    Echo Command in Linux

    In Linux, the echo command is used to show a line of text/string that has been supplied as an argument. This is a built-in command that outputs status text to the screen or a file. It's typically used in shell scripts and batch files. The syntax for this command is "echo [option] [string]".

    Options with Echo command

    1. \b

    it eliminates all the spaces in between the text

    Example :

    echo -e "hello \bdevelopers"

    2. \c

    To continue without emitting a new line, use the backspace interpreter '-e' to suppress the trailing new line.

    Example :

    echo -e "hello \cdevelopers"

    3. \n

    This option generates a new line from the current one.

    Example :

    echo -e "hello \ndevelopers"

    Example :

    echo -e "hello \tdevelopers"
