hi

my brain is not working too well.

I have a script that downloads a file and then next command works ok...inside that script

:: Code ::

chmod +x unpack.sh

but then as a local user I want to make it root owned so I tried

:: Code ::

chown root:root unpack.sh

but it is not working for me.


Any help will be appreciated.

2) I can always ask the user to open a root shell and do it by command but I am trying to reduce the commands they issue to 3 scripts....a download script....an unpack script and a repack script.

the download script they need to manually download and it downloads the other scripts and other files.

regards

gordy

local user can't make the file root owned, root is larger than local user, and local user is a subset of root.

When I want to make a file root owned, this is how I do it:

when I create the file, locally: chown root:root filename
then: zip filename.zip (zip file name) [list of files to zip: filename]

example:
chown root:root unpack.sh
zip unpack.zip unpack.sh

Then user downloads unpack.zip, unzips it:
unzip unpack.zip
and there is root owned unpack.sh

hi

EDIT
thanks will do....and the zip will work nicely as the last 2 scripts will be root owned.

Now that I am going to be smarter and use a zip....all non-Tinycore binaries and iso will now be in the zip.

The unzipped download.sh will then be used to download:
the tinycore iso and some tinycore binaries.

I will now append to my grub2 random thoughts

thanks heaps

hi

OK getting around to small test of root powers for zip.

only used 3 files for this test

:: Code ::

su
chown root:root script2.sh script3.sh
chmod 700 script2.sh script3.sh

 zip test.zip script*
  adding: script1.sh (deflated 76%)
  adding: script2.sh (deflated 60%)
  adding: script3.sh (deflated 48%)
  adding: test.zip (stored 0%)


so far so good....3 files in zip

file manager shows zip is owned by root

2) copy zip file to another folder and unzip it

:: Code ::

su gordy
mkdir test/
cp test.zip test
cd test/
unzip test.zip
ls -al

-rwxr--r--  1 gordy gordy 3241 Mar 21 19:46 script1.sh
-rwx------  1 gordy gordy 3643 Mar 22 08:41 script2.sh
-rwx------  1 gordy gordy 1071 Mar 21 19:37 script3.sh

-rw-r--r--  1 gordy gordy 6646 Mar 22 16:54 test.zip



I did this twice actually as I did not watch my output close enough and wanted to be sure

looks like you're right, I faintly remember that this used to preserve file ownership, but it doesn't seem to be doing that now.

hi

no worries...I have taken some stuff and modded it from a script from Slitaz...GPL2

so that start of those scripts are

# before anything test we are root

if test $(id -u) != 0 ;
then echo "you need to be root"
exit 0
fi


eg
:: Code ::

gordy@sid:~$ ./script2.sh
you need to be root
gordy@sid:~$

oh, you just wanted to check for root? you should have asked me, of course, that's a trivial test, all the xi scripts check for root for various reasons, I was wondering why you were wanting root ownership but didn't really give it much thought.

:: Code ::
if [ "$(whoami)" != "root" ];then
   error_handler 'not-root' $FUNCNAME
fi

hi

1) could not get your thing to work as I have not defined it so modded it to

:: Code ::

if test $(whoami) != 0 ;
then echo "you need to be root"
exit 0
fi


2) No sorry....back to square one....I needed zip to maintain root permissions but it does not.

So now.....I need a test for scripts 2 & 3 because they need to be run as root.

So I now modded script1 to tell the USER to make them root...in a echo in case they can't read my simple scripts

3) Anything too technical goes over my head as I am still not a script guy but greatly appreciate your efforts


PS if I seem a little abrupt its because I have to find a new file sharing free site....stashbox seems to baulk at my over 40 meg upload of my iso.

grrrrr

No I am not going to pay money.
No I am not going to Mediafire who blast users with so many freaking ads the user is likely to leave pronto.

If anyone cares to suggest a good site for iso uploads feel free to suggest please

regards

I hate those test... statements, and refuse to use them, along with many other horrible bashisms, they are non-standard programming syntax and almost impossible to read or debug.
