Frage an die shell programmieren können

Hey Leute ich brauche mal eure Hilfe und zwar bin ich dabei bei mir vpn einzurichten nun wollte ich eine cascarde einrichten heißt 3 vpn verbindungen hinter einander schalten und dachte mir dabei bevor ich den ganze kram alles immer ein tippen muss oder copy/paste bau ich nen script alles so gut soweit nun habe ich den script
soweit fertig tut auch das was er soll nur jetzt habe ich das problem das openvpn am ende ein selbst generierten weiteren befehl schreibt den ich copy/paste ins neue terminal fenster eintragen muss

nun zu meine frage gib es die möglichkeit ihrgend wie das was er ausgibt in eine txt zuspeichern und dann von nen script weiter geben zu lassen in ein neues terminal ???


http://ift.tt/1oOEBLo
so sieht das ganze aus es geht um die zeile --setenv hopid 2 --setenv prevgw 10.1.13.1 die wird generiert vom uphop.sh script und die möchte ich gern im neuen terminal übergeben


Der uphop.sh script sieht wie folgt aus

Zitat:

---

#!/bin/bash
#
# This script can be used as an up and down script for OpenVPN.
# It adds and removes the routes required for a VPN connection cascaded over
# multiple vpn servers provided by Perfect Privacy.
#
# Usage:
# Start OpenVPN with the following options:
#
# openvpn
# --config <config file>
# --script-security 2
# --route remote_host
# --persist-tun
# --up updown.sh
# --down updown.sh
# --route-noexec
# --setenv hopid <hop number>
# --setenv prevgw <gateway>
#
# config file
# The *.ovpn config file, ie. "London.ovpn".
# hop number
# The number of the hop in the cascading chain, starting with 1.
# For the first hop, you can omit the hop number (default: 1).
# It is limited to 5, to limit the amount of total routes.
# gateway
# The gateway (internal server IP) of the previous hop as provided
# in the log of the previous hop.
# For the first hop ('hop number' = 1), you can omit the gateway.
# In that case, the gateway of your local network will be used.
#
# TL;DR: Just start openvpn with all parameters listed above except the last
# two (--setenv). You will find the command line for the next hop in the log,
# you will just need to change <config.ovpn> for the configuration file of
# the server of your choice.
#
# Example:
# Hop #1:
# sudo openvpn --config London.ovpn --script-security 2 --route remote_host
# --persist-tun --up updown.sh --down updown.sh --route-noexec
#
# Hop #2 (copy-paste this command line from the log of the hop #1):
# sudo openvpn --config Rotterdam.ovpn --script-security 2 --route remote_host
# --persist-tun --up updown.sh --down updown.sh --route-noexec
# --setenv hopid 2 --setenv prevgw 10.1.13.1
#
# Hop #3 (copy-paste from hop #2):
# sudo openvpn --config Reykjavik.ovpn --script-security 2 --route remote_host
# --persist-tun --up updown.sh --down updown.sh --route-noexec
# --setenv hopid 3 --setenv prevgw 10.18.12.1
#
# NOTE:
# We recommend using a dedicated terminal window for each hop. That way the log
# outputs for each hop can be easily kept apart. It also guarantees that the
# routes can be added and removed again in the right order.
#
# Advanced Options:
# --setenv disable_resolvconf 1
# By default, this script executes '/etc/openvpn/update-resolv-conf'
# to update your DNS settings. You can disable this behaviour by
# setting the environment variable 'disable_resolvconf'.
