Hi Hubert,
your suggestion works fine running for nested scripts, I created 3
script testa -> testb -> testc like this :
lx1iard0:~ # cat testa
#!/bin/bash
echo "testa => SHLVL="$SHLVL
sh /root/testb
exit
lx1iard0:~ # echo $SHLVL
1
lx1iard0:~ # sh testa
testa => SHLVL=2
--testb => SHLVL=3
----testc => SHLVL=4
But.... the variable $SHLVL is always 1 after a "su - " :
it32...@lx1iard0:~> echo $SHLVL
1
it32...@lx1iard0:~> su -
Password:
lx1iard0:~ # echo $SHLVL
1
lx1iard0:~ #
I customized the profile.local and it launch a script_xxx at login. When
use 'su - ' I would like that the new user does not execute the
script_xxx again.
Cordiali saluti / Best regards

Re: Which user env. variable tell me that it is in "s u - " mode ?
Hi Marco,
try:
echo $SHLVL
The value is incremented for each new sub shell - so it will be "1" for
login shells (which you get with "su - ..."
