I'm trying to set an environment variable for a user session before running a script:
su - myUser -c "export myVar=$toto ; sh scriptThatNeedsMyVar.sh"
The scripts fails, I tried to debug and print myVar value:
su - myUser -c "export myVar=$toto ; echo $myVar"
returns nothing, that means that my env variable wasn't created although I'm creating and printing it in the same bash !
Then when I login as
myUserand type each command in bash console it works well
$su - myUser $export myVar=toto $echo $myVar toto
I'm I missing something ?
Why is this happening and how can I export a temporary variable as another user ( I'm not allowed to edit bashrc or any other system file)
