How can I run a script as root at startup ?

[oasipet]

Hi,

I have installed a binary distribution of ROOT (using root privileges).

I need to put the script

Code: Select all

source <dir-where-you-installed-root>/bin/thisroot.sh

near the end of the ~/.bash_profile (or ~/.login for csh/tcsh)
(see: https://redmine.jlab.org/projects/podd/ ... stallation),
to set up it.

In Mint Una, which file is to consider ? (root privileges are required)

Thanks in advance,
best regards

Nowhere in the linked page do the instructions say you should run this script as root. Are you sure you need to do that? Where does it say that. Red flags if it needs that for a shell script! Find an alternative way to install it that doesn't require you to run the shell script as root on start up.

On Linux Mint you have a ~/.profile file. Add the line (with the correct path) in that. This executes it as your user on log in.

Referring to https://redmine.jlab.org/projects/podd/ ... stribution
to configure the environment:

Code: Select all

# source ~/Apps/root/bin/thisroot.sh

works...

but I need root permissions, infact:

Code: Select all

$ source ~/Apps/root/bin/thisroot.sh
bash: /root/bin/thisroot.sh: File or directory does not exist

Instead if directory "root" is in the current user's home folder

Code: Select all

$ chmod 777 ~/root

Code: Select all

$ source ~/root/bin/thisroot.sh

works...

If I put near the end of the ~/.profile the above code:

Code: Select all

source ~/root/bin/thisroot.sh

it doesn't work.

Let's go back to the beginning; how did you install ROOT? From the Ubuntu binary packages? Or did you build it from source. Either way, I don't see it requiring you to install this software in the home directory of the administrator user (directory /root). You can put the files in whichever directory you want. And then you use:
source <the directory where you extracted the .tar.gz>/root/bin/thisroot.sh

So if you extracted it in a directory called Apps in your own home directory /home/oasipet/ you would do:
source /home/oasipet/Apps/root/bin/thisroot.sh

If you put it in a system-wide directory /apps that you made, you would do:
source /apps/root/bin/thisroot.sh

As a regular user you are not permitted to access the administrator user's home directory, and you should not need to. Simply extract the .tar.gz in a more appropriate place.

Code: Select all

$ chmod 777 ~/root

Code: Select all

source ~/root/bin/thisroot.sh

The .profile file gets loaded when you log in. Did you log out / reboot after making the change to .profile?

Others, do you perhaps also have a .bash_profile file in your home directory? Then the .profile file doesn't get loaded, unless the .bash_profile file does that.

source is not POSIX and I upon reading assumed it would be a matter of /bin/sh (dash) rejecting it, but ~/.profile is explicitly sourced by in our case /usr/sbin/lightdm-session which is in fact a /bin/bash script and not a /bin/sh one so that didn't pan out.

Still posted, so you/he don't have to check, but also to say to poster that it's still a bit better to in a file such as ~/.profile use old-style . rather than "new-style" source so as to not have to know the above.
