If this is a shell and/or expect script, why are you telling the system to use awk to interpret it???

Hi all,
I'm trying to run the sipp simulator in crontab but after some attempt I came to the conclusion that for some reason this isn't possible (maybe due to sipp interactive nature).
This is confirmed by these posts.
Now I'm trying to launch sipp from an expect script that runs in crontab.

lindex
lindex(n) Tcl Built-In Commands lindex(n)
__________________________________________________________________________________________________________________________________________________NAME
lindex - Retrieve an element from a list
SYNOPSIS
lindex list ?index...?
_________________________________________________________________DESCRIPTION
The lindex command accepts a parameter, list, which it treats as a Tcl list. It also accepts zero or more indices into the list. The
indices may be presented either consecutively on the command line, or grouped in a Tcl list and presented as a single argument.
If no indices are presented, the command takes the form:
lindex list
or
lindex list {}
In this case, the return value of lindex is simply the value of the list parameter.
When presented with a single index, the lindex command treats list as a Tcl list and returns the index'th element from it (0 refers to the
first element of the list). In extracting the element, lindex observes the same rules concerning braces and quotes and backslashes as the
Tcl command interpreter; however, variable substitution and command substitution do not occur. If index is negative or greater than or
equal to the number of elements in value, then an empty string is returned. The interpretation of each simple index value is the same as |
for the command string index, supporting simple index arithmetic and indices relative to the end of the list.
If additional index arguments are supplied, then each argument is used in turn to select an element from the previous indexing operation,
allowing the script to select elements from sublists. The command,
lindex $a 1 2 3
or
lindex $a {1 2 3}
is synonymous with
lindex [lindex [lindex $a 1] 2] 3
EXAMPLES
lindex {a b c}
-> a b c
lindex {a b c} {}
-> a b c
lindex {a b c} 0
-> a
lindex {a b c} 2
-> c
lindex {a b c} end
-> c
lindex {a b c} end-1
-> b
lindex {{a b c} {d e f} {g h i}} 2 1
-> h
lindex {{a b c} {d e f} {g h i}} {2 1}
-> h
lindex {{{a b} {c d}} {{e f} {g h}}} 1 1 0
-> g
lindex {{{a b} {c d}} {{e f} {g h}}} {1 1 0}
-> g
