• LIRC setup in Raspberry PI Raspbian Jessie.
• Install LIRC packages with, sudo apt-get install lirc.
• Set up pin connection in /etc/modules. Please remember to put / in front of etc, so it is /etc/modules and not etc/modules.

lirc_dev
lirc_rpi gpio_in_pin=23 gpio_out_pin=22

• Now I need a way to modify configuration file from terminal.
• From this link, http://serverfault.com/questions/39303/how-to-add-line-to-system-configuration-file-with-sudo the example terminal command is this, echo "nameserver 192.168.1.6" | sudo tee -a /etc/resolv.conf.
• Trying my own example command.

echo "test test" | sudo tee -a /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf

• From the example code above I have "test" and then after I applied the code it becomes "testtest test". So I need to apply line break manually.

echo "\ntest test" | sudo tee -a /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf

• After I execute code above my .conf file is like this.

testtest test
\ntest test

• Apparently \n is not registered as an escape character.
• I checked other example command to add line into configuration file, sudo /bin/sh -c 'echo "nameserver 192.168.1.6" >> /etc/resolv.conf'.
• I modify it into my need.

sudo /bin/sh -c 'echo "test test test" >> /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf'

• Testing other command aside from using echo, printf.
• From this discussion, http://stackoverflow.com/questions/11193466/echo-without-newline-in-a-shell-script. I know that echo is good for simple code. However, printf can be used for more stability.

sudo /bin/sh -c 'printf "test test printf" >> /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf'

• Adding line break before adding the modified codes.

sudo /bin/sh -c 'printf "\n\ntest test printf" >> /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf'

• Apparently printf is capable to understand \n which is nice. However, as you can see from the code above I need to add 2 \n to get 1 line break.
• I guess the 1st line break is neglected?
• So I need to add these into /etc/modules.

lirc_dev
lirc_rpi gpio_in_pin=23 gpio_out_pin=22

• Testing codes.

sudo /bin/sh -c 'printf "\n\nlirc_dev\nlirc_rpi gpio_in_pin=23 gpio_out_pin=22" >> /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/config-test.conf'

• The bash codes above is perfect. So now I need to adjust it into /etc/modules.

sudo /bin/sh -c 'printf "\n\nlirc_dev\nlirc_rpi gpio_in_pin=23 gpio_out_pin=22" >> /etc/modules'

• /etc/modules is used to list an optional kernel that should be loaded.
• Testing to write configuration file from shell script.

• Clean up the code.

sudo /bin/sh -c 'printf "########################################################\n# /etc/lirc/hardware.conf\n#\n# Arguments which will be used when launching lircd\nLIRCD_ARGS=\"--uinput\"\n\n# Do not start lircmd even if there seems to be a good config file\n# START_LIRCMD=false\n\n# Do not start irexec, even if a good config file seems to exist.\n# START_IREXEC=false\n\n# Try to load appropriate kernel modules\nLOAD_MODULES=true\n\n# Run \"lircd --driver=help\" for a list of supported drivers.\nDRIVER=\"default\"\n# usually /dev/lirc0 is the correct setting for systems using udev\nDEVICE=\"/dev/lirc0\"\nMODULES=\"lirc_rpi\"\n\n# Default configuration files for your hardware if any\nLIRCD_CONF=\"\"\nLIRCMD_CONF=\"\"\n########################################################" >> /home/notalentgeek/Downloads/project-commitment/pc-ut-bachelor-thesis-2016/deliverable-programming/test-bash-add-config-file-1/lircd.conf'

• Change the target into /etc/lirc/hardware.conf. But we need first to delete the original LIRC configuration file.

sudo rm /etc/lirc/hardware.conf
sudo /bin/sh -c 'printf "########################################################\n# /etc/lirc/hardware.conf\n#\n# Arguments which will be used when launching lircd\nLIRCD_ARGS=\"--uinput\"\n\n# Do not start lircmd even if there seems to be a good config file\n# START_LIRCMD=false\n\n# Do not start irexec, even if a good config file seems to exist.\n# START_IREXEC=false\n\n# Try to load appropriate kernel modules\nLOAD_MODULES=true\n\n# Run \"lircd --driver=help\" for a list of supported drivers.\nDRIVER=\"default\"\n# usually /dev/lirc0 is the correct setting for systems using udev\nDEVICE=\"/dev/lirc0\"\nMODULES=\"lirc_rpi\"\n\n# Default configuration files for your hardware if any\nLIRCD_CONF=\"\"\nLIRCMD_CONF=\"\"\n########################################################" >> /etc/lirc/hardware.conf'

• After this I need to restart the LIRC service.

sudo /etc/init.d/lirc stop
sudo /etc/init.d/lirc start

• There is this safety measure, add these lines into /boot/config.txt.

dtoverlay=lirc-rpi,gpio_in_pin=23,gpio_out_pin=22

• Shell script.

sudo /bin/sh -c 'printf "dtoverlay=lirc-rpi,gpio_in_pin=23,gpio_out_pin=22" >> /boot/config.txt'

• So the full LIRC setup would be.

sudo apt-get install lirc
sudo /bin/sh -c 'printf "\n\nlirc_dev\nlirc_rpi gpio_in_pin=23 gpio_out_pin=22" >> /etc/modules'
sudo rm /etc/lirc/hardware.conf
sudo /bin/sh -c 'printf "########################################################\n# /etc/lirc/hardware.conf\n#\n# Arguments which will be used when launching lircd\nLIRCD_ARGS=\"--uinput\"\n\n# Do not start lircmd even if there seems to be a good config file\n# START_LIRCMD=false\n\n# Do not start irexec, even if a good config file seems to exist.\n# START_IREXEC=false\n\n# Try to load appropriate kernel modules\nLOAD_MODULES=true\n\n# Run \"lircd --driver=help\" for a list of supported drivers.\nDRIVER=\"default\"\n# usually /dev/lirc0 is the correct setting for systems using udev\nDEVICE=\"/dev/lirc0\"\nMODULES=\"lirc_rpi\"\n\n# Default configuration files for your hardware if any\nLIRCD_CONF=\"\"\nLIRCMD_CONF=\"\"\n########################################################" >> /etc/lirc/hardware.conf'
