I'm working on a Linux Bash script that needs to start as root. At the end of the script, it builds a list of packages. This requires running as user. Then it will move the packages, which needs to run as root again. I have sudo set up, but want to keep the script as generic as possible.
I've tried the following and slight variations of it in the first script to switch from root to user.
su -c - "$USER" "export PKGDEST=/tmp/test/AUR/"
su -c - "$USER" "pacaur --noconfirm --noedit -cm" "$(< /tmp/test/aur)"
The second line fails to run properly resulting in different errors, depending quote combination and placement. Running the lines within the first script as shown above produced the following error after reading the file /tmp/test/aur :: no targets specified (use -h for help). My preference would be getting this single script method to work properly.
Google, etc. said root, user, root in bash is bad, so tried break it into 3 parts:
- The first script runs as root. The problem centers here, can't get
it to start the second. - Second script runs as user, starts 3rd script as root with: sudo
/bin/bash "$L"/copyaur.sh - Third script, copyaur.sh runs, moving the packages properly but
doesn't show as running in the terminal because calls new shell?
Below was ran as su in a user terminal during testing. Prefer using the $USER var in the script.
As su in the terminal, then back to su - $USER, then ls in home lists my normal user name [dom's] contents.
[dom@arch testing]$ echo $USER
dom
[root@arch testing]# echo $USER
dom
[root@arch testing]# pwd
/home/dom/scripts/testing
I get the following results in testing, starting as su in the terminal. Want to get $USER var to work in place of dom.

su --login $USER home/$USER/scripts/testing/buildaur.sh - No such file or directory

Here's part of the script. Still no solution. This latest variation has made it through building the first package from the list before failing. It does however complete the next line, which is the last command in the script.

I'm running this on Arch Linux and sudo is set up. I'd like to possibly share this script down the road, so I'd like to keep as generic as possible. I edited the op to reflect this.

Why does building a list of packages requires to be user notroot? Are you on NFS?
– Bichoy
Sep 18 '15 at 6:00
This is an Arch Linux relate standard, to not build packages as root. In fact makepkg will not run as root. Arch has the AUR, Arch user repository. This repo contains build scripts rather than binary pre built packages. Anyone can contribute, mostly unchecked, so the potential is there for things to go wrong, either in error or malicious.

It's very hard to understand what you're doing since you don't show your scripts. Could you simplify this to an example script that reproduces the problem? If you need to run a single command as non-root, just usesudo -u user commandorsu -c command user.

I'm working on a Linux Bash script that needs to start as root. At the end of the script, it builds a list of packages. This requires running as user. Then it will move the packages, which needs to run as root again. I have sudo set up, but want to keep the script as generic as possible.
I've tried the following and slight variations of it in the first script to switch from root to user.
su -c - "$USER" "export PKGDEST=/tmp/test/AUR/"
su -c - "$USER" "pacaur --noconfirm --noedit -cm" "$(< /tmp/test/aur)"
The second line fails to run properly resulting in different errors, depending quote combination and placement. Running the lines within the first script as shown above produced the following error after reading the file /tmp/test/aur :: no targets specified (use -h for help). My preference would be getting this single script method to work properly.
Google, etc. said root, user, root in bash is bad, so tried break it into 3 parts:
- The first script runs as root. The problem centers here, can't get
it to start the second. - Second script runs as user, starts 3rd script as root with: sudo
/bin/bash "$L"/copyaur.sh - Third script, copyaur.sh runs, moving the packages properly but
doesn't show as running in the terminal because calls new shell?
Below was ran as su in a user terminal during testing. Prefer using the $USER var in the script.
As su in the terminal, then back to su - $USER, then ls in home lists my normal user name [dom's] contents.
[dom@arch testing]$ echo $USER
dom
[root@arch testing]# echo $USER
dom
[root@arch testing]# pwd
/home/dom/scripts/testing
I get the following results in testing, starting as su in the terminal. Want to get $USER var to work in place of dom.
su - $USER home/$USER/scripts/testing/buildaur.sh - No such file or directory
su --login $USER home/$USER/scripts/testing/buildaur.sh - No such file or directory
su - $USER home/dom/scripts/testing/buildaur.sh - No such file or directory
su - "$USER" home/dom/scripts/testing/buildaur.sh - No such file or directory
su - "$USER" ./buildaur.sh - No such file or directory
su - dom ./buildaur.sh - No such file or directory
su - dom ~/scripts/testing/buildaur.sh - Permission denied
su - $USER ~/scripts/testing/buildaur.sh - Permission denied
su --login dom ~/scripts/testing/buildaur.sh - Permission denied
su - dom /home/dom/scripts/testing/buildaur.sh - Runs as user, expected
su --login dom /home/dom/scripts/testing/buildaur.sh - Runs as user, expected
su - dom /home/$USER/scripts/testing/buildaur.sh - Runs as user, expected
9/19/2014 EDIT TO ADD REQUESTED INFO
Here's part of the script. Still no solution. This latest variation has made it through building the first package from the list before failing. It does however complete the next line, which is the last command in the script. Keep in mind this command works fine outside of using it with the proceeding su -c - "$USER" "pacaur --noconfirm --noedit -cm $(< /tmp/makeiso/aur)"
#!/bin/bash
## makeiso.sh must be run as root within /home/"$USER"/makeiso/releng
## makeiso dependancies: archiso pacaur

echo "This script must be run as root" 1>&2
exit 1
fi
# echo for a space
echo ""
# If passed root test, send message print message to user
if [[ $EUID = 0 ]]; then
echo "Passed root test, proceeding"

# Copy the prebuilt AUR packages to releng
cp -R /tmp/makeiso/AUR "$L"/airootfs/makeiso/packages/AUR
Here's the output with set -x. I'm using pacaur to build the packages, which uses cower and makepkg. It seems like either pacaur or makepkg is loosing track of the file with the list of packages to build, and doesn't recognize the package names as commands.

I'm running this on Arch Linux and sudo is set up. I'd like to possibly share this script down the road, so I'd like to keep as generic as possible. I edited the op to reflect this.

Why does building a list of packages requires to be user notroot? Are you on NFS?

This is an Arch Linux relate standard, to not build packages as root. In fact makepkg will not run as root. Arch has the AUR, Arch user repository. This repo contains build scripts rather than binary pre built packages. Anyone can contribute, mostly unchecked, so the potential is there for things to go wrong, either in error or malicious.

It's very hard to understand what you're doing since you don't show your scripts. Could you simplify this to an example script that reproduces the problem? If you need to run a single command as non-root, just usesudo -u user commandorsu -c command user.

The following worked as needed in my script to switch from root to $USER, then back to root.
sudo -u "$USER" bash << HereTag
command
command
command
# End Here Tag
HereTag
To review, I'm starting the script like this:
[user@linuxbox ~]$ su
Password:
[root@linuxbox user]# ./script.sh
After $ su, echo $USER shows my username. Even though I'm starting the script as root, I am prompted for a password @ sudo -u "$USER" bash.
I'm in the wheel group needing to provide password in suoders file.
I'd like to eventually figure out how to accomplish this without the need for sudo, but this will work for now.
