set output of linux cmd as a variable in .exp

I am trying to make a script to take commands from a .txt file ( line by line) and pass it using send ( used in another function )

what i am trying to achieve is :
set nol "`grep '' ${exp_path2}/cmdlist.txt | wc -l `"

as in shell script
nol=`grep '' $exp_path2/cmdlist.txt | wc -l`

for {set i 1} {$i < $nol} {incr i 1} {
 set cmds "`grep '' ${exp_path2}/cmdlist.txt | sed -n ${i} p`"
 myPuts $cmds
 runSilentCmd $tid "${cmds}"

But, obviously I am doing something wrong. I don't know if it's just syntax error or its simply not possible to use unix cmds like this inside a .exp script.

Kindly help.
