for loop in Unix

This is the content of a file work.log
1 TGBUS I-US 0;15;83

i did this
for i in `cat work.log`
do
echo $i
done

I wanted the out put to be
1 TGBUS I-US 0;15;83

But the output appears as
1
TGBUS
I-US
0;15;83

For Loop treats space as a delimiter. Can i overrride this space as delimiter
Can anyone assist

Try this to get rid of the spaces:

Code:
while read i
do
  echo "$i"
done < work.log

This works. But theres no way to do the same with a for loop.

Just out of curiosity.

Code:
for i in "`cat work.log`"
do
echo "$i\n"
done

If i have undertood what you want, i think that:

for i in `cat work.log`
do
echo "$i \c"
done

it could be.

\c : suppress trailing newline
or
echo -n : do not output the trailing newline

I should avoid the use of cat, but if you really want to use the for loop, you can change the IFS temporary like this:

Code:
#!/bin/sh

OLDIFS="$IFS" 

IFS=""

for i in `cat work.log`;do 
  echo "$i"
done

IFS="$OLDIFS"

But ..... doesn't he want the output in a unique line ????
