expect script foreach loop
i´m not that familiar with expect and scripting. I try to read a hosts.txt with mutliple switchtes and interfaces inside. Then do ssh and send a few commands. I´m able to split the file in two variables: switch and interface. But how can i do a loop so that all lines were proceed? And is it possible to do the two splits in one?
#!/usr/bin/expect -f
set fp [open "hosts2.txt" r]
set content [read $fp]
close $fp
set records [split $content "n"]
lassign $records line
set oneline [split $line ","]
lassign $oneline switch interface
set password "mypassword"
spawn ssh -o StrictHostKeyChecking=no $switch
expect "Password:"
send "$passwordr"
expect {
"*#" {
send_user "nnIN PRIV MODE nn"
}
"*>" {
send_user "nnIN USER MODE nn"
send "enabler"
expect "assword:"
send "$passwordr"
expect "*#"
}
}
send "conf tn"
expect "*(config)"
send "interface $interfacen"
expect "*(config-if)"
send "shutn"
expect "*(config-if)"
send "exitr"
Here is an example of my hosts file:
switch1,GigabitEthernet1/0/1
switch2,GigabitEthernet1/0/2
switch3,GigabitEthernet1/0/3
loops expect
