Reload profile in bash shell script in unix

Question

I m new to bash shell scripting  and have come across a challenge  I know I can reload my   profile  file by just doing      profile   but I m trying to execute the same in a bash script I m writing and it is just not working   Any ideas  Anything else I can provide to clarify   Thanks

The bash script runs in a separate subshell  In order to make this work you will need to source this other script as well

A couple of issues arise when trying to reload source    profile file   This refers to Ubuntu linux - in some cases the details of the commands will be different    Are you running this directly in terminal or in a script  How do you run this in a script    Ad  1   Running this directly in terminal means that there will be no subshell created  So you can use either two commands   source    bash profile   or       bash profile   In both cases this will update the environment with the contents of  profile file   Ad 2  You can start any bash script either by calling   sh myscript sh    or    myscript sh   In the first case this will create a subshell that will not affect the environment variables of your system and they will be visible only to the subshell process  After finishing the subshell command none of the exports etc  will not be applied  THIS IS A COMMON MISTAKE AND CAUSES A LOT OF DEVELOPERS TO LOSE A LOT OF TIME   In order for your changes applied in your script to have effect for the global environment the script has to be run with    myscript sh   command   In order to make sure that you script is not runned in a subshel you can use this function   Again example is for Ubuntu shell     bin bash  preventSubshell      if           0      then     echo  Script is being sourced    else     echo  Script is a subshell - please run the script by invoking   script sh command       exit 1    fi     I hope this clears some of the common misunderstandings   D Good Luck
