Corona,

I am referring to my post 3 days ago in which I tested that sudo does not inherit set -x option. That is fine. But i noticed another problem.
As you can see from my previous post above, the script invoked by 'otheruser' which calls the admin users's script with sudo is call_adminusers_restrictedsudocommand.ksh . While I got overwhelmed with trying to verify that set -x is not inherited by Sudo, I forgot to confirm at that time that sourcing the env file using sudo call to the admin script DOES actually propagate the environment variable exported inside the envfile.txt to the 'otheruser' script.

When i checked now it actually DOES NOT propagate. Am i missing something here ?
You must have changed how you ran it.

The correct procedure is sudo -> script, script sources file, script uses variables, script quits and takes everything with it, leaving the variables unavailable to the user and hence fully protected.

The variables are only available inside 'script'. That is the entire point. If they ended up in the user's environment, the user could just take them, so, you can't do that.

NAME
ipescript - Run an Ipe script (written in Lua) SYNOPSIS
ipescript script { arguments } DESCRIPTION
ipescript runs an Ipe script written in Lua. The Ipe bindings are automatically available in the script. Ipescript looks for the script in any of the script directories. The script argument should not contain the .lua extension. ENVIRONMENT VARIABLES
ipescript respects the following environment variables: IPELATEXDIR the directory where ipetoipe runs Pdflatex. IPESCRIPTS a list of directories where Ipescript will look for scripts. When this variable is not set, Ipe searches first the current directory, then ~/.ipe/scripts, and finally the system-wide Ipe script directory. When this variable is set, it should contain a list of directories, separated by semicolons. A single under- score is replaced by the system-wide Ipe script directory. IPEDEBUG set this to 1 for debugging output from ipescript. AUTHOR
Otfried Cheong REPORTING BUGS
Please report bugs using Ipe bugzilla at http://ipe7.sourceforge.net/bugzilla.html SEE ALSO
Ipe is documented fully in The Ipe Manual, which is available online at http://ipe7.sourceforge.net/manual/manual.html . August 28, 2011 IPESCRIPT(1)
