Syntax help with unzip on 7z please.
« Thread Started on Jan 6, 2012, 12:25pm »

I'm trying to do a script to unzip a folder when a CD first boots ::)

Quote:

#!/bin/sh
unzip -f /home/user/ukbrian.zip

I've tried -x but no luck and manuals don't speak my language

I would much prefer to use .7z files as they get much, much greater compression than anything else I know of.

Edit
Is there any folder to put the script so it runs earlier than the ~/.config/autostart dir

What are you trying to do exactly? You run unzip only with path to file to extract it.

Code:
unzip /pathto/yourfile.zip

I'm not succeeding and I've decided the best thing to do
is make a short video of what i'm trying to do and that will be a lot
more informative than me typing words.

Thank you for trying to help a 69 year old who spent his
working life in the building trade as a roofing contractor.

if you have p7zip installed,

Code:
$ 7z -f /home/user/ukbrian.zip

should unzip ukbrian.zip

[-e without paths, -f with paths]

We didn't have computers in school.
Didn't know what computers were.
Is that why this is more fun today?

How about a right click on ukbrian.zip, then, Extract here or to: Does that give you a choice?

I've made a video but unfortunately it ended up 10 minutes long at 199 MB but 7zip got that down to 40 MB.

I get a bit lost sometimes but I think I covered everything, just a bit tired at the moment.
http://lin.me.uk/help/problem-01.mp4.7z

I'm wondering if it's possible to zip up other parts of the OS to reduce the CD size and then unpack when the OS boots, maybe I'm crazy.

Everything I do i expect is very crude but if anyone knows a more elegant way please feel free.

It's 2 in the morning so i might go to bed soon
once again thank you for helping an old fool.

Doing it after X starts wouldn't be too hard, just create a script and tell Xfce to run it Xfce4 Settings Manager > Sessions and Startup > Application Autostart. For the command on the autostart I would do this:

gksu "exec /usr/bin/xfce4-terminal -H -x /path/to/script/script-name" (Leave gksu off if you don't need root)

You can follow this guide somewhat http://www.debian-administration.org/articles/28 Keep in mind there would be more bash scripting involved.

@UKBrian,
Maybe cfdisk, the CLI partition manger might do better for this?
GUI things don't always lend themselves to non-interactive operations.

It's perfectly reasonable, there are CD filesystems, that exactly do that. Knoppix is working this way, it uses squashfs (at least it used when I last checked, but that was quite time ago). Is this thread connected with qt-fsarchiver? Maybe after watching your video my mind will become more clear

Sorry, I got side tracked, to clarify.
Problem 1
I think qt4-restore CD does all that is required of it. The only thing I'd like to change is the hard coding in the /home/user/xfce-menus/desktop.menu file which doesn't matter in the CD as it's not for installing.
Quote:

<AppDir>/home/user/xfce-menus/applications/</AppDir>
<DefaultDirectoryDirs/>
<DefaultMergeDirs/>

If the red text could be replaced with "~/" or "$HOME" or some alias it would mean that any end user unzipping the xfce-menus folder into their user folder and then creating a new menu launcher in their panel could point at the "/home/user/xfce-menus/desktop.menu" file and would then have my custom menu on their panel. I'm trying to make these menus portable I guess.

If this can be achieved with the .menu file then the same method can be used in the .desktop files to point at their icons.

Problem 2 is the unzip business which isn't urgent as the qt4-fsarchiver already fits on a CD

I think the qt4-fsarchiver iso you downloaded was 705 MB when remastersys'ed but I tried another snapshot script and that got the snapshot down to 647 MB so I removed midori and put firefox on instead but with firefox and a firefox profile the size went up to 714 MB. :'(

I put the firefox app and profile in the folder "ukbrian" and when I zipped up the folder before doing a snapshot I got the size back down to 700 MB.

hence my interest in
unzipping the folder on the fly while the system boots

I've been playing with another menuing approach as well and it just amazes me why mozilla don't use it for their default firefox profile.

If you want a bit of fun for a moment, maybe Anthony will smile again, Sorry the profile is not quite right, I'll redo the link when i've uploaded a new profile
download and unzip this folder "ukbrian" into your home

Create a profile in firefox/iceweasel with
Quote:

firefox -P

and point it at
Quote:

/home/user/ukbrian/firefox/profiles/menus

If you don't have firefox or iceweasel on your machine there's a copy of firefox in the firefox dir
Quote:

/home/user/ukbrian/firefox

I'm using Josep Del Rio's Speed Dial extension to create a menuing system that I think has promse. :-X

There is no other Speed Dial version that comes anywhere near what Josep has done.

I've got into a long rambling post again, I'd better go and hide

In quote you're writing about /home/user/xfce-menus but you don't have /home/user/xfce-menus nor /home/user/ukbrian/xfce-menus in your system, maybe that's a reason?

To unzip you must have exec before unzip and -f is not needed

Code:
#!/bin/sh
exec unzip /home/user/ukbrian.zip

It will be good to tell unzip where to unzip files, independent from where it was started, with option, example: unzip /home/user/ukbrian.zip -d $HOME/xfce-menus otherwise everything will be in vain, if user extracted somewhere else than you expected. And first check if user have unzip, if not use other program, and if failed to find any be verbose that it can't be extracted and about lack of needed program. Let the fun be with you!

and -v mode is better to resolve problems than hiding

That exec did it now I can unzip them on boot up. thank you petrik

That was a good link Anthony but a bit above my abilities.
I put the unzip script in /etc/init.d and then did this and got an error
Quote:

root@saline:~# chmod 755 /etc/init.d/unzip-ukbrian.sh
root@saline:~# update-rc.d unzip-ukbrian.sh defaults
update-rc.d: using dependency based boot sequencing
insserv: warning: script 'unzip-ukbrian.sh' missing LSB tags and overrides
root@saline:~#

But no hurry I think I need a break for a bit. :-*

You need to put more things to that script, I think. And create proper symbolic link for yourself, only in one runlevel. Also, I would add some things to that script to go around this /home/user issue in the menu. You can do that in two ways, install it somewhere else, not in home directory, or change the files after unzip to contain the proper path.

I have .zip files unzipping now thanks to petrik but no luck with the .7z files.
I've tried

Code:
7z /home/user/ukbrian.7z
exec 7z /home/user/ukbrian.7z
exec $ 7z /home/user/ukbrian.7z

[/code]all good fun but without success

I started in the dos days so I've watched the OS's evolve but very little has been done with the desktop, it's just been used for graffitti or decorations so I think shell and unity might well develop into something worth while, I think the tree menu will always be there but not for most users.

I'm going on again :-[
