How to compare the value of a variable with a string in the shell script

Navigation

Well, I'm trying to make a comparison like this but bash is interpreting it as a command 

if "$V1" = "sim"
then
  ...

How do I compare the value of V1 with the string "yes":

The syntax of your if is incorrect, the right one is: 

if [ "$V1" = "sim" ]; then
....

1) Simple block: 

if [ "$V1" == "sim" ]; then
    echo "Sim!"
fi

In a row: 

[ "$V1" == "sim" ] && echo "Sim!"

2) Block if/else : 

if [ "$V1" == "sim" ]; then
    echo "Sim!"
else
    echo "Nao!"
fi

In a row: 

[ "$V1" == "sim" ] && echo "Sim!" || echo "Nao!"
