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.

NAME

       el -- program to make a tuned shell-command for Oneliner

SYNOPSIS

       el  [-acdfhioxV]   [--command cmd]  [--args n]  [--format fmt]  [--execute]  [--inpipe buf]  [--outpipe buf]  [--serial]  [--help]  [--ver-
       sion]  [--debug]

DESCRIPTION

       This manual page documents briefly the el command.

       This manual page was written for the Debian distribution because the original program does not have a manual page.  Instead, it	has  docu-
       mentation in the GNU	  Info format; see below.

       el  is  a program that You can make a tuned shell-command for Oneliner with.  This command can send S-exp to Emacs, and this can make Emacs
       evaluate it, too.  In other words, you can execute Emacs's function from shell-commands.  And you can make Emacs work in closer cooperation
       with your favorite shell-commands.

OPTIONS

       These  programs	follow	the  usual  GNU  command  line	syntax, with long options starting with two dashes (`-').  A summary of options is
       included below.	For a complete description, see the Info files.

       -c cmd		--command cmd
		 cmd means a function of Elisp.  Command line arguments and data from stdin means arguments of cmd.  If you specify  the  only	-c

		 Specifies the maximum number of arguments of a Elisp function with -c switch.

       -f fmt		--format fmt
		 Allows you to use format string of printf for making a S-exp.

       -x	    --execute
		 Requests to Oneliner to evaluate the S-exp to use *Oneliner auto-eval* buffer.

       -i buf		--inpipe buf
		 Gets input from pipe-buffer. You can specify a number of pipe-buffer, too.

       -o buf		--outpipe buf
		 Puts output to pipe-buffer. You can specify a number of pipe-buffer, too.

       -s	    --serial
		 Makes el to serialize multiple lines to one line.

       -h	    --help
		 Display help message.

       -V	    --version
		 Display version identifiers.

       -d	    --debug
		 Enable debugging state.

SEE ALSO

       The programs are documented fully by Oneliner(Shell-mode hooks for Oneliners)	   available via the Info system.
