How to check if an application has been installed on a unix/linux box?
hi, guys,
now I face a problem. I have developed an application, and when it starts, it shall check if an application has been installed on the running linux/unix. If result is positive, i do something with the application command.
just as an example: I want to check if sshd has been installed. this requirement is supposed to be distribution independent. So
on my Arch box, usually "sshd" can be found at /etc/rc.d/sshd
however on a debian/ubuntu box, it usually is located at /etc/init.d/sshd
is there a general way, say give me the "/etc/rc.d" or "/etc/init.d" directory on the system?
thanx
