Do you want this to be a Global setting or Local per user?

Global
I'm using Debian so I'm not sure if the file is the same in RedHat.
Edit as root /etc/bash.bashrc and add the alias.

Local
Edit each users ~/.bashrc file and add the alias

Note: Some linux OS do not have a local .bashrc file, if not just create the file. To do this, in the home directory of the user run the command.

touch .bashrc

Now edit the file and add the alias.

When you install Linux you usually get bash as the default shell. I use the C-shell instead for interactive
work (though I use bash for writing scripts). When you log in it runs the file ~/.tcshrc and in this I have
put things like

alias rm 'rm -i'
alias cp 'cp -i'
alias mv 'mv -i'
alias cat 'cat -v'
alias gt 'set D1=$cwd;cd $1'
alias gb 'cd $D1'
alias ls '/bin/ls -F'

and these all work from then on. I believe you can do something similar in bash using functions but this
way is easier.

It depends on the shell you use.

For bash, check the bash man page, section "Invocation". There you have a list of all the files that are used depending on the mode, and their order of precedence.

Hi,

You could setup a .bashrc & .bash_profile for your user;

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

You can modify the '.bashrc' above for a user to reflect the environment for that user.

The .bashrc is very useful!
