 Dear Ladys and Gentleman,

during my work I noticed some strange behavior of the command "grep":

When I use grep according [1], I got some results but the recursive search is 
missing some results (see [2]):

[1]:
$ grep -irn "gpioPwm5"
examples/fsimx6sx/efusa9x_gpio_pins.c:36:gpio_config_t gpioPwm5 = {
examples/fsimx6sx/efusa9x_board.h:81:#define BOARD_GPIO_LED_BLINK_IMX           
   (&gpioPwm5)
examples/fsimx6sx/efusa9x_board.h:82:#define BOARD_GPIO_LED_CONFIG              
   (&gpioPwm5)
examples/fsimx6sx/efusa9x_gpio_pins.h:59:extern gpio_config_t gpioPwm5;

[2]:
$ grep -in "gpioPwm5" examples/fsimx6sx/gpio_pins.*
examples/fsimx6sx/gpio_pins.c:36:gpio_config_t gpioPwm5 = {
examples/fsimx6sx/gpio_pins.h:59:extern gpio_config_t gpioPwm5;


So the problem for me is that I can not find "gpioPwm5" in gpio_pins.c, when I 
perform 'grep -irn "gpioPwm5"'. Did I something wrong?
I attached the example to maybe support your research.

Please let me now if I can support you.
