Shell Programming and Scripting

Hey everyone, I kinda new to shell programming and learning bits and pieces of stuff from tutorials.

I got this problem, where I asked my user to enter a string, which will delete a specific line in the string, which I'm unable to do it.

Text file(BookDB.txt) as shown:

Three Little Pig:Andrew Lim:89.10
All About Ubuntu:Ubuntu Team:76.00
Catch Me If You Can:Mary Ann:23.60
Happy Day:Mary Ann:12.99

Lets say I type Catch Me if You Can. It will delete the entire string line. I tried sed but kinda new to it.
This is the code I tried..

Code:

cut -d: -f1 BookDB.txt
echo "Enter title to remove"
read title
sed -e '/'$title'/d' BookDB.txt

Am I doing the correct thing?

Code:

echo "Enter title to remove"
read title
sed -i "/$title/d" BookDB.txt

Try to search "BookDB.txt" on this forum.

Haha I did try thou it only return my post and yours.

Thx dude ya awesome!!
