Bash backup script | Eyecandy > Dialog/ncurses script

0devnull0 · 2016-08-30 07:47:04

Hello community,
I was using Archlinux since few months and I was able to figure out most of the issues alone or/and by web searching, but now I need your help, so this is my first thread ;-)
Am trying to transform a simple bash script to a dialog/ncurses script to no avail. The main reason why I want to use dialog is -apart from the visual effect- the possibility to use different paths (source/destination), while this wont be possible with the simple script. My scripting skills are quite 'primitive'.

#!/bin/bash
##
## Rsync System Backup And Restore
## A try to implement an ncurses UI with dialog... Still not working... :(

#Set parameters
which dialog &> /dev/null
[ $? -ne 0 ]  && echo "Install Dialog pkg to proceed!" && exit 1
which rsync &> /dev/null
[ $? -ne 0 ]  && echo "Install rsync pkg to proceed!" && exit 1

May be someone find it useful and want to use it too, at least the working part, so feel free to do whatever you like with it

That manjaro section is written by someone with zero understanding of the Bash language. Using break statements with "case" is a dead giveaway. Don't base your script on it.

Anyway you can put it through shellcheck:

http://www.shellcheck.net/

Or better, outline what exactly you're trying to achieve.

Thanks Alad, the links were very helpful especially shellcheck.
What I want to do is to be able to choose what to backup and where to save the backup (locally). That was actually the problem, because I don't know
how to save source/destination and other variables to temporal files and use them later in the script...
This is what I come up with, am quite happy with it, the only problem (up till now) is when the dialog opens I select an item and hit enter, only the previous path
I set in the script is actually saved to the "tmpfile" not what I select. Example:

dialog --title "source" --dselect /home/ 10 15 2>"/tmp/UserDir_$(date +%d.%m.%Y)"

It shows on the top '.' '..' and 'myusername'. I select then my username and hit enter, but what is saved is /home/ not /home/myusername.

#!/bin/env bash
