Getting a process/program version from /proc folder
Hello

I am writing a script that will first execute ps to get the list of processes running, and the go into the /proc folder for each PID listed and gather relevant information.

I looked through the contents of a particular process in the /proc folder and I can't find where I can locate the version of the running process/program.

Ideally I don't want to get the name of the program and then execute a command to get the version of the program, because I am trying to write a script to do this constantly across a variety of machines; although most programs can reveal their version numbers using --version tag, it is not reliable and may differ per program.

Can anyone help?

Thanks

It would be nice, but it's certainly not something you can extract from /proc/. Processes and executables don't really have that kind of embedded information. You'll have to deal with the programs and OSes the hard way.

There's systems that don't even have /proc by the way, like OSX and HPUX.
