How to use background execute in bashrc with alias?

I want to replace complex commands with simple characters and execute in background, so I can shut down the terminal.

The command is nWave -ssf test.fsdb(fsdb is a wavefile). In bashrc, I write alias nwave='nWave -ssf'.

If I want the command to be executed in background, I use nWave -ssf test.fsdb &. How to realize this command when using alias in bashrc file.

If you plan to close the terminal, you probably want to wrap the command in nohup. However, using 'nohup alias ...' will not work - as nohup only accept regular command. You can embed the nohup into the alias explicitly.

# In bashrc
alias bgnwave 'nohup nWave -ssf'

# At the terminal
bgnware test.fsdb &

As an alternative to bash alias, consider using bash function

function bgwnwave {
    nohup nWave -ssf "$@" &
}
