Passing command line argument to an Expect script

[contracer]

Hi,
Please, I need send an argument to a expect script like below:

>> ./ip_address 200.244.20.10

Where ip_address script haves an Expect script like below:

/usr/bin/expect<<EOD
log_file -noappend /tmp/sftp.log
spawn sftp sw...@200.191.200.10
expect "ip_address:"
send "ip_address\r"
expect "sftp>"
sleep 1
send "bye\r"
EOD

Let the shell expand a parameter in the here-doc...

spawn sftp sword@${1}

The sensible way to do this is like this:

#!/usr/bin/expect --

log_file -noappend /tmp/sftp.log
spawn sftp sw...@200.191.200.10
expect "ip_address:"

send "[lindex $argv 0]\r"

expect "sftp>"
sleep 1
send "bye\r"

Thanks a lot.
How could I pass a file name to the expect script ?


for FILE in `sftp_func | awk '{print $9}'`
do
/usr/bin/expect<<EOD
log_file -noappend /tmp/sftp2.log
spawn sw...@200.192.100.10
expect "sw...@200.192.100.10's password:"
sleep 1
send "alastair\r"
expect "sftp>"
sleep 1
send "cd alsat1\r"
expect "sftp>"
send "get $FILE\r"
sleep 1

Set a variable name and then use the variable with a preceding $.
Some short examples:

set arg1 [lindex $argv 0]
spawn $arg1
send -- "'$arg1'\r"

Forgot to mention those commands are in an expect script.

Could you please put these commands in the example´s script ?

Thanks a lot for your assistance.
