Reading file and assigning that to Variable

I am missing something here, I have a file which contains only one line and that is either a number or character string. I am trying to read the file and assign that value to a variable and here it seems I am missing something and not getting the expected results... Here is the code :

#!/bin/ksh

cat dbsnap2.txt | grep 'Rows selected' | cut -c 46-60 > Rows_selected.tmp
cat Rows_selected.tmp
rows=`echo "Rows_selected.tmp"`
echo "Rows selected are ............" rows

Output coming out is
--------------------
128622023
Rows selected are ............ rows


Output expected is
--------------------
128622023
Rows selected are ............ 128622023

Appreciate your help. Let me know if you need more info.

NAME
times - shell built-in function to report time usages of the current shell SYNOPSIS
sh times ksh times DESCRIPTION
sh Print the accumulated user and system times for processes run from the shell. ksh Print the accumulated user and system times for the shell and for processes run from the shell. On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways: 1. Variable assignment lists preceding the command remain in effect when the command completes. 2. I/O redirections are processed after variable assignments. 3. Errors cause a script that contains them to abort. 4. Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name genera- tion are not performed. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
