[SOLVED] finding the process of each line in text file

Madhu Desai · 08-28-2014, 11:29 AM

Those listings are folders!!!

What I understand is - there are process running which have the same name as of the folder name. In that case instead of iterating through files, do it on folders.

This will check for folders:

Code:

#!/bin/bash
#Script: test.sh

apps=/opt/apache/qwest/websites/*/

for dir in $apps ; do
  trim1=${dir%/*}
  trim2=${trim1##*/}
  if pgrep $trim2 > /dev/null ; then
    echo "$trim2: Process is running"
  else
    echo "$trim2: No such process"
 fi
done

Seems like pgrep command is not working, I have tried giving the command directly , it's not listing any process.

because of that getting below output all the time.

aa99036-eap-int1-30101-40086: No such process
ace-30115-40102: No such process
ace-voip-30107-40097: No such process
amrtws-int1-30109-40095: No such process
aqcb-40015: No such process
armordev1-smx-30108-40094: No such process
armordev2-smx-30116-40103: No such process

if the name of the program (not directory) is watchdog what does this yield:

Code:

ps auxw | grep somak-30135-40122/watchdog

#!/bin/bash
#
#MailList=saicharan.burle@gmail.com
Distro_server=qtdenvmdt066
apps=/opt/apache/qwest/websites
cd $apps
###### This will print list of all applications into one txt file######
ls > print.txt

for username in `awk -F: '{print $1}' /opt/apache/qwest/websites/print.txt`
do
echo "Username $((i++)) : $username"
#pr=`ps -ef | grep $username|grep -v 'grep'|head -1|cut -d' ' -f6`
pr=`ps auxw | grep $username| grep -v grep | head -1| awk '{print $2}'`
echo " $pr "

if [ $pr > 0 ]
then
echo " $apps has been started successfully

"
else
echo " $apps has not started Please check......." |mailx -s "Health Check for $Distro_server" saicharan.burle@gmail.com
fi
done

The command worked, I just did some changes, This is the modified script which is working now.....

Please find the output:

Username 1 : aa99036-eap-int1-30101-40086

test.sh: line 21: mailx: command not found
Username 2 : ace-30115-40102
29868
/opt/apache/qwest/websites has been started successfully

Username 3 : ace-voip-30107-40097
3478
/opt/apache/qwest/websites has been started successfully

Username 4 : amrtws-int1-30109-40095
4397
/opt/apache/qwest/websites has been started successfully

Username 5 : aqcb-40015
4774

The only thing left is mailx command

schneidz · 08-28-2014, 12:52 PM

Saicharan Burle · 08-28-2014, 12:56 PM

echo " $apps has not started Please check......." |mail -s "Health Check for $Distro_server" saicharan.burle@gmail.com < /dev/null

Username 1 : aa99036-eap-int1-30101-40086

Null message body; hope that's ok

Seems like mailx will not work in Bash, with mail it is working, Can you just filter the above command, I am getting an email now but the body is not displaying, moreover if you see one of the application output which is down showing as Null message body

schneidz · 08-28-2014, 06:10 PM

mailx is probably not installed.

if you don't want null input then why are you redirecting /dev/null to the mail command ?
