Intro

TCL-Expect scripts are an amazingly easy way to script out laborious tasks in the shell when you need to be interactive with the console. Think of them as a "macro" or way to programmaticly step through a process you would run by hand. They are similar to shell scripts but utilize the .tcl extension and a different #! call.

Setup Your Script

The first step, similar to writing a bash script, is to tell the script what it's executing under. For expect we use the following:

#!/usr/bin/expect

tinti

#!/usr/bin/expect -f
set timeout 60
set host [lindex $argv 0]

stty -echo
send_user -- "Password for $host: "
expect_user -re "(.*)\n"
send_user "\n"
stty echo
set password $expect_out(1,string)

Generate private key (.key)

# Key considerations for algorithm "RSA" ≥ 2048-bit
openssl genrsa -out server.key 2048

# Key considerations for algorithm "ECDSA" ≥ secp384r1
# List ECDSA the supported curves (openssl ecparam -list_curves)
openssl ecparam -genkey -name secp384r1 -out server.key

umount: device is busy. Why?
There are several reasons why a file system cannot be unmounted. Here are a few of the reasons.

Working directory or file open of a running process

# umount /mnt/test
umount: /mnt/test: device is busy.
        (In some cases useful info about processes that use
         the device is found by lsof(8) or fuser(1))
# lsof /mnt/test/
