Case Insensitive search
Hey , i am trying to do a search for the certain books , and im trying to make it case insensitive. what i have come up with so far is this :

Code:
Database.txt
RETARDED MONKEY:RACHEAL ABRAHAML:30:30:20
GOLD:FATIN:23.20:12:3
STUPID:JERLYN:20:40:3



Code:
echo -n "Title: "
read Title
echo -n "Author:"
read Author
echo ""
 
valuecheck=`grep -i "$Title" Database.txt | grep -i "$Author"  | awk -F":" '{ print $1}'`
echo $valuecheck
if [ $Title = $valuecheck ] ; then

echo "HOHOHO"
else 
echo "too bad"

fi

the issue which i am having is that, when it does the search for the correct row to be inputted into valuecheck , it will input the value as written in the database, which is in Uppercase.

For this case, if i type in stupid for $Title and jerlyn for $Author, it searches the correct row, but the awk will print "STUPID" into the variable as that is what is written in the database.

so how can i make my if statement case insensitive? currently it reads like this
i
Code:
f [ $Title = $valuecheck ] ; then

which means

if [stupid = STUPID ] ; then

how can i make it case insensitive to allow it to display "HOHOHO"

NOTMUCH-HOOKS(5)						File Formats Manual						  NOTMUCH-HOOKS(5)

NAME

       notmuch-hooks - hooks for notmuch

SYNOPSIS

	$DATABASEDIR/.notmuch/hooks/*

DESCRIPTION

       Hooks  are  scripts  (or  arbitrary  executables  or symlinks to such) that notmuch invokes before and after certain actions. These scripts
       reside in the .notmuch/hooks directory within the database directory and must have executable permissions.

       The currently available hooks are described below.

	   pre-new
	       This hook is invoked by the new command before scanning or importing new messages into the database. If this hook exits with a non-
	       zero status, notmuch will abort further processing of the new command.

	       Typically this hook is used for fetching or delivering new mail to be imported into the database.

	   post-new
	       This hook is invoked by the new command after new messages have been imported into the database and initial tags have been applied.
	       The hook will not be run if there have been any errors during the scan or import.

	       Typically this hook is used to perform additional query-based tagging on the imported messages.
