if statment issue on ext script

It probably does expand, but it's never set because *$IP* never matches any
of the regular expressions.  An *else* statement with an error message will
show this.  Alternatively, in the definition of* $MSG*, give *$HOST* a
default value that makes this condition clear: *${HOST:-none}*.

His script works fine and he is looking for help in finding out why the
one variable doesn't expand. Once that is answered I'm sure he would be
glad to hear about other scripting advice.

Thanks,
Jim

 What’s with all the echos?  They are unnecessary and could be causing
issues. The following works fine:


if [[ $IP =~ ^10.xxx.xxx.1[0-9]; then

     HOST=’server33.test.corp.local’

fi


$ IP=10.5.102.13

$ if [[ $IP =~ ^10.5.10[0-9].13 ]]; then

   echo "$IP is a match"

fi

10.5.102.13 is a match

$ if [[ $IP =~ ^10.5.102.1[0-9] ]]; then    echo "$IP is a match"; fi

10.5.102.13 is a match

$ if [[ $IP =~ ^10.5.102.2[0-9] ]]; then    echo "$IP is a match"; fi

Sorry about that.

The issue is that $HOST is not printed in the output next to SERVER.


$BBHOME/bin/bbhostgrep $TESTNAME | while read IP HOSTNAME OTHER; do

  if do_fetch $HOSTNAME $IP | grep "$REGEX" > /dev/null ; then


if [[ `echo "$IP"` =~ ^10.xxx.xxx.1[0-9] ]]; then

HOST=`echo "server33.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.2[0-9] ]]; then

HOST=`echo "server34.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.3[0-9] ]]; then

HOST=`echo "server35.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.4[0-9] ]]; then

HOST=`echo "server36.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.5[0-9] ]]; then

HOST=`echo "server37.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.6[0-9] ]]; then

HOST=`echo "server38.test.corp.local"`


elif [[ `echo "$IP"` =~ ^10.xxx.xxx.7[0-9] ]]; then

HOST=`echo "server39.test.corp.local"`

fi


if [ $(echo "$X < 10" | bc) -ne 0 ]; then

            COL=green

            MSG="

Why is there more to your MSG than what is in your script?
