set an environment variable in Linux 7

 Usually there are two ways to setup environment one is for separate user and another one is for all user

# env   //used to check the current environments

# export  //used to check the current environments

//we can use export command to set an environment but that was an temporary

#export DSPRING_PROFILES_ACTIVE=uat  

# env

DSPRING_PROFILES_ACTIVE=uat

# export

declare -x DSPRING_PROFILES_ACTIVE="uat"

# echo $DSPRING_PROFILES_ACTIVE

//if you wan to make this variable for permanent for all user then need to put this entry in to profile

# vi /etc/profile

//add this line at bottom of the page

export SPRING_PROFILES_ACTIVE=uat

//if you want to make this for single user then put them into particular user .bashrc file or .bash_profile

# vi /home/username/.bashrc

//add this line at bottom of the page

export SPRING_PROFILES_ACTIVE=uat

# vi /home/BOOBI/.bash_profile

//add this line at bottom of the page

export SPRING_PROFILES_ACTIVE=uat
