Hello again!
i there with locale problem - i set it up in /etc/profile.d/lang.csh & lang.sh set to en_US.UTF-8
now user locale reports a UTF-8, and that's is ok.
but when i su to root, and look root locale, output to command "locale " shows:
LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=


very strange to me. as so, under root i see undefined symbols in file and catalog names in cyrillic and so on.
have a two questions - i thinked, a lang definet in profile.d is system- wide lang definition? for what it is not affect to root user?
and what i can change root's locale ?

Scripts in /etc/profile.d/ are only read by login shells. If you use `su -` instead of just `su` you should get the proper locale settings. If you want them in non-login shells as well, then you should add the same export/setenv command to root's .bashrc (or other equivalent for whatever shell you use).

ok, thank you!
