Alias syntax for mpirun

Question

I execute my jobs in terminal using:

mpirun -np 4 lmp_fedora < in.stdinfile

Now I want to create a permanent alias run so that I can just input the command:

run < in.stdinfile

from any directory in the terminal to execute my jobs. What is the syntax for the alias or the environment variable?

Apologies for removing your thanksgivings from your question, but as it stands the community prefers the questions to have the lowest noise-ratio as possible in their body; I don't really agree with this, but this is how it stands; However, I think that reporting them in the comments section, if you're willing, should be fine. — kos, Jul 07 '15 at 02:34

In this case the alias would be:

alias run='mpirun -np 4 lmp_fedora'

The canonical way to add an user-defined local alias is to put it into ~/.bashrc; you can directly add it to ~/.bashrc using this command, which will append it to the end of the file:

echo "alias run='mpirun -np 4 lmp_fedora'" >> ~/.bashrc

Then you can run source ~/.bashrc to apply the changes in your current bash instance:

source ~/.bashrc
