Some error in Korn shell script

HI
I am getting this weird error in the korn shell script

if [[[$region = "SW"] && [$family_type = "DS1"]]]
then

case "$family_subtype" in
NLFW)
echo "calling script..."
S-T-SW-DS1-1.sh
;;
NLNW)
echo "calling script..."
S-T-SW-DS1-2.sh
;;
DSCL)
echo "calling script..."
S-T-SW-DS1-3.sh
;;
REML)
echo "calling script..."
S-T-SW-DS1-4.sh
;;
OSML)
echo "calling script..."
S-T-SW-DS1-5.sh
;;
TBD)
echo "calling script..."
S-T-SW-DS1-6.sh
;;
esac
fi


and the error is

[[[SW = SW]
mapping.sh[21]: [[[SW: not found


Can anyone help me

 

Do you not need ./ when calling scripts?

 

I am least concerned on ./ .
My question is related in the IF loop
and yes u dont need ./ to run a shell script on korn shell

 

It was worth a try Sorry I couldn't be more help.

 

Your test statement [[ should be post-fixed by at least one space and the other ]] preceded by a space. For example:

Code:

[[ condition1 && condition2 ]]

I would use ( and ) for the bracketing of conditions in a test statement. Thus your code is:

Code:

if [[ ($region = "SW") && ($family_type = "DS1") ]] ; then

 

i dont know why but in my korn shell ( and ) are not supported.
Please be assured that i have tried all possible brackets in every way to run my script

 

Did you put the spaces after the [[ and before the ]]?

 

No, i havent used spaces near the [[ & ]]
