reparatie bash

Daca are cineva timp, il rog sa lamureasca un incepator asupra configurarii bash_profile.
M-am jucat cu permisiunile avansate chmod u+s ... asupra bash-ului si acum nu pot sa-l mai fac la loc.

Acum am:
[root@Tester etc]# echo $PS1
[\u@\h \W]\$
[root@Tester etc]# exit
exit
bash-4.2$ whoami
alice2
bash-4.2$ echo $PS1
\s-\v\$

Vreau ca in userul alice2 sa vad din nou CLi-ul de tipul [\u@\h \W]\$
daca declar $PS1='[\u@\h \W]\$ ' merge pana la primul exit, apoi reapare forma fara user (\s-\v\$)

am incercat sa modific .bash_profile in alice2~ doar ca nu il citeste:

[root@Tester etc]# cat /home/alice2/.bash_profile
# .bash_profile
# Get the aliases and functions
#if [ -f ~/.bashrc ]; then
#    . ~/.bashrc
$PS1="[\d \t \u@\h:\w ] $ "
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH
export PATH=/usr/local/bin:$PATH

.bashrc din profilul curent (alice2):



[root@Tester etc]# cat /home/alice2/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=
# User specific aliases and functions





ma indreapta catre /etc/bashrc care arata asa:

[root@Tester etc]# cat bashrc
# /etc/bashrc
# System wide functions and aliases
# Environment stuff goes in /etc/profile
# It's NOT a good idea to change this file unless you know what you
# are doing. It's much better to create a custom.sh shell script in
# /etc/profile.d/ to make custom changes to your environment, as this
# will prevent the need for merging in future updates.
# are we an interactive shell?

nu vreau sa incep sa modific pe aici ca inca nu pricep tot.
daca are cineva timp sa ma lumineze, pls help.

am incercat sa creez un user nou si bash lui arata tot de tipul \s-\v\$
am incercat si yum reinstall -y bash, la fel.

probabil deci trebuie facuta o modificare in /etc/bashrc si as dori asistenta inainte sa reinstalez cu totul

ls -lash ~/.bash*

Si pune output-ul aici.
Sau:

find /home/alice2/ -type d -exec chmod u+rwx '{}' \;
find /home/alice2/ -type f -exec chmod u+rw '{}' \;

multumesc pentru raspuns kagaroth

[root@Tester etc]# ls -lash ~/.bash*
8.0K -rw-------. 1 root root 6.4K Feb  8 13:01 /root/.bash_history
4.0K -rw-r--r--. 1 root root   18 Dec 29  2013 /root/.bash_logout

[root@Tester etc]# find /home/alice2/ -type d -exec chmod u+rwx '{}' \;
[root@Tester etc]# find /home/alice2/ -type f -exec chmod u+rw '{}' \;
[root@Tester etc]#

Ma interesa sa vad ce permisiuni ai pe fisiere. Vezi pe /home/alice2 ce  permisiuni ai. Promptul ala, bash-4.2 apare cand esti user alice2? Asa pare din ce ai postat. Intra ca user alice2 si da comanda(zile) whoami si id  si posteaza aici rezultatele. Incearca si comanda de mai jos pe care o dai ca user root:

chown -R alice2:alice2 /home/alice2

Ah ca si user alice2 da comanda:

echo $PS1

In ~/.bashrc poti incerca:

export PS1="[\u@\h:\l \W]\\$ "

La fel si in ~/.bash_profile

da, asa e, forma scurta aparea doar in userul alice2 (precum si la adaugarea de useri noi)
owneri erau toti cu permisiunile implicite fara sticky bits sau permisiuni speciale.

am mers cu export PS1="[\u@\h:\l \W]\\$ " in ~/.bashrc si ~/.bash_profile

multumesc!
