4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):

AMA COMPUTER LEARNING CENTER/GENERAL SANTOS CITY/PHILIPPINES/MS. NARIN/ PRINCIPLES OF OPERATING SYSTEM (NO LINK AVAILABLE)


Note: Without school/professor/course information, you will be banned if you post here! You must complete the entire template (not just parts of it).

You're almost there... small changes:
change case 1) to:

Code:

    echo -n "Enter a word: "
    read word
    echo -n "Enter the meaning: "
    read meaning
    echo "$word means $meaning" >> word.txt
    ;;

and case 3) to:

Code:

    echo "Enter a word to delete: "
    read word
    sed -i "/$word/d"
    ;;

...and case 4) to:

Code:

    >word.txt && echo "Succesfully deleted!"

...and it should work. (works for me )
ps.
You're missing keyword esac after case 4).

weeee... Thanks for the help
Even though I already fixed my project before I read this, still I appreciate your help ^_^

Again Thank you so much... Take care and God bless you
