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 :
Code:
set nol "`grep '' ${exp_path2}/cmdlist.txt | wc -l `"

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

and
Code:
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.

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
