I thought I was submitting a program to run on Unix (solaris) in background mode ("&") by using the following syntax. 

@command = ("/bin/nohup /mevs/$version/bin/mevs", "/mevs/$version/data
+/config_data/mevs2.cfg", "online");

system(join " ", @command, "&");  # restart pgm in background

However, when I issue the "ps -ef" command the "&" shows up as part of the command line display. I'm wondering now if the "&" is being considered as another $ARGV instead of requesting the program be run in the background. I use the above syntax instead the following: 

@command = ("/bin/nohup /mevs/$version/bin/mevs", "/mevs/$version/data
+/config_data/mevs2.cfg", "online", "&");

system(@command);

Is the first approach the correct way to submit a job to run in the background?

I am just a little confused and any help you can provide is greatly appreciated. Thanks.
