#!/bin/sh echo -e "Please enter your name: \c" read NAME echo "Your name is $NAME." exit 0The c means that the line feed will be suppressed, so that the prompt sits at the end of the line, not at the beginning of the following line.
Two more common controls available to the echo command are to use n to add a line feed, and t to add a tab.
Multiple values may be read on a single line by using:
#!/bin/sh echo -e "Please enter two numbers: \c" read NUM1 NUM2 echo The numbers entered are $NUM1 and $NUM2 exit 0This ensures that if two numbers are entered on a single line, they will be read within two variables. If three numbers were entered, the second variable (NUM2) would contain the last two numbers.
Assuming three numbers were the input of the above example, the first two numbers could be assigned to the first variable by entering them as
num1 num2 num3
The backslash () allows the blank space between num1 and num2 to be part of the variable (ordinarily, spaces are used as field seperators.
