maybe you should run like this.I guess. two ways help you!

first:

mpirun --prefix /home/usama/.openmpi --hostfile hosts -np 4 . ~/.bashrc && bash script

second:

## 1. add this line to the script
. ~/.bashrc

## 2. run command as you do
mpirun --prefix /home/usama/.openmpi --hostfile hosts -np 4 bash script
