To change permissions on a shell script, you can use the chmod command in the terminal. For example, to make a script executable, you would run chmod +x script.sh. You can also set specific permissions by using numeric values, such as chmod 755 script.sh, which grants read, write, and execute permissions to the owner and read and execute permissions to the group and others.

Why are setuid shell script inherently unsafe?
Setuid shell scripts are inherently unsafe because they can be exploited to escalate privileges. When a script is executed with setuid, it runs with the permissions of the file owner, potentially allowing an unprivileged user to execute commands that they normally wouldn't have access to. If the script contains vulnerabilities, such as improper handling of input or environment variables, an attacker can manipulate it to execute arbitrary code with elevated privileges. This risk is compounded by the unpredictable nature of shell environments, making it difficult to ensure safe execution.
Write a shell program to check read and write permissions of a file?
You don't say what you want to do with the permissions, but most shells have a 'test' command that can look at various permissions. Look at the 'man' command for the shell you are running in to see what tests are possible on files and directories. You can check to see if the target is a directory, or a file, and whether it has read, write, or execute/search permissions. Again, it varies by the shell environment.

What is the Purpose of exit command in Shell of Unix?
The 'exit' command allows you to stop a running shell script at any point and to return a "status" value back to whomever called the shell script. This is a very common practice with shell scripts; sometimes you want to stop the script before it gets to the end of the shell script (for various logic reasons). The 'exit' command also allows you to give a status that any other calling process can use to determine if the shell script ended successfully or not.
