Top Forums UNIX for Beginners Questions & Answers Another one line command where I'd like to determine if Ubuntu or Red Hat when running command Post 303040494 by drl on Wednesday 30th of October 2019 09:10:25 AM

Hi.

We use a variety of platforms, so we often need to identify the one on which we are working. Here is a sampling showing the use of:
  1. GNU script config.guess,
  2. file /etc/issue,
  3. standard *nix command uname,
  4. our local code version
Our code version is really for displaying versions of commands and scripts, but we found it convenient to identify the OS as an option as well as displaying a code version. We make use of uname for a number of elements in the display, but AIX and macOS, for example, need special processing. The code is probably not completely general, but the design it has suited our variety of OSs quite well. However, while the call to it is a single-line, the devil in the details requires a lot of extra code, and is, most emphatically, not a single-line.
Code:
config.guess:
x86_64-pc-linux-gnu
/etc/issue:
Debian 10.0 (buster) \n \l
uname:
Linux vm-buster 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u2 (2019-08-08) x86_64 GNU/Linux
(local) version:

config.guess:

/etc/issue:
cat: /etc/issue: No such file or directory
uname:

(local) version:

Distribution        : Solaris 11.3 X86

config.guess:
x86_64-apple-darwin18.7.0
/etc/issue:
cat: /etc/issue: No such file or directory
uname:
Darwin lmin 18.7.0 Darwin Kernel Version 18.7.0: Tue Aug 20 16:57:14 PDT 2019; root:xnu-4903.271.2~2/RELEASE_X86_64 x86_64
(local) version:
OS, ker|rel, machine: Apple/BSD, Darwin 18.7.0, x86_64
Distribution        : macOS 10.14.6 (18G103), Mojave

Some details for config.guess:
Code:
config.guess    guess the build system triplet (man)
Path    : ~/bin/config.guess
Version : GNU config.guess (2016-02-11)
Length  : 1455 lines
Type    : POSIX shell script, ASCII text executable
Shebang : #! /bin/sh
Help    : probably available with -h,--help
Home    : http://savannah.gnu.org/projects/config (doc)

Best wishes ... cheers, drl
