setup of a program for all users

[pankos]

if a program must be used by all users of a linux system then where i setup this? Must i connect as root and after do the installation? The .bashrc file af each user will be changed automatically?

A program intended to be used by all users needs to be in one of the $PATH locations.
Do an echo $PATH as one of your users to see them.

Only root can copy to non-home bin directories.
If you intend to become root and deploy programs, then I strongly suggest to package (RPM/deb) them first.
This helps a lot maintaining them in the long run.

I agree, package your installation. At the very least, start with writing a script that does your installation for you (including things like creating/modifying user profiles, etc.). You can then use that as a model for when you get into "official" packaging techniques.

Therefore, if i copy the path of executable file to path of all user , it would be opened by all?

[Irithori]

Any user should have /bin:/usr/bin:/usr/local/bin
A program in any of those locations is available to all users (correct permissions on it are assumed)

Without package control, /usr/local/bin is the least intrusive choice.

And if you prefer to install your app to some non-standard location (i.e., /opt/myapp), you could use the global profile scripts in /etc/profile.d/ so that all users would get the path. You can put one there for bash-type shells and one for csh-type shells. for example, a bash profile script called /etc/profile.d/myapp.sh might look like:

if [ -d /opt/myapp/bin ]; then
  echo $PATH|grep -q /opt/myapp/bin && : || export PATH=/opt/myapp/bin:${PATH}
