Found this old thread while researching. I come up against this problem often in a very heterogeneous network I admin. Barring us deploying Puppet or a similar solution (someday), I need a fix. There is no canonical way to determine distro so this script is a hack around. It works (gives a best guess) on slack, suse, rh, centOS, ubuntu, solaris, and a couple of other proprietary systems we use.
Comment, suggest, port, test, change, flame.
Code:
#! /bin/bash
# return an awkable string consisting of
# unix OS type, or
# Linux dist, or
# a long guess (based on /proc), or
# no clue
giveUp () {
echo "Unknown"
exit 0
}
# keep this easily awkable, prepending an initial clue
versionGuess () {
if [ -e /proc/version ]; then
echo -n "Unsure "
cat /proc/version
exit 0
fi
return 1
}
# if we have ignition, print and exit
gotDist () {
[ -n "$1" ] && echo "$1" && exit 0
}
# we are only interested in a single word "dist" here
# various malformations can occur; admin will have to code appropately based on output
linuxRelease () {
if [ -r /etc/lsb-release ]; then
dist=$(grep 'DISTRIB_ID' /etc/lsb-release | sed 's/DISTRIB_ID=//' | head -1)
gotDist "$dist"
fi
dist=$(find /etc/ -maxdepth 1 -name '*release' 2> /dev/null | sed 's/\/etc\///' | sed 's/-release//' | head -1)
gotDist "$dist"
dist=$(find /etc/ -maxdepth 1 -name '*version' 2> /dev/null | sed 's/\/etc\///' | sed 's/-version//' | head -1)
gotDist "$dist"
return 1
}
# start with uname and branch the decision from there
dist=$(uname -s 2> /dev/null)
if [ "$dist" = "Linux" ]; then
linuxRelease
versionGuess
giveUp
elif [ -n "$dist" ]; then
echo "$dist"
exit 0
else
versionGuess
giveUp
fi
# we shouldn't get here
giveUp
# done
Hi,
I m working on many Linux servers in my project. But i am unable to know which Linux Distribution i am using Like whether i am using SUSE or REDHAT or MONDRAKE. I tried with "uname" command. But it does not help me. Please provide me the command if u know.

Hey
I am right now working on an old Compaq computer, and because I have a newer one I thought of installing Linux on this one. The thing is that I don't know which Linux distribution that would work with a minimum of lag. My computer specifications is:

Hi,
i'm currently part of an apprenticeship becoming a IT specialist.
Because I'm already an electronic technician (finished apprenticeship) I can do this one in 2 years (normally you need 3).
Thing is, in school they started out with basic unix stuff (working with the shell) in the first... (3 Replies)
What was the first Linux distribution you tried?
My first was Knoppix, it was pretty good I thought, and it supported my old hardware http://www.linuxforum.com/images/smilies/smile.png Too bad I couldn't figure out how to install it at the time though.
What about you? (32 Replies)

g_dist
g_dist(1) GROMACS suite, VERSION 4.5.4-dev-20110404-bc5695c g_dist(1)NAME
g_dist - calculates the distances between the centers of mass of two groups
VERSION 4.5.4-dev-20110404-bc5695c
SYNOPSIS
g_dist -f traj.xtc -s topol.tpr -n index.ndx -o dist.xvg -lt lifetime.xvg -[no]h -[no]version -nice int -b time -e time -dt time -xvg enum
-dist real
DESCRIPTION
g_dist can calculate the distance between the centers of mass of two groups of atoms as a function of time. The total distance and its
x-, y-, and z-components are plotted.
Or when -dist is set, print all the atoms in group 2 that are closer than a certain distance to the center of mass of group 1.
With options -lt and -dist the number of contacts of all atoms in group 2 that are closer than a certain distance to the center of mass
of group 1 are plotted as a function of the time that the contact was continuously present.
Other programs that calculate distances are g_mindist and g_bond.
