RE: I have a question involving some cron'd shell scripts and Redhat 7.0 performance / methodology / peer review

MessageEric,

I notice in all of your script examples that you don't load a script
interpreter in any of them.

I'm not exactly a script expert myself, but I do a LOT of Perl and a handful
of bash scripts and they all have to have

#!/bin/bash

or

#!/usr/bin/perl


 graph1 script

  CENTERS=$(cat /usr/local/rrdwork/graph_centers) #This is a list of all
current remote facilities, i.e. norda1 norda2
  for center in $CENTERS;do
  /usr/local/rrdwork/graph_hour $center >> /dev/null # these graph_*  files
are duplicates, with the only difference being the time ranges
  /usr/local/rrdwork/graph_day $center >> /dev/null
  /usr/local/rrdwork/graph_week $center >> /dev/null
  done
  exit 0

  updatec script example
  FACS=$(cat /usr/local/rrdwork/centers)         #the updatec2 script would
reference /usr/local/rrdwork/centers2, this is the only difference in these
scripts
  for fac in $FACS ;do                                    #so I have each
group of remote systems broken up into 4 centers* files.
  master=`rsh $fac /bin/totinf`
     ld=`echo "$master"|gawk '{ if (NR == 1) print $0 }'`
     users=`echo "$master"|gawk '{ if (NR == 2) print $0 }'`
     tout=`echo "$master"|gawk '{ if (NR == 3) print $0 }'`
     tout2=`echo "$master"|gawk '{ if (NR == 4) print $0 }'`
     dat=`date`
     systime=`echo "$master"|gawk '{ if (NR == 5) print $0 }'`
     cpu=`echo "$master"|gawk '{ if (NR == 6) print $0 }'`
     uptim=`echo "$master"|gawk '{if (NR == 7) print $0}'`
     cmv=`echo "$master"|gawk '{ if (NR == 8) print $0}'`
  rrdtool update /usr/local/rrdwork/rrds/$fac.rrd N:$ld:$users:$tout:$tout2
  if [ -e /usr/local/rrdwork/logs/$fac.log ] ; then >
/usr/local/rrdwork/logs/$fac.log; fi
  echo "$ld" >> /usr/local/rrdwork/logs/$fac.log
  echo "$users" >> /usr/local/rrdwork/logs/$fac.log
  echo "$tout" >> /usr/local/rrdwork/logs/$fac.log
  echo "$tout2" >> /usr/local/rrdwork/logs/$fac.log
  echo "$systime" >> /usr/local/rrdwork/logs/$fac.log
  echo "$cpu" >> /usr/local/rrdwork/logs/$fac.log
  echo "$uptim" >> /usr/local/rrdwork/logs/$fac.log
  echo "$cmv" >> /usr/local/rrdwork/logs/$fac.log
  done

  And finally, the remote script which is executed by the updatec series of
scripts.
