try this: make an input.txt with \\\[ and run this script. it expects an argument which it uses for "expect". it then prints the argument, global $myexp and the line read from the file in da.log.

you can take out the send/expect part.


#!/usr/bin/expect -f
#
set logfile [open "da.log" w]
set myarg [lindex $argv 0]

set myexp "\\\["

set filename "input.txt"

set input [open $filename "r"]

gets $input line
puts $logfile "from file: = $line"
close $input

proc do_it { exp } {

global logfile

puts $logfile "do_it: expecting $exp"
send -- "ls\r"
expect {
timeout { puts "timed out!!" }
$exp
}
}


puts $logfile "myexp:$myexp and argument:$myarg"
set timeout 5

spawn $env(SHELL)
match_max 100000

do_it $myarg

logsave

LOGSAVE(8)						      System Manager's Manual							LOGSAVE(8)

NAME

       logsave - save the output of a command in a logfile

SYNOPSIS

       logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION

       The  logsave  program  will  execute  cmd_prog with the specified argument(s), and save a copy of its output to logfile.  If the containing
       directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out.	A copy of the output  will
       also be written to standard output.

       If  cmd_prog  is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
       logfile

       logsave is useful for saving the output of initial boot scripts until the /var partition is mounted,  so  the  output  can  be  written	to
       /var/log.

OPTIONS

       -a     This option will cause the output to be appended to logfile, instead of replacing its current contents.

       -s     This  option  will  cause  logsave  to  skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
	      Header) and control-B (ASCII 002 or Start of Text).  This allows progress bar information to be visible to the user on the  console,
	      while not being written to the log file.

       -v     This option will make logsave to be more verbose in its output to the user.
