Question

I am trying to make an init.d script to launch my app.
I have two scripts, the first one is the init.d script myapp :

   #!/bin/bash
   export MYAPP_HOME="/srv/myapp"
   su - myuser -c "exec $COMMAND_LINE"

The second is a script to launch myapp.

I want to use the variable MYAPP_HOME in the second script.

Can anybody help me ?

The problem is that you are creating a login shell by using the - argument to su, so a new environment is created. Either don’t use a login shell (omit the -), pass the variable as a command-line argument, or place the environment variable in one of the start-up files, like .bash_profile.
