OR expression

Hi all,

I want to perform 'OR' for the following 3 variables.

rc1=1
rc2=1
rc3=1

rc=`${rc1} \| ${rc2} \| ${rc2} `

How can it be done?

Thanks,
Rock

I have amended the script as below.

rc=`expr ${rc1}` || `expr ${rc2}` || `expr ${rc3}`


But the following error prompted.

/work/proj/projtmp/testing.sh[3]: 1: not found.


Please give me some instructures for making 'OR' for these variable.

Thanks,
Rock

Code:
a=$(( 0 | 2 | 4 ))
echo $a
6

This is an arithmetic "or", is that what you want?
