*Linux tips [#ie40dc7a]
**Environmental setting [#k4e29c9d]

Create ".bash_profile" in the home directory and write the following, if not exist.

 vi ~/.bash_profile

In .bash_profile:

 if [ -f ~/.bashrc ]; then
         . ~/.bashrc
 fi

Create ".bashrc" in the homedirectory to set prompt, add command line path, and so on.
Below is an example of ".bashrc"

 if [ "$PS1" ]; then
 
     # enable color support of ls and also add handly aliases
 
     #eval `dircolors`
     #alias ls='ls -F --color=auto'
     alias ls='ls -FG'
     alias ll='ls -l'
     alias la='ls -A'
     alias cp='cp -i'
     alias mv='mv -i'
     alias rm='rm -i'
 
     # set a fancy prompt
 
     PS1='\u@\h:\w\$ '
 
 fi

To add a command search path, add the following (for instance) to ~/.bashrc

 export PATH=${PATH}:${HOME}/qe-6.1.0/bin:${HOME}/qe-6.1.0/PW/tools

and type

 source ~/.bashrc

to make the change.
