Full Discussion: EXPECT: Assign variable by reading a line of text from a file

Expect is for interactive keyboard driven tools with no batch or script-friendly command line mode. If you make an expect script that works with one mac address, you could write a normal bash/ksh script to read the mac addresses, gen an expect script with that mac address embedded and run it. Expect is written in tk/tcl, as I recall, so you need skills in that arcane area to vary the script dynamically. I mostly write my expect scripts using autoexpect, or fake it using shell scripts reading the output file to determine progress. Are you going to windows autokey using telnet?

viewsu

VIEW-OS(1)						      General Commands Manual							VIEW-OS(1)

NAME

       viewsu - change (virtual) user ID or become (virtual) superuser

SYNOPSIS

       viewsu [options] [username]

DESCRIPTION

       The viewsu command is used to become another user during a login session. Invoked without a username, viewsu defaults to becoming the supe-
       ruser. The optional argument - may be used to provide an environment similar to what the user would expect had the user logged in directly.
       This  command  is  the  View-OS	counterpart  of  the  su(1)  command.	The  value of $PATH is reset to /bin:/usr/bin for normal users, or
       /sbin:/bin:/usr/sbin:/usr/bin for the superuser. This may be changed with the ENV_PATH and ENV_SUPATH definitions in /etc/login.defs.

OPTIONS

       The options which apply to the viewsu command are:

       -c, --command COMMAND
	   Specify a command that will be invoked by the shell using its -c.

       -, -l, --login
	   Provide an environment similar to what the user would expect had the user logged in directly.

	   When - is used, it must be specified as the last viewsu option. The other forms (-l and --login) do not have this restriction.

       -s, --shell SHELL
	   The shell that will be invoked.

	   The invoked shell is chosen from (highest priority first):

	   o   The shell specified with --shell.

	   o   The shell indicated in the /etc/passwd entry for the target user.

	   o	/bin/sh if a shell could not be found by any above method.
