I added the color snippet, but only the red works on the failed pings (no green for the good pings). Is there a way to make the good pings green and the bad ones red? Have played around with the code and only get one color to show, either on the bad or good pings, but not both. Seems that the last argument is the only one to read the color code?

#!/bin/ksh

hosts='/etc/hosts'

while read ip host theRest
do
ping "${ip}" 1>/dev/null 2>&1
[[ "${?}" -eq 0 ]] && echo "${ip} is alive ${host} ${theRest}" || echo "${ip} IS DEAD!!! ${host} ${theRest}"
sed 's/.*IS DEAD!!!.*/[31;2m[0m/;s/.*is alive.*/[32;1m&[0m/'


done < "${hosts}"

Again, TIA.

debugreiserfs

DEBUGREISERFS(8)					      System Manager's Manual						  DEBUGREISERFS(8)

NAME

       debugreiserfs

SYNOPSIS

       debugreiserfs [ -dDJmoqpS ] [ -j device ] [ -B blocknumber ]

       device

DESCRIPTION

       It helps sometimes to solve problems with reiserfs filesystems. Being called w/o options it prints super block of reiserfs filesystem found
       on the device.

       device is the special file corresponding to the device (e.g /dev/hdXX for IDE disk partition or /dev/sdXX for SCSI disk partition).

OPTIONS

       -j device
	      print contents of journal. Also with the option -p it allows to pack journal into archive with other metadata

       -J     print journal header.

       -d     print formatted nodes of the internal tree of the filesystem

       -D     print formatted nodes of all used blocks of the filesystem

       -m     print contents of bitmap (not very useful)

       -o     print objectid map (not very useful)

       -1 blocknumber
	      print specified block of the filesystem

       -p     Makes debugreiserfs to find filesystem metadata This option exists to help reiserfsck debugging.	If  reiserfsck	fails  -  you  may
	      extract  filesystem metadata with debugreiserfs -p /dev/xxx |gzip -c > xxx.gz. We download that data and make the filesystem similar
	      to your with gunzip -c xxx.gz | unpack /dev/xxx (unpack is included into reiserfsprogs package). This usually  allows  to  reproduce
	      and debug the problem quickly. When data file is not too large.

       -S     When  -S	is not specified -p deals with blocks marked used in the filesystem bitmap. With this option set they will work with whole
	      device.

       -q     Suppress showing speed of progress when -p is in use
