To Enable Syntax Highlighting in VI

To Enable Syntax Highlighting in VI and VIM and to add alias function to VI by pointing to VIM, just mention as follows
alias vi=vim

Example

[root@linuxhelp Desktop]# vi /etc/profile
# /etc/profile
# System wide environment and startup programs, for login setup
# Functions and aliases go in /etc/bashrc
# 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.
alias vi=vim

pathmunge () {

This given function will set the alias globally.

To set user specific aliases and functions

Example

[root@linuxhelp Desktop]# vi /home/user1/.bashrc
# .bashrc
# Source global definitions
if [ -f /etc/bashrc ]  then
        . /etc/bashrc
fi
# User specific aliases and functions
alias vi=vim
