How to use logical operators in multiple if statement
Hi
I want to send a status mail if daily or weekly or monthly batch completed or aborted. Here is the code.

Code:
if [ "$BatchFrequency" = "Daily" ] && [ "$ModuleBusinessName" = "XYZ" ] && 
[ "$Status" = "COMPLETED SUCESSFULLY" ]  || [ "$Status" = "ABORTED" ]  

Else if  [ "$BatchFrequency" = "Weekly" ] && [ "$ModuleBusinessName" = "ABC" ] 
&& [ "$Status" = "COMP LETED SUCESSFULLY" ]  || [ "$Status" = "ABORTED" ]  

Else if  [ "$BatchFrequency" = "Monthly" ] && [ "$ModuleBusinessN ame" = "PQR" ] 
&& [ $Status" = "COMPLETED SUCESSFULLY" ] || [ "$Status" = "ABORTED" ] 
then
mailx –s “Status Report” sumone@sumthing.com 
else 
print  ”try again”

Plz suggest the changes.

Code:
for AND (&&) use --> "-a" option
for OR (||) use --> "-o" option
eg.,
if [ "$BatchFrequency" = "Daily" -a "$ModuleBusinessName" = "XYZ" -a "$Status" = "COMPLETED SUCESSFULLY" -o "$Status" = "ABORTED" ]

i think, this might help you.

The logical AND and OR conditions will remain same. Use "elif" in place of "Else if" and after the final else with the associated statement end the if block with "fi" .

Eg:

Code:
if [ $int1 = $int2 ]
then
       echo "int1 is equal to int2"
elif [ $int1 > $int2 ]
then
       echo "int1 is greater than int2"
else
     echo "int1 is smaller than int2"
fi

Alternative Way:

is equal to: eq
is not equal to: ne
is greater than: gt
is less than: lt
is greater than or equal to: ge
is less than or equal to: le

-a is same as using &&
-o is same as using ||

Note: Padding of space is mandatory before using '[' and ']'

Thank you.

Place the mail part script in a function and try for checking the conditions..
And if your using double square brackets then use && or || , for single square bracket you can use -a or -o
Code:
 #!/bin/ksh
func_mail()
{
 mailx -s “Status Report” sumone@sumthing.com 
}
 
if [[ "$BatchFrequency" = "Daily" && "$ModuleBusinessName" = "XYZ" && "$Status" = "COMPLETED SUCESSFULLY" || "$Status" = "ABORTED"  ]]
then
        func_mail
elsif [[ "$BatchFrequency" = "Weekly" && "$ModuleBusinessName" = "ABC" && "$Status" = "COMPLETED SUCESSFULLY" ||"$Status" = "ABORTED" ]]
then
       func_mail
elsif [[ "$BatchFrequency" = "Monthly" && "$ModuleBusinessName" = "YUI" && "$Status" = "COMPLETED SUCESSFULLY" ||"$Status" = "ABORTED" ]]
then
       func_mail
else
       echo "Try again"
fi
