I'm trying to execute a script called "testing" on startup of my SUSE reboot. So I placed this simple script to '/etc/init.d'
The code is like this
#!/bin/bash
# ScriptName=testing
cat > ~/output << "EOF"
This text is generated on startup!!
EOF
After that, I execute these command
chmod +x /etc/init.d/testing
touch /etc/rc.d/rc3.d/S12testing
But after I reboot the system, nothing happened.
There must be something I missed out.
Here is the reference I searched.
chmod +x /etc/init.d/testing
touch /etc/init.d/rc.d/rc3.d/S12testing
Should not be 'touch', but a symbolic link (ln -s) to /etc/init.d/testing.
Try
cd /etc/init.d/rc.d/rc3.d
ln -s ../../testing S12testing
Hope this helps.

My code file looks as follows
Cd testR
Mkdir bin
chmod -R 755 bin
Sudo su - inst1
cp inst1/installable/files/testR.p
...
...
So after sudo su the execution get paused please let me know what should i do
If there is no problem that your commands are executing as root, you can execute your script like this:
sudo ./yourscript
So, you don't have to switch within your shell script.
In my .bashrc I'm using .sh script for easily configuring newly installed Debian. But while trying to
rm -f ~/.bash_aliases
wget https://raw.githubusercontent.com/.../.bash_aliases
rm -f ~/.bashrc
wget https://raw.githubusercontent.com/.../.bashrc
it's just omitting those line?
File is with permission chmod +x ./script.sh and run by sudo ./script.sh
What could possibly be wrong?
(In final code there is full link, files are being downloaded as .bashrc.1 and .bash_aliases.1)
Don't use sudo unless you have a good reason.
When you run sudo ./script.sh it runs as root, so ~ refers to root's home directory /root instead of your user's home directory.
Just run ./script.sh instead, so that it runs as you and modifies your own home directory.
I am a new Ubuntu user.
Recently, I try to set up a server on Ubuntu.
I am wondering how to write a automatically script to run a series of script one by one.
For example, I need to install squid first, after that I need to make a copy of config file then modify the file. The following are the steps that I write in the command console. I wonder how to make a script to run that automatically.
sudo apt-get install squid -y;
cd /etc/squid3;
sudo cp squid.conf squid.conf.bak;
sudo rm -rf squid.conf;
sudo nano squid.conf
Just add a shebang, place everything in a ".sh" file, make the file executable, and run it...
Save this as test.sh
#!/bin/bash
sudo apt-get install squid -y;
cd /etc/squid3;
sudo cp squid.conf squid.conf.bak;
sudo rm -rf squid.conf;
sudo nano squid.conf
Make it executable chmod +x test.sh
Run it... ./test.sh
To edit the file from a terminal
Get a terminal on the box where you want the script to live. Probably you will SSH into it.
Then just cd to the path you want the script to live and do the following...
nano test.sh This opens the nano terminal text editor.
Copy the above test.sh commands, make sure to get the shebang (#!/bin/bash).
Paste the script into the nano editor, you'll need to use ctrl+v or cmd+v.
Hit the key combination of ctrl + o, hit the enter key.
Hit the key combination of ctrl + w. This exits nano. Proceed with the abov instructions.
I suggest you read up on nano so you can get more familiar with its abilities as it can save a lot of time!
I have wrote some script for my VPS and this is a example for Squid3
#!/bin/bash
function add_user () {
while true; do
echo -e "\nInsert a name for the Squid3 user (0=exit): \c"
read utente
case "$utente" in
0)
echo -e "\nGoodbye $USER!\n"
exit 0
;;
*\ *)
echo -e "\nYou can't use spaces in the name!"
sleep 2
continue
;;
*)
break
;;
esac
done
if [ ! -e '/etc/squid3/.passwd' ]; then
sudo htpasswd -c /etc/squid3/.passwd $utente
else
sudo htpasswd /etc/squid3/.passwd $utente
fi
}
function installer () {
sudo apt-get install squid3 apache2-utils -y
sudo bash -c "echo 'here
you
must
paste
your
configuration
file' > /etc/squid3/squid.conf"
sudo service squid3 restart
}
if ! [ "$(sudo which squid3)" ]; then
installer
add_user
else
add_user
fi
First run it install squid3 and apache2-utils (for htpasswd) and after make a new user.
If you run it again you can add more users.
I am trying to make cgMiner auto-start when my Raspberry Pi (Raspbian Linux) starts.
Edited the rc.local file:
sudo nano /etc/rc.local
and added this line:
nohup ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1 >/dev/null 2>&1&
and cgMiner doesn't start. If I type in terminal the exact same line with sudo in front it works perfectly.
sudo nohup ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1 >/dev/null 2>&1&
What can I do?
I think it is related to the path or better the current working directory.
You are using ./cgminer and not a full path. So either use the full path or first cd to the directory containing the cgminer program.
Also have a look at the following page over at adafruit doing the exact same thing you are trying to accomplish
http://learn.adafruit.com/piminer-raspberry-pi-bitcoin-miner/configure-auto-start
Adafruit has the following code in /etc/rc.local
cd /home/pi/PiMiner
python PiMiner.py &
cd ..
nohup ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1 >/dev/null 2>&1&
The first and third line (the cd commands) ensure that the folder containing the folder containing the cgminer command is the current directory.
From the two cd commands adding the following command before the line containing the cgminer command would solve your issue
cd /home/pi
I seem to have found the solution for this problem, assuming it is the same as for bfgminer.
After spending a full day playing with init.d scripts, I found the simplest way is to make sure your cgminier.conf file has all the arguments in then add the following to the end of /etc/rc.local
cd /home/YOURNAME/bfgminer
sudo ./bfgminer
It ran without the sudo part, but didn't start up my block erupter without it.
I also managed to get it running from init.d, but had issues with it preventing system rebooting when done that way.
Hope that helps
ok I am writing my first bash script in ubuntu 10.04.
The file is on my desktop: /home/myuser/Desktop
The file is called hello-world
The file contains:
#!/bin/bash
echo "Hello World"
I open a command line and run:
/home/myuser/Desktop/hello-world
It tells me permition is denied. So I run it again with sudo, it asks me for my password, I type it in, hit return.
I get this output.
sudo:
/home/myuser/Desktop/hello-world:
command not found
What am I doing wrong?
Your script probably is not set to be executable. Try:
chmod u+x /home/myuser/Desktop/hello-world
If your script is called test.sh then do the following...
$ chmod +x test.sh
followed by
$ ./test.sh
chmod +x hello-world
You need to mark the script as executable. Run chmod +x hello-world to add the executable bit.
You can also do:
sh /home/myuser/Desktop/hello-world
which will execute the script without it needing to be set as executable.
