___________________________
Here is the script I executed.

#!/bin/sh

logFile=~/AppInstance_status.txt

#store in a variable; easier to maintain

AppInstance=(xxx,aaa,ddd,ccc,xxx,cccfg)

for i in "${AppInstance[@]}" ;
do
AppInstance_status=`ps -ef | grep $i | grep -v grep`

if [ -z "$AppInstance_status" ] ;
then
echo "App Instance $i is not running . $(hostname) as on $(date)" >> $logFile
fi
done

cat $logFile | mail -s "Alert: AppInstance status check on Production " xxxx@xxxx.com

The AppInstance_status.txt file is under the home directory at the same location where I run the scripts.

example: /home/xxx/scripts/AppInstance_status.txt

but it is trying to read from /home/xxx/AppInstance_status.txt. Do I need to change any where the location of the file? What I want it to do is to look for that txt file and run all 40 instances from the file and give the results if any of the instance is down.

It is too complicated but I badly need help in this script.

Please help and again thanks in advance.

I got the txt file moved to one upper level and my code started working but have a question to rectify it.

I want the txt file to display only the instances that are under stop status and not all the instances. Right now, it displays whatever in the txt without executing the command.

Can anyone help please.

gensprep(8)							 ICU 50.1.2 Manual						       gensprep(8)

NAME
gensprep - compile StringPrep data from files filtered by filterRFC3454.pl SYNOPSIS
gensprep [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright ] [ -s, --sourcedir source ] [ -d, --destdir destination ] DESCRIPTION
gensprep reads filtered RFC 3454 files and compiles their information into a binary form. The resulting file, <name>.icu, can then be read directly by ICU, or used by pkgdata(8) for incorporation into a larger archive or library. The files read by gensprep are described in the FILES section. OPTIONS
-h, -?, --help Print help about usage and exit. -v, --verbose Display extra informative messages during execution. -c, --copyright Include a copyright notice into the binary data. -s, --sourcedir source Set the source directory to source. The default source directory is specified by the environment variable ICU_DATA. -d, --destdir destination Set the destination directory to destination. The default destination directory is specified by the environment variable ICU_DATA. ENVIRONMENT
ICU_DATA Specifies the directory containing ICU data. Defaults to /usr/share/icu/50.1.2/. Some tools in ICU depend on the presence of the trailing slash. It is thus important to make sure that it is present if ICU_DATA is set. FILES
The following files are read by gensprep and are looked for in the source /misc for rfc3454_*.txt files and in source /unidata for Normal- izationCorrections.txt. rfc3453_A_1.txt Contains the list of unassigned codepoints in Unicode version 3.2.0.... rfc3454_B_1.txt Contains the list of code points that are commonly mapped to nothing.... rfc3454_B_2.txt Contains the list of mappings for casefolding of code points when Normalization form NFKC is specified.... rfc3454_C_X.txt Contains the list of code points that are prohibited for IDNA. NormalizationCorrections.txt Contains the list of code points whose normalization has changed since Unicode Version 3.2.0. VERSION
