In one of my script, I would like to check the RETCD like this,

If the RETCD is not 0 and (RETCD is not 2310 or 2314 )
I want it do something in my script.

I have written a small script for that, but it is telling me syntax error.
Can somebody fix this or you may write all the way newone and provide me.

#!/bin/ksh

echo "type a number a"

read a
let RETCD=a
if [ $RETCD -ne 0  &&  [[ $RETCD -ne 2314 || $RETCD -ne 2310 ]] 
]
then
echo "the retcd is not 0 or 2314 or 2310"
else
echo "the retcd is $RETCD"
fi

If I run the above script, I get this error. It is not accepting the syntax.
u060wdb1:/tmp>./1.ksh
type a number a
2333
./1.ksh[8]: 0403-057 Syntax error at line 9 : `]' is not expected.
u060wdb1:/tmp>


Thanks in advnace

Either:

case $RETCD in
0|2314|2310) print "the retcd is $RETCD";;
*) print "the retcd is not 0 or 2314 or 2310";;
esac

or

if ((RETCD != 0 && RETCD != 2314 && RETCD != 2310)); then
echo "the retcd is not 0 or 2314 or 2310"
else
echo "the retcd is $RETCD"
fi

Which is the same as satisfying all of $RETCD -ne 0, $RETCD -ne
2310, and $RETCD -ne 2314.

Which is what Stephane's case statement does.

If you don't agree, please provide a value for $RETCD which
satisfies your conditions, but not Stephane's.

In what way does it not satisfy the requirement?

No, it's the same as satisfying $RETCD -ne 0.  Which makes me think
the OP does not have a clear idea of what the requirements actually
are.

One way of fixing your syntax would look like this:
if [ "$RETCD" != 0 ] && { [ "$RETCD" != 2314 ] || [ "$RETCD
" != 2310 ]; }

But the { ... } part is always true (2310 satisfies the first part,
and thus the whole; 2314 satisfies the second part, and thus the
whole; every other value satisfies both parts, and thus the whole), so
this is equivalent to:
if [ "$RETCD" != 0 ]
