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!

cachefslog

cachefslog(1M)															    cachefslog(1M)

NAME

       cachefslog - Cache File System logging

SYNOPSIS

       logfile| cachefs_mount_point

DESCRIPTION

       The  command is used to enable or disable logging for a cachefs_mount_point.  When the command is used without any options, it displays the
       logfile.  The logfile contains information on the operation performed on a cachefs_mount_point and statistics used by to  get  the  working
       set  size  of cache directory.  The specified logfile will contain information for all the CacheFS mount points using the same cache direc-
       tory.  A logfile and a cache directory have a 1-to-1 mapping; that is, even if a cache directory is removed and	recreated  with  the  same
       name, the logfile used in the previous instance of the cache directory cannot be reused with the new cache directory.

       Enabling  logging  may  have  performance  impact, even if minimal, on the operations for all the CacheFS mount points using the same cache
       directory.  The command is mainly used for debugging purposes.

   Options
       The following options are supported.  You must be a superuser to use the and options.

       Specify the logfile to be used.

       Halt logging.

   Operands
       cachefs_mount_point
		      A mount point of a cache file system.

RETURN VALUE

       returns the following values:

	      Success.

	      non-zero	An error occurred.
