Firstly does cron have your environment, a quick check is to source in the local profile for your user.

There are many ways of doing this we'd normally use a token file or the like.

Normally I would put a token in the last line of the log file or in a separate file, then check the token with the following script. You must remember to either create a new logfile or null the logfile at the begining of the first script and you should test that it has done so.

In the first file something like;

Code:
print "Completed Ok" >> ${logfile}

In the following script;

Code:
if
          tail -1 ${logfile} | grep "Completed Ok" | grep -v grep
                then
                      Do Your Bits Here!
                else
                      print "The Backup had a problem - please investigate." >> ${logfile}
fi

This is just one of many ways you could do this, this very simplistic and probably wouldn't be allowed in a production environment. Ensure that any tests that you write are suitable for purpose - key to any of them is testing the result and failing safe!

zgrep

ZGREP(1)						      General Commands Manual							  ZGREP(1)

NAME

       zgrep - search possibly compressed files for a regular expression

SYNOPSIS

       zgrep [ grep_options ] [ -e ] pattern filename...

DESCRIPTION

       Zgrep  invokes  grep  on  compressed  or  gzipped  files.   These  grep	options  will  cause  zgrep  to  terminate  with  an  error  code:
       (-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*).  All other options specified are passed directly to grep.  If no file is specified,  then  the
       standard input is decompressed if necessary and fed to grep.  Otherwise the given files are uncompressed if necessary and fed to grep.

       If the GREP environment variable is set, zgrep uses it as the grep program to be invoked.

EXIT CODE

       2 - An option that is not supported was specified.
