How to write this SIMPLE SCRIPT based on output to send mail ?

manalisharmabe · 04-14-2014, 06:22 AM

Hi Guys,

I am not Good at scripting.

I need to write a script such that if output of command shows the particular word in output then send mail to abc@compay.com

Code:

-bash-3.2$ ps -ef | grep bpbkar
    root  6040     1   0 13:05:19 ?           0:00 bpbkar -r 2678400 -ru root -dt 47395 -to 0 -clnt server1-backup-class server1
    root  6707     1   0 13:05:22 ?           0:00 bpbkar -r 2678400 -ru root -dt 47401 -to 0 -clnt server1-backup-class server1
    root  6302     1   2 13:05:20 ?           0:07 bpbkar -r 2678400 -ru root -dt 47403 -to 0 -clnt server1-backup-class server1
    root  5869     1   1 13:05:19 ?           0:05 bpbkar -r 2678400 -ru root -dt 47393 -to 0 -clnt server1-backup-class server1
    root  6493     1   2 13:05:21 ?           0:08 bpbkar -r 2678400 -ru root -dt 47402 -to 0 -clnt server1-backup-class server1
user1  9186 19295   0 13:05:33 pts/22      0:00 grep bpbkar
-bash-3.2$

in above output if the word server1-backup appears in the out put then it should send mail to abc@company.com that the "Server1 backup still running!"

This is Solaris 10 OS.

Please advise.

Thanks,
Manali.

I need to make script for following thing:-

if "ps -ef | grep bpbkar" shows server1-backup in output then send mail to abc@company.com

Code:

/usr/bin/mailx -r abc@company.com  -s "Server1 backup still runing!"

I need to send mail like above.

Thanks a lot for replying

use pgrep -f <pattern> && mailx ...

lordadamson · 04-15-2014, 12:21 AM

not sure if i understand you but try this

Code:

ps -ef | grep -q server1-backup && /usr/bin/mailx -r abc@company.com -s "Server1 backup still runing!"

lordadamson · 04-15-2014, 12:37 AM

well that line I just wrote won't work, it will always be true

but I believe pan64's will work just fine

Something like this?

Code:

      1 #!/bin/bash
      2 
      3 if ps -ef | grep -q $1 ; then
      4         mailx -r abc@company.com -s "$1 is running."
      5 else
      6         mailx -r abc@company.com -s "$1 is not running, attention is required."
      7 fi

manalisharmabe · 04-15-2014, 03:48 AM

or this?

Code:

cat check_backup

#!/bin/bash
# Script to check if Server1 backups still running.

if [ `ps -ef | grep bpbkar | nawk '{print gsub(/server1-backup/," ",$0)}'` -eq 1 ]
then
mailx -s "Server1 backup still running!" -r abc@company.com
fi

Thanks for replies.

pan64 · 04-15-2014, 03:57 AM

Code:

if [ `ps -ef | grep bpbkar | nawk '{print gsub(/server1-backup/," ",$0)}'` -eq 1 ]

as I told a pgrep would be much simpler. I'm not really sure this if [ ps|grep|nawk ] will work in every possible case.

manalisharmabe · 04-15-2014, 04:42 AM

Thanks for reply.

Please recorrect the script then, I am not good at this. I got it from google. :-)

pan64 · 04-15-2014, 04:47 AM

you would need to practice a bit, that would not be that hard at all:

Code:

pgrep -f <pattern> && mailx ...

the mailx command is already ok I think, you only need to find out the pattern.
pattern can be something like: 'root.*bpbkar.*server1'

manalisharmabe · 04-16-2014, 05:55 AM

Code:

The flags you gave are used only when sending mail.
Usage: mailx -eiIUdFntBNHvV~ -T FILE -u USER -h hops -r address
                -s SUBJECT -f FILE users

I got above Error for below script.

Code:

]#!/bin/bash

# Script to check if Server1 backups still running.

if [ `ps -ef | grep bpbkar | nawk '{print gsub(/server1-backup/," ",$0)}'` -eq 1 ]

then

mailx -s "Server1 backup still running!" -r abc@company.com

else

mailx -s "Server1 backup Completed!" -r abc@company.com

fi

however below script does not send any error:-

Code:

cat check_backup

#!/bin/bash
# Script to check if Server1 backups still running.

if [ `ps -ef | grep bpbkar | nawk '{print gsub(/server1-backup/," ",$0)}'` -eq 1 ]
then
mailx -s "Server1 backup still running!" -r abc@company.com
fi

chrism01 · 04-16-2014, 06:18 AM

You've got an extra character at the start of the first one

Code:

]#!/bin/bash

I also recommend using the 'set' debug cmd as the 2nd line thus

Code:

#!/bin/bash
set -xv

I used this script I got below Error:-

Code:

-bash-3.2$ cat server1-weekly_2nd
#!/bin/bash
# Script to check if SERVER1 Weekly Backups still running at 5 A.M. CET.
if ps -ef | grep server1-backup ; then
mailx -r  abc@company.com -s "SERVER1 Weekly Backup still running!"
else
mailx -r abc@company.com -s "SERVER1 Weekly Backup COMPLETED!"
fi

-bash-3.2$

I got below error:-

you ought read the man page of mailx about its flags and usage. the message you got means the command you tried to execute is not correct.
