i get string from a sql query, so it's in a variable: $string
i can't see carriage return any time in variable, because echo $string does no print these. and i'm not sure i'm talking about a CR.
but i'm sure something is in there, because if i try
var1='
reply'
and then i try
if [ $var1 == 'reply' ]; then
this returns false value. but again, i'm not sure if a carriage return is inside the variable.
i was trying with
${string/^M/}
but no changes.

I try to test the carriage return in a variable.
$ LENGTH=`expr $VARIABLE : ".*"` will return the length of the variable. But this doesn't work if $VARIABLE has zero length.
Any help will be well appreciated.
Thanks in advance.
