Every new command is wrapped in a tweet and posted to Twitter. Following the stream is a great way of staying abreast of the latest commands. For the more discerning, there are Twitter accounts for commands that get a minimum of 3 and 10 votes - that way only the great commands get tweeted.

Found in comments section works on most Linux flavors.

rpm -qf /etc/*-release

This should work on any RPM-based distribution. It's more reliable than trying to parse the content of the files.

Know a better way?

Doesn't work with Gentoo

Is lsb_release a better command for this?

Comment by int19h 297 weeks and 4 days ago

ls /etc/*release

is better IMO, "issue" contais welcome message

Comment by unixmonkey1054 297 weeks and 4 days ago
ls /etc/*release

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

cat /etc/issue

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

uname -rms

FreeBSD 7.1-STABLE i386

uname works better

Comment by grep 297 weeks and 3 days ago

How about this one, does it work for everybody?

grep -qs "" /etc/lsb-release && lsb_release -a | grep -v n/a | grep -v none; uname -rms

Comment by int19h 297 weeks and 3 days ago

Checked it on Solaris, and noted that no such info was printed - it was a custom message set by the admin.

Comment by rommelsharma 297 weeks and 2 days ago

Hrm.. How about

test `uname` = Linux && lsb_release -a || ( test `uname` = SunOS && cat /etc/release || uname -rms )
Comment by mulad 297 weeks and 1 day ago

Here's a csh script I use to find the OS version. Works on various Linuxes and Mac OS X:

#!/bin/csh -f

if(-r /etc/fedora-release) then

cat /etc/fedora-release

else if(-r /etc/lsb-release) then

perl -ne 'if(/DESCRIPTION/) { s/.*="(.*)"/$1/; print; }' /etc/lsb-release

else if(-r /etc/debian_version) then

echo "Debian `cat /etc/debian_version`"

else if(-d /System/Library) then

set version_plist=System/Library/CoreServices/SystemVersion.plist

foreach vol (/Volumes/*)

if(-r "$vol/$version_plist") then

set name=`defaults read "$vol/${version_plist:r}" ProductName`

set build=`defaults read "$vol/${version_plist:r}" ProductBuildVersion`

set version=`defaults read "$vol/${version_plist:r}" ProductUserVisibleVersion`

printf "%-16s %10s %-10s %10s\n" "${vol:t}" "$name" "$version" "(build $build)"

endif

end

else

uname -s -r

endif

rpm -qf /etc/*-release

Comment by megacoder 243 weeks and 4 days ago

This is the best alternative, but it's not bullet proof. /etc/issue can be any custom message provided by the administrator. While it might work on home machines, or small business servers, it's unlikely to give you anything useful in schools, government organizations, large corporate enterprises, etc.

Fact of the matter is, when you're using an operating system, for whatever purpose, you should know what it is long before you start using it.

FYI.
