" ] ; then
     PATH="$PATH:/dir/to/add"
     ....
     typeset -x NEVER_USE_THIS_VAR="Kilroy was here."
fi

But i have to say that nested shells happen rarely at my workplace. My typical environment consists of an X-server, mwm on top and many xterms. The login session starts the window manager via exec, so the shells in the xterms are each first-level shells because the login-process was replaced by the mwm.

I do not use "desktops" like KDE, GNOME or whatever they are called if i can avoid it, so i can say nothing about how these work.

glutIgnoreKeyRepeat(3GLUT)					       GLUT						glutIgnoreKeyRepeat(3GLUT)

NAME

       glutIgnoreKeyRepeat - determines if auto repeat keystrokes are reported to the current window

SYNTAX

       #include <GLUT/glut.h>

       void glutIgnoreKeyRepeat(int ignore);

ARGUMENTS

       ignore	 Non-zero  indicates auto repeat keystrokes should not be reported by the keyboard and special callbacks; zero indicates that auto
		 repeat keystrokes will be reported.

DESCRIPTION

       glutIgnoreKeyRepeat determines if auto repeat keystrokes are reported to the current window.  The ignore auto repeat state of a window  can
       be queried with glutDeviceGet(GLUT_DEVICE_IGNORE_KEY_REPEAT).

       Ignoring  auto  repeated  keystrokes  is generally done in conjunction with using the glutKeyboardUpFunc and glutSpecialUpFunc callbacks to
       repeat key releases.  If you do not ignore auto repeated keystrokes, your GLUT application will	experience  repeated  release/press  call-
       backs.  Games using the keyboard will typically want to ignore key repeat.

GLUT IMPLEMENTATION NOTES FOR X11
       X11  sends  KeyPress  events repeatedly when the window system's global auto repeat is enabled.	glutIgnoreKeyRepeat can prevent these auto
       repeated keystrokes from being reported as keyboard or special callbacks, but there is still some minimal overhead by the X server to  con-
       tinually  stream  KeyPress events to the GLUT application.  The glutSetKeyRepeat routine can be used to actually disable the global sending
       of auto repeated KeyPress events.  Note that glutSetKeyRepeat affects the global window system auto repeat state so other applications will
       not auto repeat if you disable auto repeat globally through glutSetKeyRepeat.
