multiple word check
Hi

left value is 1.34 and i want it to compare against 4 right values 2.01, 3.01. 4.09 ,1.11 . This is not numerical comparion. I need for text. I get syntax errors ...

value =1.34 --> value will be passed dynamically..
Code:
 
if [ $value -eq "2.01|3.01|4.09|1.11|orange" ]   --> is this correct ?
{}
else
{}fi

Code:
$ cat Test
value=${1:-0}

case "$value" in
  2.01|3.01|4.09|1.11|orange) echo "Do something...";;
  *) echo "Do something else..."
esac

$ ./Test ora
Do something else

$ ./Test 2.99
Do something else

$ ./Test orange
Do something...

$ ./Test 3.01
Do something...

What shell are you using - what is meant by {} ?

Also, what is meant by "left value" and "right value", and by "value will be passed dynamically"?. Dynamically how?

To check whether it matches any of the values:

Code:
case $value in
     2.01|3.01|4.09|1.11|orange) echo Match ;;
     *) echo no match ;;
esac

To check which, if any, of the values it matches:

Code:
case $value in
     2.01 )  : whatever ;;
     3.01 )  : whatever ;;
     4.09 )  : whatever ;;
     1.11 )  : whatever ;;
     orange) : whatever ;;
     *)   echo no match ;;
esac
