system command
 

Is is a good practice to evoke a RTlinux object file from a normal linux file using system command??

Im afraid you're gonna have to give a bit more information than that.

Its basically like

i use a normal Linux file and in its main i take an input from a user. if the user says y then the RTlinux starts with the code system("rtlinux start filename.o");

Can this be used without any problems or should the rtlinux file be loaded differently in terminal by the help of >rtlinux start filename.o

There should be no problem with this. It doesn't matter how you are loading RTLinux runtime. However, it will not be a session leader in the shell. But, I cannot imagine how this will impact things.

As a person trained in "Web Application Security" - I have to inform you that if any malicious user found out that you are doing so - and your application doesn't do proper filtering and validation of the input parameters - you have a possible security vulnerability scenario waiting to be exploited here!
