Bash Script Help

#!/usr/bin/expect --

# ftp-rfc <rfc-number>
# ftp-rfc -index

# retrieves an rfc (or the index) from uunet

exp_version -exit 5.0

if {$argc!=2} {
        send_user "usage: this_script <ip_address> <packeteer_ip>\n"
        exit
}

send_user "$argv"


send_user "\n"
exit

Is my script. I copy-pasted most of it and I guess its finally stuck on me. This is my problem;

I used to do $1 to get the first parameter, $2 the second and so forth and so on. For this one, I am stuck on doing the same. I am trying an expect script here and not /usr/bin/sh


Any help?

You have to learn how to program using Tcl which expect is based upon:

Here is your script:

#!/usr/bin/expect --

# ftp-rfc <rfc-number>
# ftp-rfc -index

# retrieves an rfc (or the index) from uunet

exp_version -exit 5.0

if {$argc!=2} {
send_user "usage: $argv0 <ip_address> <packeteer_ip>\n"
exit
}

for { set i 0 } { $i < $argc} { incr i } {
puts "[lindex $argv $i]"
}

send_user "\n"
exit

Here is what it produces:
[philippe@victor script]$ ./expect.sh 127.0.0.1 telnet
127.0.0.1
telnet

OK, I see that

for { set i 0 } { $i < $argc} { incr i } {
puts "[lindex $argv $i]"
}

is the main function here.

Trying to do

send_user lindex $argv $1

(to get the first variable), the shell complains that

can't read "1": no such variable
while executing
"send_user lindex $argv $1"
(file "./telnetSession" line 19)

Way forward?

exit
}

for { set i 0 } { $i < $argc} { incr i } {
puts "[lindex $argv $i]"
}

send_user "[lindex $argv 1]\n"
exit

[philippe@victor script]$ ./expect.sh 127.0.0.1 telnet
127.0.0.1
telnet

Thanks

[lindex $argv 0], [lindex $argv 1], ..., [lindex $argv n]

is exactly what I needed
