What I am trying to do is to:
.exp
file, which will read from the *.txt
file from the same directory and parse all the content in the text file into a string variable in the expect script.So what the script does, is read a series of hostname from a txt
file in the same directory, and then read them into a string, and the .exp
file will auto log into each of them and excecute a series of commands.
I have the following code written but it's not working:
#!/usr/bin/expect
set timeout 20
set user test
set password test
set fp [open ./*.txt r]
set scp [read -nonewline $fp]
close $fp
spawn ssh $user@$host
expect "password"
send "$password\r"
expect "host1"
send "$scp\r"
expect "host1"
send "exit\r"
Any help is greatly appreciated....
The code should read the contents of the two files into lists of lines, then iterate over them. It ends up like this:
# Set up various other variables here ($user, $password)
# Get the list of hosts, one per line #####
set f [open "host.txt"]
set hosts [split [read $f] "\n"]
close $f
# Get the commands to run, one per line
set f [open "commands.txt"]
set commands [split [read $f] "\n"]
close $f
# Iterate over the hosts
foreach host $hosts {
spawn ssh $user@host
expect "password:"
send "$password\r"
# Iterate over the commands
foreach cmd $commands {
expect "% "
send "$cmd\r"
}
# Tidy up
expect "% "
send "exit\r"
expect eof
close
}
You could refactor this a bit with a worker procedure or two, but that's the basic idea.
