Actually I have one more bug:


Any idea why we see the same DIFF_DATE syntax error in expr for this section:

Code:
while IFS=, read -r INSTANCE SESS_COUNT INSERT_TIME

DATE_DIFF=`expr ${CHECK_DATE_1} - ${INSERT_TIME}`

do

if  [[ ${SESS_COUNT} -eq 0 ]]
then
echo Send Normal Alert

elif [[ ${DATE_DIFF} -gt 300 && ${DATE_DIFF} -lt 600 ]]
then
echo Critical Alert: ${DATE_DIFF}

elif [[ ${DATE_DIFF} -gt 600 ]]
then
echo Major Alert: ${DATE_DIFF} ${INSTANCE}

fi
done < ${FILE1}


Code:
+ IFS=,
+ read -r INSTANCE SESS_COUNT INSERT_TIME
++ expr 1525273451 -
expr: syntax error
+ DATE_DIFF=


It seems to another read of the file at the end of the script even though there are no extra lines before the data or after the data in the file:

Code:
lit-dbracm01-p002:/home/oracle>cat /tmp/longrunmon.out
testinst,0,1525186184
testinst-2,0,1525186184

svn_checkout - Checks out a working copy from the repository

SYNOPSIS
bool svn_checkout (string $repos, string $targetpath, [int $revision], [int $flags]) DESCRIPTION
Checks out a working copy from the repository at $repos to $targetpath at revision $revision. PARAMETERS
o $repos - String URL path to directory in repository to check out. o $targetpath - String local path to directory to check out in to Note Relative paths will be resolved as if the current working directory was the one that contains the PHP binary. To use the calling script's working directory, use realpath(3) or dirname(__FILE__). o $revision - Integer revision number of repository to check out. Default is HEAD, the most recent revision. o $flags - Any combination of SVN_NON_RECURSIVE and SVN_IGNORE_EXTERNALS. RETURN VALUES
Returns TRUE on success or FALSE on failure. NOTES
Warning This function is EXPERIMENTAL. The behaviour of this function, its name, and surrounding documentation may change without notice in a future release of PHP. This function should be used at your own risk. EXAMPLES
Example #1 Basic example This example demonstrates how to check out a directory from a repository to a directory named calc: <?php svn_checkout('http://www.example.com/svnroot/calc/trunk', dirname(__FILE__) . '/calc'); ?> The dirname(__FILE__) call is necessary in order to convert the calc relative path into an absolute one. If calc exists, you can also use realpath(3) to retrieve an absolute path.
