this piece of code, from /etc/.profile is not used properly.
# Prompt format for Ash (Bash use /etc/bashrc).
#
if [ "`id -u`" -eq 0 ]; then
# Light red and blue colored prompt.
#PS1='\e[1;31m\u@\h\e[0m:\e[1;34m\w\e[0m\# '
PS1='\u@\h:\w\# '
else
# Light green and blue colored prompt.
PS1='\e[1;32m\u@\h\e[0m:\e[1;34m\w\e[0m\$ '
#PS1='\u@\h:\w\$ '
fi
the colors (red for root, green for tc user) are not shown in aterm, neither in real terminal/console (Alt+F1). because the /etc/skel/.profile will overwrite them with simple code
# Environment variables and prompt for Ash SHell
# or Bash. Default is a classic prompt.
#
PS1='\u@\h:\w\$ '
export PS1
Maybe for tc user is better to have directly in /etc/skel/.profile
# Light green and blue colored prompt.
PS1='\e[1;32m\u@\h\e[0m:\e[1;34m\w\e[0m\$ '
Also, I can not activate the red color root-user. Using "sudo su" will not help. I can not login as root (by default), because /etc/passwrd
I can leave without these nice colors. But the idea is about the audit of TC script code.

I think we can leave those in, they can be examples.
Thanks for looking over the scripts.

Hi nick65go
... because the /etc/skel/.profile will overwrite them with simple code ...
User configuration settings are supposed to override system wide settings. That allows users to configure their preferences.
... Also, I can not activate the red color root-user. Using "sudo su" will not help. I can not login as root (by default), because /etc/passwrd ...
Did you try modifying the /root/.profile file? You will also need to backup /root if you make changes to it.

Hi Rich,I know that /home/.profile will take precedence over /etc/profile; and if I change something in /home/tc then I would need to backup it etc. I just highlighted that the code in /etc/.profile is NEVER used for prompter color. That code section can be deleted (curaga advised me that it can stay, as demo).
Also, I manually add a line in /root/.profile astc@box:~$ cat /root/.profile
#!/bin/sh
PS1='\e[1;31m\u@\h\e[0m:\e[1;34m\w\e[0m\# 'but the problem is (as I said it previously) that I can not login as root user. I tried to add a password to user root. It complaint that I need a strong one, so I chose one as "ABC123456789!" (with out " ")tc@box:~$ sudo su
root@box:/home/tc# passwd
Changing password for root
New password:
Retype password:
passwd: password for root changed by root
root@box:/home/tc# exit
tc@box:~$ login
box login: root
Login incorrect
box login: ^C
tc@box:~$
I think it is because something/somewhere not allow me as user root, just sudo su:
tc@box:~$ sudo su
root@box:/home/tc# cat /etc/passwd
root:x:0:0:root:/root:/bin/sh
lp:x:7:7:lp:/var/spool/lpd:/bin/sh
nobody:x:65534:65534:nobody:/nonexistent:/bin/false
tc:x:1001:50:Linux User,,,:/home/tc:/bin/sh
root@box:/home/tc#
root@box:/home/tc# cat /etc/shadow
root:$1$fXlnzkxU$li.1CDsMnFto.iMldZZNy1:18486:0:99999:7:::
lp:*:13510:0:99999:7:::
nobody:*:13509:0:99999:7:::
tc::13646:0:99999:7:::
root@box:/home/tc#
PS: in aterm says "login incorrect"; but in real console (crt+alt+f1) it accepts the password but instantly switch back to tc user.All was done live, no backup for /root, I just test from Xorg+flwm+aterm.
UPDATES: deleted everything from /root/.profile (keep just row with PS1); and now I can login from console (ctlr+alt+f1) with red color.But from Xorg (back with ctrl+alt+f2) still login error. I will exit from Xorg (crtl+alt+backspace) and come back here to report again.

Check root's files in /root. It redirects to user tc on purpose, for the boot autologin.

@curaga: correct! so I delete all from /root/.profile (keep just row with PS1). yes, I know it is crazy, just for testing. With this new /root/.profile I can login as root, and stay as root (red prompter), in console. Then from console I login as tc user, so I arrived in Xorg automatically. now in aterm as tc user I try login as root, and
tc@box:~$ login root
Login incorrect
box login:
box login: ^C
tc@box:~$
-
I don't think login is intended to work at a terminal like that. "su - root" Switches User to - login shell for root.
-
finally i managed, to log as tc user (green) and as user root (red).
So, 3 small things should be updated in /etc/profile:
1. proper comment of # Light red (not green) and blue colored prompt.
2. activate (uncoment) first PS1 line
3. comment out second PS1 line.
# Prompt format for Ash (Bash use /etc/bashrc).
if [ "`id -u`" -eq 0 ]; then
# Light red and blue colored prompt.
PS1='\e[1;31m\u@\h\e[0m:\e[1;34m\w\e[0m\# '
#PS1='\u@\h:\w\# '
2 things in /home/$user/.profile:
1. comment out first PS1 line.
2. activate /insert second PS1 line# Environment variables and prompt for Ash SHell or Bash. Default is a classic prompt.
# PS1='\u@\h:\w\$ '
PS1='\e[1;32m\u@\h\e[0m:\e[1;34m\w\e[0m\$ '
for ~/.profile is no problem, because it can be saved in mydata.gz
but for /etc/profile, maybe a remaster is in need. or else boot parameters "nologin +superuser" (aka root) has no red color, because /etc/profile is sourced imediatly after /init, no chance to be (eventually) restored from mydata.gz also. I did a remaster and is working.
Regarding login as root, staring as tc-user in a aterm-shell in Xorg, is OK. (my mistake, sorry).
The proper command I should issue is:tc@box:~$ sudo login -f root
