Full Discussion: Shell script use two variable in for loop

The 'while read' loop is better in almost every way. It avoids the waste of using cat, and doesn't have the unfortunate side-effects of working behind a pipe (variable changes not preserved in most shells).

Code:
while read USERNAME COMMENT
do
        echo "USERNAME=$USERNAME, comment=$COMMENT"
done < inputfile

You can change the delimiter by changing the IFS variable, i.e. IFS=":" read var1 var2 var3
