Question

What is the Linux command to read input, not passed as a command-line argument?

1) read
2) input
3) scanf
4) gets

Answer 1

The correct Linux command to read input not passed as a command-line argument is 'read'. It waits for user input and can save the input to a variable.

Step-by-step explanation:

The Linux command to read input not passed as a command-line argument is read. When you use this command in a script or in the terminal, it waits for input from the user. After the input is provided and the Enter key is pressed, the input can be stored in a variable for further use within the script or program. Unlike read, 'input', 'scanf', and 'gets' are not the correct commands for this operation in a typical bash shell environment on Linux.
