Escape space in for loop
I have a file with the following contents

Code:
[root@rf4003 scripts]# more hello.txt
man
hello man
whereru

The shell script i have tries to echo the contents of the file hello.txt
Code:
for i in `cat hello.txt`
do
        echo $i
done

but the output i am getting is taking the space as a new line..
Code:
[root@rf4003 scripts]# ./hello.sh
man
hello
man
whereru

Can anybody help me to echo the contents of the file
as it should be?

The use of cat is redundant (UUC), use a while loop and quote the variables:

Code:
while read i
do
  echo "$i"
done < hello.txt

Code:
cat hello.txt | while read i
do
  echo "$i"
done

This is also working.. thanks Franklin

As mentioned, the use of cat is redundant and cost an extra process. Have a read of Useless Use of Cat Award.
