vi /etc/profile 안의 내용 - 파란줄만 설정하면 의사분산모드에서 전역에 등록하는법

# /etc/profile

# System wide environment and startup programs, for login setup

# Functions and aliases go in /etc/bashrc

# It's NOT good idea to change this file unless you know what you

# are doing. Much better way is to create custom.sh shell script in

# /etc/profile.d/ to make custom changes to environment. This will

# prevent need for merging in future updates.
