Shell wrapper for sudo

I posted about sudo here:

https://forum.puppylinux.com/viewtopic.php?p=117577#p117577

Which has brought this issue back to my attention. I really don't know why sudo was working and then it wasn't.

Anyway, I developed a simple alternative, named 'sudo-sh', see these blog posts mid-2023:

But what about an app that calls the sudo executable? EasyOS doesn't have sudo, QV does but it doesn't work.

To fix this, I created a shell script named 'sudo'. I don't know if an app will refuse to run it, if it sees it isn't a binary executable, or doesn't have suid bit set. Also, it ignores all commandline options. Anyway, here it is, /usr/bin/sudo:

#!/bin/ash
C=''
while [ -n "$1" ];do
 case "$1" in
  -*)
   case "$1" in
    -g|-p|-U|-u|-C|-r|-t)
     shift
    ;;
   esac
  ;;
  *)
   C="$@"
  ;;
 esac
 shift
done

if [ -n "$C" ];then
 exec sudo-sh ${PPID} ${C}
fi

This will only work in EasyOS and QV, that have sudo-sh. A simple test:

# su spot
# sudo urxvt

...a window pops up asking for the root password, then the urxvt terminal runs.

That sudo script is very simple, could be written in C.
