Hello Tru64 managers,
I found a weird problem with 'su', that is it looks like it's trashing
some environment variables.
The 'man su' says:
Except in a case where the - option is used, the user environment is
unchanged except for HOME, SHELL, USER, and LOGNAME which are taken from
the password file for the user being substituted (see environ).
Notably, this happens to me with LD_LIBRARY_PATH.
Please read here:
mgais % LD_LIBRARY_PATH=/usr/lib:/usr/lib/X11:/usr/shlib
mgais % export LD_LIBRARY_PATH
mgais % echo $LD_LIBRARY_PATH
/usr/lib:/usr/lib/X11:/usr/shlib
and now...
mgais % su
Password:
# echo $LD_LIBRARY_PATH
ÿ53ÿ141ÿ/usr/lib:/usr/lib/X11:/usr/shlib
With 'od' I could see that those weird chars are:
0xff _userUID_ 0xff _userGID_ 0xff
The problem is the same if I start with sh/bash/csh user shell
Root shell is sh
The problem seems to affect only for DU v4.0d/v4.0f machines,
not for Tru64 v5.0
If I type 'su otheruser', (with a sh/bash user) the
LD_LIBRARY_PATH will be unset
Of course, if I type 'su -', the variable is re-initialized correctly.
Could you please check if on your machine there is such a problem,
or if it should be something related to my login scripts ?
Thank you in advance
