Shell script - If---fi condition

yog_chavan · #1 (**permalink**) 05-07-2008

Hi All,

My current if statement is like mentioned below. But there is posibility that plant value which are currently only two i.e. ESAP and VAL will be more. I do not want to add OR condition every time. Is there any way, I can use only one bracket and go on adding new values. something like this.
if [ $PLANT eq ESAP VAL VAL1 VAL2......]. I am not aware of exact syntax. Could you please let me know.
================================
if [ $PLANT = ESAP -o $PLANT = VAL ]
then
do something
else
do something
fi
================================

hi aju kup

I dont want to keep on adding OR condition. If anybody aware of basic SQL, then there it is possible to mention like..

PLANT IN ( 'ESAP','VAL','VAL1,'VAL2'...........)

Something like this possible????

Code:

plant="ESAP VAL VAL1 VAL2"

echo $plant | grep ESAP >/dev/null

if [ $? == 0 ]
then
do something
else 
do something
fi

this is what case statements are for.

Code:

#!/usr/bin/ksh
PLANT=$1

case $PLANT in

        ESAP|VAL)
                print do something
                ;;
        *)
                print do nothing
                ;;
esac

$ ./match VAL
do something
$ ./match ESAP
do something
$ ./match abc
do nothing
