No, it's really not.

The people that have chimed in have a combined experience of _well_ over a hundred years. Might just be they know a thing or 10?

You'd find that if there's another user account on your system (lets call it "fred"), and you ran 'su fred', it would not load ~fred/.bash_profile either, because it wasn't a login shell. 'root' isn't special here. > Isn’t moving from my own user using su, then prompted for password > count as a login? As you read in the 'bash' man page, files that are loaded with a "login shell" are different from files loaded from a normal shell execution. 'su' has specific syntax for either running a shell as a user or running a login shell as a user. Just typing a password at the prompt doesn't mean it was a login shell. Typically, a 'login shell' is what you get when you log into a system through login: or a graphical login. .bash_profile is loaded once when you log in. It's meant for login stuff. .bashrc is loaded for every shell you start. 'su' is a tool used to switch users, so you are given the option to either start a shell as a user or log in as that user, depending on the situation. > man su doesn’t apply to root with regards to the files loaded up > upon login.

Re: [CentOS] root .bash_profile?
$ man bash (INVOCATION) When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior. But the reference to .bash_profile has some unclear restrictions or boundaries: ~/.bash_profile The personal initialization file, executed for login shells First, the ~ which might not apply to root. Second, it’s a “personal” init file, which also might not pertain to root. Going from user to root (su) might not initiate a login shell. I’m not clear on this. But, .bash_profile is not loading. I have my aliases in another file called /root/.bash_aliases, which is a duplicate of my /home/myuser/.bash_aliases which is NOW sourced in my /root/.bashrc so it now works. So ya, got it to work, but knowing the cascade of inclusions is important. root is as important to me as my normal user. > On May 13, 2019, at 1:17 PM, Christian, Mark wrote: > > $ man bash, search on INVOCATION Cheers, Bee ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

No, this isn’t a case of multi partitions, clusters, or anything silly. I just want a set of aliases loaded for su. /root/.bash_profile isn’t loading, and there isn’t any obvious choice as to where the loaded .bash* were loading from. > On May 13, 2019, at 9:11 AM, Stephen John Smoogen wrote: > > While moving /root to /home/root is done in someplaces, it only works if > /home is not on a different partition.

Re: [CentOS] root .bash_profile?
OK, I haven’t tested for that loadup yet, and the .bashrc is indeed there. I thought .bashrc was loaded first, then .bash_profile. This is for normal user. Just tested it again, and /root/.bash_profile is not loading. Tried this in /root/.bashrc: source /root/.bash_profile That created a loop, because that reverse instruction is inside /root/.bash_profile So for some reason, entering su isn’t loading its own .bash_profile nor keeping my user’s .bash_profile (expected).

Ah thank you. Having forgotten this, I already had all my aliases and instructions in there. For some reason they aren’t loading. If I do this, then everything loads: source /root/.bash_profile So there’s an indication this isn’t loading upon entry into su.

Just wondering how I can implement an automatic .bash_profile for root. I have to load my user .bash_profile every time I get into root, and I would like a better solution. There is no /home/ for root, so I’m a bit confused if this is even allowed. Any insight appreciated.

This was because /home was not guaranteed to be mounted when the system started up AND people were annoyed with the Unix tradition of having UID 0 with the / as the home directory. [Having UID 0 with / caused all kinds of file components to show up in / and sometimes with the worst permissions.. so any user might source through /.history and find some password etc.] While moving /root to /home/root is done in someplaces, it only works if /home is not on a different partition. If you put /home on a different partition you will find all kinds of weird behavior happening on start up. > Any insight appreciated. > > > Cheers, Bee > > > > > ___ > CentOS mailing list > CentOS@centos.org > https://lists.centos.org/mailman/listinfo/centos > -- Stephen J Smoogen. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] root .bash_profile?
The following one liner should display root's home directory: grep -w ^root /etc/passwd | cut -d: -f6 Which finds the line beginning with the word root, and returns the sixth entry (the home directory of that entry).
