How to check quality of the Cisco IOS and CatOS configuration backup

One of the easiest ways to check Cisco configuration file quality is using shell script.
Our script will parse output to see if the following keywords are in the configuration file: "version", "show running-config", "begin", and "end".
If not all of the keywords found, then it will print the name of the file.

#!/bin/bash
for TEMPFILE in *
do
 TEMPCOUNT=0
 egrep "^(version|#version)" $TEMPFILE > /dev/null
 RETVAL=$?
 [ $RETVAL -eq 0 ] && TEMPCOUNT=`expr $TEMPCOUNT + 1`
 egrep "^(show running-config|begin)" $TEMPFILE > /dev/null
 RETVAL=$?
 [ $RETVAL -eq 0 ] && TEMPCOUNT=`expr $TEMPCOUNT + 1`
 egrep "^(end)" $TEMPFILE > /dev/null
 RETVAL=$?
 [ $RETVAL -eq 0 ] && TEMPCOUNT=`expr $TEMPCOUNT + 1`
 if [ $TEMPCOUNT -ne 3 ]; then
  echo $TEMPFILE
 fi
done

In another example, we just look for "version" keyword.

#!/bin/bash
for TEMPFILE in *
do
 egrep "^(version|#version)" $TEMPFILE > /dev/null
 RETVAL=$?
 [ $RETVAL -eq 0 ] && echo Found sting in $TEMPFILE
 [ $RETVAL -ne 0 ] && echo No string found in $TEMPFILE
done
