[lfs-support] About errors

2013-06-06 Thread Philippe Delavalade 
Hi :-)

I prefer a second message for another problem.

On my debian host system, in files .bashrc, i use the following lines to be
informed from errors in a command :

if [ $PS1 ]; then
_prompt_command()
{
 local status=$?;
 if [ $status != 0 ]; then
 echo -n $status  12;
 fi 
}
PROMPT_COMMAND=_prompt_command
fi

So, the exit code is printed before the prompt in case of an error.

I'd like to do so in chapter 6 of LFS but, as there is no .bashrc, I wonder
where I could append this lines.

Thanks for advice.

I haven't tried, but I would say that it could go in .bashlogin in 
/root. Then if you use the chroot command of 6.4, .bashlogin is sourced.

Thanks but I have just .bash_history in /root.

Did I missed something ?

Sorry, I meant, put the lines from _prompt_command() to 
PROMPT_COMMAND=...
into $LFS/root/.bashlogin (using copy/paste or an editor), and then
chroot using the command on page 6.4.

Just add it. Or put into $HOME/.bashrc . It doesn't matter if you don't
have the file RIGHT NOW, when you make it, bash will read and use it.

Like this (one of several ways to do this):
$ cat  $HOME/.bashrc  EOF
 your stuff goes in here 
EOF

Yes, I have understood ; but in /$LFS/root I have just .bash_history.

Maybe I can create it as suggest Aleksandar Kuktin.
