I work in a closed network and we can not just add software to the boxes.  I can however add a bash script.  

We need to store network information for all reasons, rebuild, move, desaster recovery etc.

Can anybody suggest commands they like that work on redhat 5 that are not on the list ?/
#! /bin/bash

hostname=${HOSTNAME}
output=output.txt

#########
#       The purpose of this function it to recive a shell command string (SS)
#       Echo a begin marker with hostname and (SS)
#       Echo the results of (SS)
#       Echo a end marker just like the start marker
#       except the begin marker has "b" and the end has "e"
#
#########



# clear out old output.txt
echo > ${output}

function doo(){

echo "tqf####~"$hostname"~${1}~b~####" >> ${output}
echo  >> ${output}

${1}  >> ${output}

echo  >> ${output}
echo "tqf####~"$hostname"~${1}~e~####" >> ${output}
echo  >> ${output}

}

## note all commands commented out were try and did not work on REDHAT 5.5.  
## most of the commented out commands are likely for solaris or software I do not have on my redhat 5.5 system

Hi there,

Looks like you are going for a *lot* of information there. I guess you need as much as you can for DR purposes, so I won't question what you will or won't need.  But, if you do have a question about info that may be superfluous, please ask. (like cat /etc/services)

Some of the ones I use a lot and don't see there:

  lsmod = shows loaded kernel modules (helpful with hardware drivers)
  lspci = shows PCI devices (also helpful w/ hardware)
  cat /proc/meminfo = memory info
  netstat -nr = configured IP routes
 
I noticed that some lines may be redundant:
Line 91,92: ls will only list the current directory you are in (or running the script from)
Line 101-103:  You get all you need with uname -a

Hope this helps!
