For my memo only , now the solution is  avoiding or get rid of  error message  coming out after login but it is needed to find out the root cause of  perl command error in other new thread in future if need


perl command:   perl -Mlocal::lib

errror message which is deleted after login by this thread solution:

I see we crossed over!  Glad we sorted it out.

If you start a login shell (e.g. when you log in, or if you run "su -"), /etc/profile is called, then it looks for .bash_profile .bash_login and .profile in that order, and sources the first one it finds .

If you start a non-login shell (e.g. you type "bash" at the shell prompt), .bashrc is called.  In your .bashrc, you can see that it in turn sources /etc/bashrc.

So, .bash_profile is the personal login profile file, and /etc/profile is the global one for all users.  Similarly .bashrc is per-user, and /etc/bashrc (if your .bashrc looks like it does here) is global.

Thanks for your reply

//-sh script running in profile
=====================
for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
        if [ "${-#*i}" != "$-" ]; then
            . "$i"
        else
            . "$i" >/dev/null 2>&1
        fi
    fi
done
//----------For  comment bashrc file------
if [ "$LOCALLIBUSER" != "root" ]; then
    eval $(perl -Mlocal::lib)
fi



in profile file, there is sh script running and  there is perl command saved in /profile.d/locallib.sh, just rename  it and
in bashrc, there is also perl command about perl -Mlocal::lib, just comment it
both is done and then the error message is removed.

Found it,  what is different between /etc/profile and /etc/bashrc ?

and what is different between .bashrc and /etc/bashrc ?

They're not account-specific - they are files called /etc/bashrc and /etc/profile which are called for all logins - I'd be surprised if they weren't there.

Which specific version of Linux are you using?

there is no such two directories  at root or user account after checking
