Hello everyone, today I am going to demonstrate some shell script tips and tricks. On my previous post, I have shown a simple shell script "Hello World" that can be read here. After we create a script, we need to make the script executable before we can actually run it.
For example, we already have a .sh file called hello.sh which contains some line of codes. We need to make the hello.sh file executable. Use the following command to make the hello.sh executable.
sudo chmod +x hello.sh
Now we can run the script with this command
sh hello.sh
or
./hello.sh
Its pretty simple but for a beginner, you must know it.
