please scrutinize - flashcard bash script

kiloecho7 · 2008-07-07 11:50:20

Hello fellow Arch users. Today I put the finishing touches on my first attempt at a real, practical program/bash-script for myself. It seems to work perfectly fine, but I would still be obliged if you would share your wisdom, critique my code, or just plain copy it and use it for yourselves. It is essentially a bare bones flashcard program, intended to help me review my Japanese vocabulary more efficiently, drawing from a hand made dictionary file. Below is the script.

/usr/bin/flashcards:

#!/bin/bash
# flashcard program

# openning message
clear
echo "This is Matt's flashcard program."
echo "It is copyright under the GNU/GPL."
echo "Press any key to continue."
echo -n ""
read NULL
clear

DECK=$1

# identify the number of words in the deck
WORDCOUNT=$(cat $DECK | wc -l)

# start of the loop
while true ; do

# view the word
    NUMBER=$[ ( $RANDOM % $WORDCOUNT )  + 1 ]
    LINE=$(cat $DECK | head -n $NUMBER | tail -n 1)
    WORD=$(echo $LINE | cut -f 1 -d " ")
    clear
    echo "word: $WORD"

# identify how well the word is known
    READING=$(echo $LINE | cut -f 2 -d " " | cut -f 1 -d " ")
    MEANING0=$(echo $LINE | cut -f 3 -d " ")

# identify the correct answer to the multiple choice question
    OPTION=$[ ( $RANDOM % 5 )  + 1 ]
    
# check if the word is known
    echo -n "enter reading: "
    read YOMIKATA
    for X in $(seq 1 5) ; do
        if [ $X == $OPTION ] ; then
            echo "$X) $MEANING0"
        else
            NUMBERX=$[ ( $RANDOM % $WORDCOUNT )  + 1 ]
            LINEX=$(cat $DECK | head -n $NUMBERX | tail -n 1)
            MEANINGX=$(echo $LINEX | cut -f 3 -d " ")
            if [ -z "$MEANINGX" -o "$MEANINGX" == "$WORD" -o "$MEANINGX" == "$MEANING0" ] ; then
                MEANINGX="Line $NUMBER says - chicken butt!"
            fi
            echo "$X) $MEANINGX"
        fi
    done
    echo -n "select reading: "
    read ANSWER
        if [ $ANSWER == $OPTION -a $YOMIKATA == $READING ] ; then
            clear
            echo "you got it right ... RIGHT ON!!!"
            echo -n $LINE
            read NULL
        else
            clear
            echo "you got it wrong ... oh well"
            echo -n $LINE
            read NULL
            echo $LINE >> better_study.txt
            clear
            UNKNOWN=$(wc -l better_study.txt | cut -f 1 -d " ")
            if [ $UNKNOWN -gt 6 ] ; then
                mv better_study.txt better_study_$(date +%Y.%m.%d~%H.%M.%S).txt
                exit
            fi
        fi

# end of the loop
done
