how do I get the value of expr with ksh

Hi,

I have written a korn shell script to compute the value of k.

formulae :

a=10
b=20
c=30
k=(a+b)*c

my shell script is :

a=10
b=20
c=30
k=`expr (($a + $b ) * $c )`
echo $k

### here paranthesis ( ) not accepting by expr function.
### if i remove paranthesis, the value will be 610(wrong)
### but the actual value should be 900

please give me solution to kkodava@maxis.com.my

thanks

krishna

NAME
script-email - Amanda script to send email notifications DESCRIPTION
script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the addresses specified in the MAILTO property. PROPERTIES
This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API, script configuration. MAILTO List of email addresses that will receive an email on command execution. It is a multi-valued property: property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com" EXAMPLE
In this example, script-email is scheduled to be run before the DLE, on the server. The unqualified email address amanda will be passed to the email system unchanged. The script is then attached to a dumptype, which can then be specified for any DLEs which require notification. define script-tool pre-email { comment "email me before this DLE is backed up" plugin "script-email" execute-on pre-dle-backup execute-where server property "mailto" "amanda" } define dumptype user-tar-email { user-tar script "pre-email" } SEE ALSO
