how to run a specific command via a bash script and add in to a startup

Question

I want to execute this command in Ubuntu 14.04

sudo ./crclient -u username -i eth0

I will use it for login in cyberrom client. So need some help to create a bash script and add in to a startup like windows startup.

quick question, does the user need to input his/her own username? — patrick, Jul 29 '16 at 06:58
Yes its ok for me I just want to login through command and add into a startup — Tech T, Jul 29 '16 at 07:18

Here is the code you want to make in a shell script.

#!/bin/sh echo -n "Enter your username and press enter: " read name sudo ./crclient -u $name -i eth0

in ubuntu open dash (the ubuntu button) and type startup

then you get this:

Press add and type at the command rule:

incase of the ubuntu terminal gnome-terminal -x "sh /path/to/script.sh"

incase of xterm (which i prefer) xterm -e "sh /path/to/your/script.sh"

then reboot and see if it works :)

---------------------------EDIT---------------------------

make a new file in /etc/xdg/autostart using nano/vi or a text editor and name it test.dekstop

copy this into it

[Desktop Entry] Name=MyScript GenericName=test Comment=test Exec=/path/to/my/script.sh Terminal=true Type=Application X-GNOME-Autostart-enabled=true

reboot the pc afterwards

______________________EDIT 2______________________

To allow the command to run without sudo asking for a password, do the following:

visudo

scroll all the way down and add this

linuxusername ALL= NOPASSWD: path/to/crclient

save and exit

Code is running perfectly but while running getting this error [ > ./cyberrom.sh: line 1: !/bin/sh: No such file or directory ] and after that its asking user name but its worked and i also added in startup and reboot but is not prompting that screen – Tech T Jul 29 '16 at 07:58
I see what happened :P Add # before !/bin/sh so you get #!/bin/sh – patrick Jul 29 '16 at 07:59
I forgot to add that to the code, my bad! – patrick Jul 29 '16 at 08:00
after adding #!/bin/sh now its working and is it possible to add password to same code?? – Tech T Jul 29 '16 at 08:04
that the user him/herself puts in? if so, post the command with the string the user adds for a passcode – patrick Jul 29 '16 at 08:04
ok lemme phrase it this way,
sudo ./crclient -u username -i eth0

that's the command, but how does one enter the password?

sudo ./crclient -u username -i eth0 -p password?
– patrick Jul 29 '16 at 08:07
what im asking is, what command do they input if they add a password – patrick Jul 29 '16 at 08:09
wait... let me chk once with configuration file – Tech T Jul 29 '16 at 08:11
yep, yep yep yep! – patrick Jul 29 '16 at 08:12
forget about password thing that i managed with configuration file now everything is perfect expect startup thing so need some more help – Tech T Jul 29 '16 at 08:17
did you do this one?
xterm -e "sh /path/to/your/script.sh"

or

gnome-terminal -x "sh /path/to/script.sh"

the xterm one only works with the xterm program, the gnome-terminal one is the one you need if you don't have xterm
– patrick Jul 29 '16 at 08:17
i already did gnome-terminal its working perfectly but that screen i want add in a startup – Tech T Jul 29 '16 at 08:22
what screen? can you eloberate? – patrick Jul 29 '16 at 08:24
its asking user name – Tech T Jul 29 '16 at 08:25
Hold on, I am confused at this point, what it should do is open a terminal asking for the username, you enter your username and then it start the program, does it do that? – patrick Jul 29 '16 at 08:27
yes my program is working when i entered user name.. but now i want that code to run in startup basically i want pop up that code so whenever restart my system it will prompt me with that code like pop up – Tech T Jul 29 '16 at 08:32
just follow the tutorial I posted, or does it not work? – patrick Jul 29 '16 at 08:32
its not worked i already try – Tech T Jul 29 '16 at 08:36

– Tech T Jul 29 '16 at 08:41
no its just example – Tech T Jul 29 '16 at 08:42
i see, you need to do this :)
name: abc command: gnome-terminal -x "sh /path/to/script.sh" comment: Testoroonie
– patrick Jul 29 '16 at 08:42
ok look at the tutorial i am editing it – patrick Jul 29 '16 at 08:46
Sry for the late reply..i have checked when i was run the script normally ./ it will ask me 3 steps 1 user name 2 sudo password 3 cyberrom password and its working 100% but after reboot in startup showing only 2 steps 1 username and sudo password so i think there is any startup command issue – Tech T Jul 29 '16 at 09:06
ok try this change Exec=/path/to/my/script.sh to Exec=gnome-terminal -x "/path/to/my/script.sh" – patrick Jul 29 '16 at 09:07
also if you want you can remove the sudo password :) – patrick Jul 29 '16 at 09:09
no its not working via Exec=gnome-terminal command even its not working stratup as well – Tech T Jul 29 '16 at 09:16
Exec=gnome-terminal command via terminal its working perfectly – Tech T Jul 29 '16 at 09:18
ok question, do you mind installing xterm? – patrick Jul 29 '16 at 09:21
xterm is alredy installed in my system – Tech T Jul 29 '16 at 09:23
ok ok :) go back to the gui startup menu like in the tutorial and as command do xterm -e "sh /path/to/script.sh" – patrick Jul 29 '16 at 09:24
this command is not working it will ask only username and sudo password – Tech T Jul 29 '16 at 09:26
hrm.... then i do not know anymore, i am sorry my friend :/ – patrick Jul 29 '16 at 09:27
Its ok #patrick thnks for your help... thank you so much once again – Tech T Jul 29 '16 at 09:36

yes you are right :) – Tech T Jul 29 '16 at 09:37
