Re: Adding/modifying users under MATE DE

Because I (at least) once read somewhere something like: "retirement, what is 
it for if not for learning" I'll mention that *maybe* the  suid bit would be 
helpful for what you are trying to do.

I say this without really following what you are trying to do, and without a 
real good memory of how the suid bit works (but I did use it at least for one 
script back "in the day".

Looking at your first paragraph, you might make your Tcl script to be owned by 
root, and then give it the suid bit.  Then, iir/uc, anybody could run that 
script, and that script would be able to run dumpe2fs.

That's iirc.  And maybe what you want to do is almost the opposite.
