problem with for loop in BASH script

Question

I'm trying to execute the following loop inside my script in order to send mail to all users in a certain file that I write in earlier in the script. I check if the file $eUsers is not empty I execute the following:

for name in `cat $eUsers | cut -d' ' -f2`
do
echo "message" > /letter
cat /letter | mail -s "message" $name
done

• At the beginning of the script I define $eUsers= "/filename".
• The code : cat $eUsers | cut -d' ' -f2 gets back the user name. I tried it out in the terminal, and it's working. I tried putting the above code in a separate file and replaced "$eUsers" with its path (/filename), and it worked without any problems.

However, when I use that code in my script, after writing in the file $eUsers, it goes into an infinite loop. I dont' understand why it's doing so. In the original file, the infinite loop seems to occur because of the line cat /letter | mail -s "message" $name.

Answer 1

#!/bin/bash

while read junk name; do
  echo "message" | mail -s "message" "$name"
done < "$eUsers"
