How can you compile and execute shell scripts in unix?
Shell scripts are plain text files; they do not need to be compiled. To make these scripts executable, you need to add an executable flag using chmod. Consider the following example: $ chmod +x myscript
- Open the terminal. Go to the directory where you want to create your script.
- Create a file with . sh extension.
- Write the script in the file using an editor.
- Make the script executable with command chmod +x <fileName>.
- Run the script using ./<fileName>.
- ps -p $$ – Display your current shell name reliably.
- echo "$SHELL" – Print the shell for the current user but not necessarily the shell that is running at the movement.
- Create a file using a vi editor(or any other editor). Name script file with extension . sh.
- Start the script with #! /bin/sh.
- Write some code.
