unix/system comand Always print out some environment setting when using it

When I use the command unix or system, it will always print out some settings in the screen, it really bothers me. Could anyone help me?

The first line following my command is not what I want. See these pictures for illustration. Thanks advance! Thank you very much!

what happens if you use the system with output variables [a,b]=system('pwd')

It will display nothing if I use [a,b]=system('pwd').

I found that it was because I used 'echo' in my cshrc file. After comment it, it fixes the problem and works fine as usual. Thank you anyway.

% Without semicolon:
system('pwd')

/users/mss.system.JTsOMg

ans = 0

% With semicolon:
system('pwd');

/users/mss.system.JTsOMg

% With semicolon and catching outputs:
[status, out] = system('pwd');
disp('ready')

ready

The last version helps.

I solved this problem by comment 'echo' in my unix environment setting. Thank you very much.
