EXTRA - PROFILES

/etc/profile:
System wide profile.  All variables set here may be overridden by a user's personal .profile file in their $HOME directory. 
However, all commands here will be executed at login regardless.

#Extended history
export EXTENDED_HISTORY=ON
alias history='fc -lt'


$HOME/.profile:

export HOSTNAME=$(hostname)
export PWD=$(pwd)
export PS1="`whoami`@`hostname`: "'$PWD'" # "
export ENV=/.kshrc        <--ENV variable specifies which script (.kshrc) to be invoked every time a new shell is created

PS1 color settings:
If I want 'hostname' with other color in my PS1 (#export PS1="`whoami`@`hostname`: "'$PWD'" # ")

add before `hostname`: ^[[01;32m        <-it will set to green the color
                                       (in vi insert mode ctrl+v will make "^" and after that hit 'esc' it will do the first "[")
                                       (second "[" is a normal bracket)
add after `hostname`: ^[[0m            <-it will set back to original color (same keys as above)

-----------------------------------------------
After modification logout is necessary in order the changes take effect.

$HOME/.kshrc
This file (by default, but it can be overwritten in .profile ($ENV)) will be invoked every time a new shell is created. It is useful to define aliases in this file.
