How to avoid the system command execution sucessful message ?

Question

I am executing the following Perl command:

system ("cvs ci a.txt"); 

and it is displaying the CVS message. How to avoid this?

Answer 1

If you're going to be running system commands like this in a unix environment, the obvious thing works.

system("cvs ci a.txt > /dev/null");

You might want to consider something like IPC::Run3, too, to allow you to gather the output from stdout and stderr to use as you see fit.
