If Then Else Statement Help

[Jeff Paciolla_1]

This is probably a very simple question, but any help will be appreciated. Does anybody have an example of an if statement where the variable could be more than one value.

Here is an example one value that works.
******************************
NAME=$1

if [ $NAME = "John" ] ; then
echo $NAME
else
exit 0
fi
****************************

What i need to do is add another possible value in the if statement where $NAME could equal "John or "Jane".

I can't seem to get the syntax correct.

Thanks
Jeff

Hi Jeff:

How about this:

if [ "$I" = jim -o "$I" = james ]
then
echo "that's me!"
else
echo "I am not me"
fi

#!/usr/bin/ksh

export NAME=$1

if [ $NAME = "John" ] ; then
echo "John $NAME "
elif [ $NAME = "Jane" ] ; then
echo "Jane: $NAME"
exit 0
fi

(man ksh / look for case if there is multiple options)
Later,
Bill

James - What does the -o do in the if statement?
Thanks

Hiya,

Try

if [ "$NAME" = "John" || "$NAME" = "Jane"] ; then
echo $NAME
else
exit 0
fi

I think && is the AND....

Note that the /sbin/init.d directory has loads of HP startup scripts that are a good start to look for syntax :-)

Cheers,
James

Hi Jeff:

if [ "${name}" = "John" -o "${name}" = "Jane" ]
then
echo "Ok"
else
echo "Bad"
fi

Note the quotes around "${name}" - they protect you in case the variable is ever null;

Here's a variant with numeric comparisons using and

if [ ${a} -ge 1 -a ${a} -le 10 ]
then
echo "${a} is in range"
else
echo "${a} is out of range"
fi

use -o option for giving the OR choice.
[ $NAME = "John" -o $NAME = "Jane" ]

everything else remaining the same.

(you can do a man on ksh for other related
options)

This could work too ..

[[ $NAME = John || $NAME = Jane ]] && echo $NAME || exit

A one-liner without the "if" and the "then"

-o stands For OR ... -a => AND

All the best

Hi Jeff:

The '-o' is "or". '-a' denotes "and". Have a look at the man pages for 'test' ('man test').
