im trying to read from a file line by line using a 'for' loop is it possible in bash?

2

yes it is!

3

how do i do it?
can you help me

i have tried
for i in $(cat $file)
do
echo $i
done

its output is word by word by wanted to read the whole line

4

something like:

for i in `cat /path/to/file`
do
your code here
done
5

Try seeting IFS to some character which is not in the file you which to read i.e.

IFS=:
for i in $(cat $tmp)
do
   echo $i
done

It is an IFS issue, which default can vary from shell to shell (sh, bash, ksh ...) if I remember correctly.
Actually, DukeNuke2's code is the same as the original one. Try this:

IFS=$'\n'
for i in $(cat $file)
do
   echo "$i"
done

Why don't you use a while loop?

use a while loop like radoulov says. Its also meant for reading files in bash, without using cat

while IFS= read -r line
do
 ....
done < "file"
