hey all....
I've been taking advantage of the shared rsa key that Ian set me up with
a while back for our 122 render nodes that allows me to ssh without a
pwd to those specific machines. The next step was to create a couple of
anyscript.sh shell scripts that basically do a given command on all of
them. for example ( and I know this is very basic so try not to laugh
too hard.....) -
#! /bin/sh
echo "attempting to ssh 192.168.3.2 as root"
ssh root@192.168.3.2 "df -h"
echo "attempting to ssh 192.168.3.3 as root"
ssh root@192.168.3.3 "df -h"
echo "attempting to ssh 192.168.3.4 as root"
ssh root@192.168.3.4 "df -h"
echo "attempting to ssh 192.168.3.5 as root"
ssh root@192.168.3.5 "df -h"
echo "attempting to ssh 192.168.3.6 as root"
ssh root@192.168.3.6 "df -h"
echo "attempting to ssh 192.168.3.7 as root"
ssh root@192.168.3.7 "df -h"
echo "attempting to ssh 192.168.3.8 as root"
ssh root@192.168.3.8 "df -h"
and so on all the way through .123 at the end. If I want to see
something else I just do a search and replace of whatever is in quotes.
While this gets the job done, I know that this way is not very efficient
and it will get worse as more nodes are added. In an effort to learn
more, can anybody tell me if there's a way to add a variable that
increases by a factor of 1 until it reaches a certain number (say
.123)?? If this could be done, I could just change the stop point for
the variable. In addition to this does anybody know where any good web
tutorials are for sh and bash scripting basics??
thanks!!
