May 8, 2018 · The closest of the feeling of a contemporary system you can get freely in the Internet, and pretty much tested and ready to run, is a version 7 disk image running with the PDP-11 SimH emulator, and even a system III disk image with the actual C sources also with the PDP-11 emulation under SimH.

Jan 27, 2019 · What do you mean by UNIX? The last "true" Bell Labs unix was Version 10 from 1989, never released to the public. Most modern UNIXes descend ultimately from Version 7. The history of UNIXes is very messy, a brief version is available here. From there, it gets very messy. You can trace UNIX from there to either (closed-source) System V UNIX or BSD.

Kernel Version. If you want kernel version information, use uname(1). For example: $ uname -a Linux localhost 3.11.0-3-generic #8-Ubuntu SMP Fri Aug 23 16:49:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Distribution Information

Jul 28, 2019 · I'm going through the 'Unix Programming Environment' classic by Kernighan and Pike. I discovered there was a very interesting command written by Kernighan and someone else called learn for computer aided instruction on Unix subjects like editing, macros and even C in version 7 and, it seems some of the BSD's. I've got a copy of Version 7 up and ...

Apr 1, 2015 · I have seen a few ways to get information about the system you're using, but are there some standard commands to tell me what version of Unix/Linux I'm on and basic system information (like if it is a 64-bit system or not), and that sort of thing?

Aug 4, 2021 · I also found that all the CentOS 7 servers I queried all have the same kernel version (3.10.0-693) by running uname -a. These servers are all running CentOS 7 but the dot version varies from 7.2 to 7.9. $ uname -a Linux myhostname 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

For your case I believe the correct distribution version is placed into the *-release file in /etc, since /proc/version just reflects linux kernel release and build host (I think). Also there is a facter ruby gem, which gives you some facts about os OS, it analyzes OS release files, other data and prints to terminal screen.

Mar 26, 2014 · Unix version 7 hier(7) manual page defines /usr as the default location for user's home directory: /usr/wd/ initial working directory of a user, typically wd is the user's login name Unix version 6, the first Unix to be widely released outside of the Bell Labs had not the hier manual page yet but was already using and documenting /usr.

The Unix/Linux community has never had a three-character limit on extensions and frowns upon shortening well know extensions to fit. For example, don't use .htm at the end of HTML files on Unix/Linux, use .html. In a set of files, a filename is sometimes capitalized, or in all caps, so it appears at the head of a directory listing.

Sep 27, 2018 · $ php -r 'echo PHP_VERSION;' 7.1.15 You can extend this pattern to get more, or less, information: $ php -r 'echo PHP_MAJOR_VERSION;' 7 See the PHP list of pre-defined constants for all available. The major benefit: it doesn't rely on a defined output format of php -v. Given it's about the same performance as a pipeline solution, then it seems ...
