grep -q might not work with all grep versions. What is your OS?
Code:
tail -f $UMPath/data/nirvana.log | while read line
do
done
Several problems with that.
The pipe forces the while-do-done block into a sub shell.
While the return should work an exit can produces different results, dependent on the shell. BTW what shell and OS do you use?
Your main problem: changes on variables are not copied back to the main shell.
Then, if the sub shell terminates, it sends a SIGPIPE to the tail -f that hopefully terminates.
The following eliminates some problems
Code:
# Watch the log file for the initialization string
getline()
{
# use the portable printf in favor of echo -e
printf "\nNow watching nirvana log for the Started Nirvana Realm string"
# tail -f will hopefully terminate
tail -f $UMPath/data/nirvana.log |
# the pipe forces the while-do-done into a sub shell:
# variables are not returned but a return value should work
while read line
do
case "$line" in
*"Realm Server Startup sequence completed"*)
printf "\nFound: %s\n\n" "$line"
return 0
;;
*"Server shutdown"*)
printf "\nFound: %\n\n" "$line"
return 1
;;
esac
done
}
# act on the return value
if getline
then
echo "UM is now up and running"
else
echo "UM failed to start. Please check"
rval=1
fi
exit $rval

glutignorekeyrepeat
glutIgnoreKeyRepeat(3GLUT) GLUT glutIgnoreKeyRepeat(3GLUT)NAME
glutIgnoreKeyRepeat - determines if auto repeat keystrokes are reported to the current window
SYNTAX
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.
