Linux version

Fixit7 · 05-12-2014, 03:02 PM

I would like my scripts to be able to work with different versions of Linux.

I have Puppy Slacko 5.6 installed, but uname is showing something different.

From uname

Linux 3.10.5 i686

From Pup Sysinfo.

Distro: Slacko Puppy 5.6.0

I also tried cat /proc/version

uname is showing the kernel version, not the OS version. cat /proc/version also outputs the kernel version.

For example, on my Debian Sid system, uname -a outputs this:

Code:

:~$ uname -a
Linux tuna 3.12-1-686-pae #1 SMP Debian 3.12.9-1 (2014-02-01) i686 GNU/Linux

meaning kernel v. 3.12.9-1.

In contrast,

Code:

~$ cat /etc/*release*    
PRETTY_NAME="Debian GNU/Linux jessie/sid"
NAME="Debian GNU/Linux"
ID=debian
ANSI_COLOR="1;31"
HOME_URL="http://www.debian.org/"
SUPPORT_URL="http://www.debian.org/support/"
BUG_REPORT_URL="http://bugs.debian.org/"

cat /etc/*release*
gave this:

cat: /etc/*release*: No such file or directory

Within reason it should not matter which kernel version or which distribution or version of that is running for a script to work. But it depends what you want the script to do?

Great, IMHO, it's a good idea to make your scripts portable. Do you have any questions related to this?

Cheers,

Thanks.

For my needs, it does matter.

There are are many distros of Linux.

And each of them have different commands.

And that is what makes all of them unique.

Ok, so you are concerned about the presence or absence of a command? If so, the normal approach is normally testing for the existence (and possibly behaviour) of that command, not trying to determine the exact operating system version. If you tell us what you are actually trying to achieve, and then ask related questions, I think you'll probably get more useful answers.

You could try: cat /etc/issue

Some Linux distributions have a release file, some have an issue file and some have both.

Fixit7 · 05-13-2014, 01:27 PM

# cat /etc/issue
Slacko Puppy Linux
Linux 3.10.5 [i686 arch]

evo2 · 05-13-2014, 05:19 PM

Hi,

once more, do you really care what distro and version your script is running on? There are literally thousands. Please tell us what you are actually trying to achieve and we may be able to help.

No need to make a script. It has already been done.

http://code.google.com/p/inxi/

Install instructions are on that page. It works on everything.

One of us is misunderstanding what the OP is trying to do.

As far as I can tell the OP has scripts that (s)he wants to run on different machines. The OP is under the impression that to run these scripts (s)he first needs to determine exactly what OS the script is on. I've tried to point out that trying to determine the OS is neither necessary nor very useful.

I think your interpretation of the OP post is that (s)he is trying to write a script that will determine what OS it is being run on.

OP: can you _please_ clarify what it is you are trying to achieve.

cat /etc/*release* is a sort of a shotgun of a command loaded with wildcards instead of buckshot.

Most of the time, it hits a target. Sometimes not.

Yes, that is exactly what I would like to do.

For example this works on Puppy but not on other distros.
They probably use poweroff.

I also run one other distro.

Code:

#!/bin/bash
#     Linux Puppy 6.5.0
# This powers off Linux Puppy !
#

wmpoweroff

???? You just contradicted yourself.

If you want to know what command to use to shut down a machine, test what commands are available. If instead you try to test for what the OS is you'll need to populate and maintain a database of all possible OSs, and the corresponding commands for each OS.
