#!/bin/bash # Um TrustBridge zu installieren: # 1. Prüfen Sie, ob Sie dieser Datei genügend vertrauen, um ihr die # Kontrolle über diesen Rechner zu übergeben. Beispielsweise # durch Vergleich mit einer starken Prüfsumme aus einer zweiten, # unabhängigen Quelle. # 2. Öffnen Sie eine Kommandozeile (Anwendung "Terminal"). # 3. Wechseln Sie in das Verzeichnis, in dem diese Datei gespeichert # ist (z.B. per Kommandozeile mit: "cd ~/Schreibtisch"). # 4. Starten Sie die Anwendung auf der Kommandozeile, beispielsweise # als Installation nur für den aktuellen Nutzer, indem Sie # eingeben: # bash TrustBridge-1.0.0-amd64.sh # Tipp: Die Tab-Taste nach dem "Tr" ergänzt oft den ganzen Namen. # # Übrigens, wir konnten kein übliches .deb-Paket verwenden, da # TrustBridge Ihnen auch die Installation als reiner Nutzer ohne # Admin-Rechte ermöglichen soll. # # # To install TrustBridge: # 1. Verify that you trust this specific file far enough, that you # are willing to hand over the control of your computer to it. For # example compare a strong checksum of the file to one from a # second, independent source. # 2. Open a command line (application "Terminal"). # 3. Change your working directory to where this file is stored. # (e.g. type "cd ~/Desktop" on your command line). # 4. Start the installation on the command line, e.g. for the current # user only by typing something like: # bash TrustBridge-1.0.0-amd64.sh # Hint: If you press the tab-key after "Tr" it may complete the # filename. # # By the way: We could not have used a .deb package, because the # installation must also work without without adminstrator # priviledges. # # # Copyright (C) 2014 # by Bundesamt für Sicherheit in der Informationstechnik (BSI). # Software engineering by Intevation GmbH. # # This file is Free Software under the GNU GPL (v>=2) # and comes with ABSOLUTELY NO WARRANTY! # For details and the license of TrustBridge # see the folder "licenses" after installation # check the corresponding revision of it online at # https://wald.intevation.org/hg/trustbridge/file/tip/licenses set -u ###INCLUDE:linux-installer-common.inc ###INCLUDE:linux-installer.l10n-de ###INCLUDE:linux-installer-uninstall.inc usage() { getxt "Usage: %s [OPTION]...\n" "$ME" getxt "Install TrustBridge.\n\n" getxt "Options:\n" getxt " -p, --prefix=PATH install files in PATH\n" getxt " -f, --force install to given prefix, even when a current\n" getxt " installation with different prefix exists.\n" getxt " -u, --uninstall uninstall files from current installation\n" getxt " -s, --system create a system wide (de)installation\n" getxt " --help display this help and exit\n" getxt " --version output version information and exit\n" exit $1 } parse_args() { OPTS=`getopt \ -l uninstall,update,force,help,prefix:,system,version \ -o d,f,p:,s -n "$ME" -- "$@"` [ $? -eq 0 ] || usage 23 eval set -- "$OPTS" while true ; do case "$1" in --prefix|-p) instcfg[PREFIX]="$2" shift 2 ;; --system|-s) SYSINST=1 shift 1 ;; --force|-f) FORCE=1 shift 1 ;; --uninstall|-u) DEINSTALL=1 shift 1 ;; --update) # Update is an internal option that is used when the application calls # the installer to install an update.
