EDIT:
tested it with this script:

#!/bin/sh
whoami > whoami.txt

works :)
Hmm, i am also having a similiar problem,
I tried
Code:
sudo /usr/bin/run-standalone.sh /opt/script.sh
but i am getting error:
Code:
standalone.sh: line 11: /opt/script.sh:permission denied.
Please help

So do i make it so that sudo chmod +x script.sh is done automatically after install? I am trying to make a deb package

as root

chown root YOURFILE
chmod 4775 YOURFILE

voila!

Yes, but these commands have to be performed by the users right?

What I want is, after instaling the deb file, the users should be able to start the app normally but it should have root priviledges. For refrerence, this are the scripts that I am planning to make into a package.
So, while creating the deb file, in the .desktop file, for exec=, what command should I give? Right now i tried with
Code:
sudo run-stanalone.sh /opt/script.sh
But no luck.

Am I doing something glaringly obvious and dumb here?

Re: How to use root within script/program?
 
OK, i have finally figured out how to run some of scripts as root, when started by user.
I have a bunch of 5 scripts, with a main script acting as the menu or gateway. The main script is launched normally via an icon as
Code:
sh parentscript.sh
in that script, it calls the other scripts as
Code:
sudo run-standalone.sh sh childscript1.sh
This methodology seems to be working for me. But one the users of this app is having a problem that xterm is asking for password on execution of sudo run-standalon.sh.

Can anybody help us?

There's another method that works great which I saw based on this:

http://talk.maemo.org/showpost.php?p...1&postcount=16

From the above link (disable_ts.zip)

If you put this in a script file:
Code:
sh -c 'echo "sleep 1; echo 1 > /sys/devices/platform/omap2_mcspi.1/spi1.0/disable_ts" | sudo gainroot'
echo 1 > /sys/devices/platform/omap2_mcspi.1/spi1.0/disable_ts should fail as permission denied if executed as normal user since it is modifying a sysfs file. But the above method of piping to sudo gainroot works!

Hey thanks a lot! piping the command to sudo gainroot works like a charm!

yes in your postinstall script

Setting permissions in the postinst is a band-aid. The correct permissions should already have been in the packed deb, i.e. the permissions should preferably be set in debian/rules or other makefile/buildscript, not in the package postinst.
