Hi All,

Can some one tell me how to get run the following:

data1="hello"
data2="world"
if [ "$data2" != "world" && "$data1" != "hello"]
then
{
echo "good afternnon"
}
else
{
echo " good morning"
}
fi

The above code gives me an error ad below :
./if.h: line 3: [: missing `]'

Thanks in advance

Dear jisha,

try this

data1="hello"
data2="world"
if [ "$data2" != "world" ]
then
if [ "$data1" != "hello" ]
then
echo "good afternnon"
fi
else

echo " good morning"

fi

try:

if [ "$data2" != "world" ] && [ "$data1" != "hello" ]

Don't forget to let a space before ] and after [ !
Here is the code :

data1="hello"
data2="world"
if [ "$data2" != "world" ] && [ "$data1" != "hello" ]
then
{
        echo "good afternnon"
}
else
{
        echo " good morning"
}
fi

If you want to make your schell script more efficient you should use the shell builtins

#!/usr/bin/ksh

data1="hello"
data2="world"

if [[ "$data2" != "world" && "$data1" != "hello" ]]
then
    print "good afternnon"
else
    print "good morning"
fi

u can also use this one:)

if [ "$data2" != "world" ] -a [ "$data1" != "hello" ]
