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)

dijkstra
DIJKSTRA(1) General Commands Manual DIJKSTRA(1)NAME
dijkstra - single-source distance filter
SYNOPSIS
dijkstra [ -ap? ] [ sourcenode file ]
DESCRIPTION
dijkstra reads a stream of graphs and for each computes the distance of every node from sourcenode. Edge length is given in the len
attribute, and the default is 1. The dist attribute of every node is set to its distance from sourcenode. If the -p flag is used, the
prev attribute of each node reachable from sourcenode is set to the name of the previous node on a shortest path. The graph attribute
maxdist is set to the maximum dist of all nodes in the graph.
By default, if the graph is disconnected, the dist attribute of nodes unreachable from sourcenode are left untouched, and maxdist is set to
the maximum of any previous value and the largest distance recorded in this run. On the other hand, if the -a flag is used, the dist
attribute of an unreachable node is assigned a very large value, and maxdist records the maximum distance found in the component containing
sourcenode.
Any number of sourcenode file pairs may be given. If the last file is missing, stdin is used. All output is written to stdout.
In a typical application, dist and maxdist can drive a downstream calculation of color or some other attribute.
