How can i get this script working?

  • 772

The Script(input.sh):

echo "What is your name?"

if [[ $1 =~ "*" ]]
then
read name1
read name2
echo "Are you really "$name1 "??? or" $name2 "?"
else
echo "Are you really "$1 "??? or" $2 "?"
fi

What I want is if I run the command:./input.sh fahad Eclipse

Then it should print: 

What is your name?
Are you really fahad ??? or Eclipse ?

Also, if I do this: ./input.sh

Then it should ask me for input and then print the line.

How can I do that ?

command-line

    Your script isn't executing properly due to your if statement, the following should work. It requires 2 args, or it will ask them name1 and name2.

    The if statement contains '$#' which calculates the number of arguments given. The follow '-ne' is the comparison operator for 'not equal to'. Finally the last number is for how many you're expecting. So in our case, we're looking for exactly 2, if 1, or 4 are given, the else statement will be executed. 

    #!/bin/bash
echo "What is your name?"

if [[ $# -ne 2 ]] ; then
read name1
read name2
echo "Are you really "$name1 "??? or" $name2 "?"
else
echo "Are you really "$1 "??? or" $2 "?"
fi
