Bash if Multiple Conditions, To check multiple conditions in a Bash if statement, you can use the && (AND) and || (OR) operators. The && operator returns true only if both of its operands are true. The || operator returns true if either of its operands are true. To use the && and || operators in an if statement, you simply separate the conditions with the appropriate operator. For example, the following if statement checks if the file myfile.txt exists and if the user has permission to read the file: Bash #!/bin/bash # Check if the file 'myfile.txt' exists and if the user has permission to read it if [[ -f "myfile.txt" && -r "myfile.txt" ]]; then # The file exists and the user has permission to read it echo "The file 'myfile.txt' exists and you have permission to read it." fi Use code with caution. Learn more If the file myfile.txt exists and the user has permission to read the file, the script will print the message "The file 'myfile.txt' exists and you have permission to read it." to the terminal. You can also use the if..elif..else statement to check multiple conditions in Bash. The if..elif..else statement checks the conditions in order and executes the first block of code for which the condition is true. If none of the conditions are true, the else block is executed. Here is an example of a simple Bash if..elif..else statement:
