Need help about bash profile file.


Hi,
I want to know the difference between the following files

1- .bash_profile
2- .bashrc
3- .bash_logout

These three files are located in with their respective names under the following dir

/etc/skel
/home/user1


Further when i login into terminal i see the login prompt as
[user1@localhost user1]$

I want that when user2 will login he automatically login into
[user1@localhost /]$

the output when i use
[user1@localhost user1]$cat .bash_profile
------------------------------------------------------------------
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:

export PATH
unset USERNAME

----------------------------------------------------------------


Please guide me.Thanks in advance.

These files are described in the bash man page:

Code:
       ~/.bash_profile
              The personal initialization file, executed for login shells
       ~/.bashrc
              The individual per-interactive-shell startup file
       ~/.bash_logout
              The individual login shell cleanup file, executed when a login shell exits
When a new user account is created, any files in /etc/skel/ get copied to the new users home dir.

The Bash startup files are explained here.

The /etc/skel files are used when setting up a new user. Any files in /etc/skel are copied to the new users home directory. More info in the useradd (and adduser?) man page.

The command prompt is configured using the $PS1 variable, set in the Bash startup files. Special characters used in PS1 are described here.

The PATH and login prompt are completely unrelated. If you want to modify the login prompt you need to set the PS1 variable. There are a huge number of tutorials on this topic on the web. For example, this was the first hit when I googled:

bash howto set prompt

Hi,

You could setup a .bashrc & .bash_profile for your user, maybe a sample will aid;

Code:
sample .bash_profile;

~$ cat .bash_profile
# .bash_profile
#08-30-06 12:21
#
# Source .bashrc
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi
Code:
sample .bashrc;
:~$ cat .bashrc

#.bashrc
#08-30-06 12:20 

# Add bin to path

export PATH="$PATH:/sbin:/usr/sbin:$HOME/bin"

#export PATH="$PATH:$HOME/bin"

# Dynamic resizing
shopt -s checkwinsize

# Custom prompt
#PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

#08-29-06 11:40

if [ `id -un` = root ]; then
   PS1='\[\033[1;31m\]\h:\w\$\[\033[0m\] '
 else
   PS1='\[\033[1;32m\]\h:\w\$\[\033[0m\] '
fi

#
# Add color
eval `dircolors -b`

# User defined aliases
alias cls='clear'
alias clls='clear; ls'
alias ll='ls -l'
alias lsa='ls -A'
alias lsg='ls | grep'
alias lsp='ls -1 /var/log/packages/ > package-list'
alias na='nano'
alias web='links -g -download-dir ~/ www.google.com'

#08-29-06 11:50

#To clean up and cover your tracks once you log off
#Depending on your version of BASH, you might have to use
# the other form of this command
   trap "rm -f ~$LOGNAME/.bash_history" 0

#The older KSH-style form
#   trap 0 rm -f ~$LOGNAME/.bash_history
The .bashrc is very useful!

Plus as others have stated you can always 'man bash' to get some understanding.

Look at these useful links;

Linux Documentation Project
Rute Tutorial & Exposition
Linux Command Guide
Linux Newbie Admin Guide
LinuxSelfHelp
Getting Started with Linux

These links and others can be found at 'Slackware-Links' .
More than just SlackwareŽ links!
