The script doesn’t actually do anything in its first run, so it needs to be started by its owner. So in order to do so, you need to find some user account of the system that you want to run the script on. If you don’t know how to do this, you could use the shell command ls -l /tmp, and if you want to create an alias to do it for you, you could create one yourself. I’ll explain the process one by one. I’ll start with the command itself.
#!/bin/bash if [ -z “$1” ] then exit 1 fi sleep 10 else echo `date` fi
Now, I’ll explain how to create an alias for the script, and then explain how to change the script itself. Before that though, I want to explain what we should be thinking about when we create the alias.
It’s a little strange to talk about alias. What should we be thinking about?
What’s the target user?
If we look inside the script, there’s a lot of text that just refers to the root user, including the /etc/shadow and /opt/shadow files. The last part of the script can even make reference to other users, with the following line:
That’s what should be our target user, if we want to run the script on the system that is currently root:
cd /var/bin # You’ll need to replace /var with the folder where you want to store the files cd /bin
It’s important to know that the variable $1 doesn’t exist in the script, so if you want to test it out, just change the variable to the name of your system user. That means you’ll have to edit /var/share/bashrc first.
Now, the $1 itself, is a shell variable. It isn’t actually set here, it exists as a reference to the executable, and it needs to be set before all the other variables mentioned earlier. So we need to find an executable that matches the name of the system user, and then change the $1 variable to the executable we want to run this script at the system’s command. So we can use the following:
if [ “!/bin/dash” ! == “0” ] then echo “bash: system-uid “$1″ should be set as root” fi if [ “$1”
