Making expr match case insensitive...
here is the condition i am using
Code:
 [[ `expr match "$line11" ".*INDEX.*"` = "0" ]]

how to make this case insesntive... that is it should work with smaller case of "index" too...

Try this:
Code:
echo $line11 | grep -iq "INDEX"
[[ $? != 0 ]] #### implies $line11 doesn't contain INDEX

i have something like this..
Code:
if [[ `expr match "$line11" ".*INDEX.*"` = "0" ]] && [[ `expr match "$line11" ".*PRIMARY.*"` = "0" ]] 
&& [[ `expr match "$line11" ".*UNIQUE INDEX.*"` = "0" ]] && 
[[ `expr match "$line11" ".*KEY.*"` = "0" ]]; then

so for this could i use
Code:
if [[ echo $line11 | grep -q -i "index" ]] && [[ echo $line11 |grep -q -i "unique index" ]] && etc etc

would this work??

I see that you're searching if the words 'index', 'unique index' and 'key' are present in $line11, am I right? Why not wrap it up in a single statement, something like this:

Code:
echo $line11 | grep -iq ".*index.*unique index.*key.*"
[[ $? == 0 ]] #### implies match found

yeah somewhat like that.. but how to negate this.. cause if you observer i am doing this
Code:
[[ `expr match "$line11" ".*INDEX.*"` = "0" ]]

that is if its 0 then that line doesnt have INDEX word in it... in some other part of the code i needed to check if it HAS those words too so i will have to use the above technique which you said... :-)
