Shell Programming and Scripting

dont have it available. Maybe tomorrow.

due to restrictions i can't post my script. However, I will give a watered down version
____________________________________________________________
cat t1 | while read a b c d #t1 is the file a,b,c,d are the columns
do
cat << EOF

echo "$b" #shows what it should
echo "$c" #shows what it should

var1="$b"
var2="$c"

echo "var2" #this is returning echo ""

echo "var2" #this is returning echo ""

EOF
break
done
__________________________________________
Does it have something to do with using "read"?

If your script is pasted correctly, then there's a space after the closing EOF that is breaking it.

As for var1 and var2, you are inside a cat here, so all you're doing is printing
var1="$b"
var2="$c"

You should assign them before the "CAT << EOF"

The echoes of the two var variables weren't correct, I also did the following:

Code:

$ cat ./simpleaasign.sh
#!/bin/bash
while read a b c d
do 

  echo "$b"
  echo "$c"

  var1="$b"
  var2="$c"

  echo "$var1"

  echo "$var2"

done < tl
$ cat tl
aa bb cc dd ee ff
aaa bbb ccc ddd eee fff
aa1 bb1 cc1 dd1 ee1 ff1
aa2 bb2 cc2 dd2 ee2 ff2
aa3 bb3 cc3 dd3 ee3 ff3
$ ./simpleaasign.sh
bb
