AWK script replacing words in a text

[ionguang]

in a huge text
we want all of the

:tho becomes you
thou becomes you
thy becomes your
thine becomes your
and we should change Tho to You
also
the case that tho with a punctuation such tho, should be you,

basically i writer down something like this

awk '
{

for(i=1;i<=NF;i++)
{

if (($i == "thee")||($i == "thou"))
{
printf("you")
}
else if (($i == "Thee")||($i == "Thou"))
{
printf("You")
}
else
{
printf $i
}
printf " "
}
print ""
}'

There are two problems :
one is that it doesn't work fine with punctuation
second is that after the job done, it will leave a extra blank at the end of each line.

perhaps the stream editor "sed" is better suited for this

if "text" is the name of your long text, then something like this
might work:

sed 's/thee/you/;s/thou/you/;s/Thee/You/;s/Thou/you/' <text

this does what your "awk" script does
