Put them in a condition thats never true.
Code:
if [ 1 == 0 ];then
script.sh
 rm text
 for i in * 
do
.
.
.
.
 .
done
fi
if [x = y] 
then
 rm

Put comment signs in front of the lines:
Code:
# rm text
# for i in *
# do 
# .
# .
# .
# .
# done
# .
if [x = y]
then 
rm

If you dont want to comment it out, then you can use the "if" condition.

Well, if you use vi you can use:
Code:
:1,/if \[x = y\]/s/^/# /

And then delete the last comment...

[..]

The correct syntax is
Code:
if [ 1 = 0 ]; then

But you could also use:
Code:
if [ ]; then

or
Code:
if false; then

If your shell allows for here documents, you could try
Code:
script.sh
<<EOF
rm text
for i in *
do
.
.
.
.
.
EOF
if [x = y] then  rm

Make sure that the token (here:EOF) does not occur anywhere in the portion to be skipped.
