Problem with echo and cut

Hi,
My source file happens to be src.src with following contents:
Code:
1,liv 52,syrup,twice a day,children

When I do a :
Code:
 
for ii in `cat src.src`
do
echo $ii
medicine_name=`echo $ii | cut -f -d2","`
echo $medicine_name
done

I get output of
Code:
echo $medicine_name

as :
Quote:
52,syrup,twice
an the output of

Code:
echo $ii

is :

Code:
1,liv
52,syrup,twice
a
day,children

Please guide me in fixing the line breaks.

That for loop with cat is not recommended

You should use a while loop instead, try something like:
Code:
#!/bin/bash

while IFS="," read v1 v2 v3 v4 v5
do
        printf "%s\n" "$v2"
        printf "%s,%s,%s,%s,%s\n" "$v1" "$v2" "$v3" "$v4" "$v5"
done < src.src

Yoda is right, there are better ways to achieve what you want, but setting IFS to "," and getting the cut command right will make your code snippet fly.
