Well file contents are part of the mail body, so I dont think I have cron deamon needs any info like that.
Please find below the code am using to perform this activity
Shell Script Code
----------------
emailText=/tmp/msgTxt.log
echo "" > $emailText
echo "Log Report" >> $emailText
echo "" >> $emailText
cat `ls -1tr /home/testadmin/testdir/test.log* | tail -1` >> $emailText
RECIPIENTS=testadmin@info.com
SUBJECT="Log Report Generated on "`date +%d-%m-%Y`"
MAILFILE=$emailText
echo "Sending email..."
echo To: $RECIPIENTS > yy
echo From: "$machineName" >> yy
echo Subject: $SUBJECT >> yy
echo MIME-Version: 1.0 >> yy
echo "Content-Type: multipart/mixed; boundary=MC" >> yy
echo --MC>> yy
echo "Content-Transfer-Encoding: 7bit" >> yy
echo "Content-Type: text/plain; charset=ISO-8859-1" >> yy
cat $MAILFILE >> yy
/usr/lib/sendmail $RECIPIENTS < yy
rm yy
rm $emailText
echo "Done!"
exit 0
This is want is been done in the shell script.
When the script is executed manually I am getting corret mail with mail body containing the "test.log" contents. BUt when executed by a cron job, the email body is missing the test.log contents.
Please advice were am I wrong.
Thanks & Regards,
Anshul

cron
cron(8) System Manager's Manual cron(8) NAME
cron - The system clock daemon SYNOPSIS
/usr/sbin/cron DESCRIPTION
The cron daemon runs shell commands at specified dates and times. Commands that are to run according to a regular or periodic schedule are found within the crontab files. Commands that are to run once only are found within the at files. You submit crontab and at file entries by using the crontab and at commands. Because the cron process exits only when killed or when the system stops, only one cron daemon should exist on the system at any given time. Normally, you start the cron daemon from within a run command file. During process initialization and when cron detects a change, it examines the crontab and at files. This strategy reduces the overhead of checking for new or changed files at regularly scheduled intervals. The cron command creates a log of its activities. The cron daemon must be started from the system startup scripts because it must begin execution without a login user ID set. The cron daemon starts each job with the following process attributes stored with the job by the invoking process: Login user ID Effective and real user IDs Effective and real group IDs Supplementary groups It also establishes the following attributes from the authentication profile of the account associated with the login user ID of the invok- ing process: Audit control and disposition masks Kernel authorizations DIAGNOSTICS
The at and batch programs will refuse to accept jobs submitted from processes whose login user ID is different from the real user ID. FILES
Specifies the command path. Main cron directory Directory containing the crontab files. List of allowed users. List of denied users His- tory information for cron Queue description file for at, batch, and cron RELATED INFORMATION
Commands: at(1), crontab(1), rc0(8), rc2(8), rc3(8) Files: queuedefs(4) delim off cron(8)
