[SOLVED] script to send email after 7 days of remainder

Yup. Again: Read the man page for at on your system. Figure out what the errors mean.
I'm out.

below script created by me for below purpose,
1. If Server mentioned in server.txt is up from 7 days then email should sent to a person.
2. Server name should mention in email subject.
3. it should run every day at particular time.

Quote:

#/bin/bash
for i in `cat /tmp/script/server.txt`
do
t=`ssh -q $i "uptime" | cut -d" " -f6`
if [ $t > 7 ]
then
echo "don't forget whatever you wanted to do" > file-containing-reminder-text
#at now+7days <<END
/usr/bin/mailx -s $i_reminder rockstar05@gmail.com <file-containing-reminder-text
fi
done

after execution got below message,

Quote:

The flags you gave are used only when sending mail.

Suggestion/modification welcomes.

Awaiting for reply,

Thanks

Thanks,

You just said you had it working with the '-r' flag, and have been given MANY suggestions/remarks thus far. Better question is what happens when you actually try to run the script, now that you have read the man page on the mailx command for HP/UX?

it works fine ...!!!

But I wanted to make much better script which will not fail in any condition.

Now, 2nd time it failed,

Quote:

for i in `cat /tmp/script/server.txt`
do
# t=`ssh -q $i "uptime" | cut -d" " -f6`
if [ `ssh -q $i "uptime" | cut -d" " -f6` > 7 ]
then
echo "don't forget whatever you wanted to do" > file-containing-reminder-text
/usr/bin/mailx -s `$i`_reminder -r rockstar05@gmail.com <file-containing-reminder-text
fi
done
+ cat /tmp/script/server.txt
+ cut -d -f6
+ ssh -q PEPSI uptime
+ [ 319 ]
+ 1> 7
+ echo don't forget whatever you wanted to do
+ 1> file-containing-reminder-text
+ PEPSI
./mail1.sh[9]: PEPSI: not found.
+ /usr/bin/mailx -s _reminder -r rockstar05@gmail.com
+ 0< file-containing-reminder-text
The flags you gave are used only when sending mail.

The only difference I put first time I put 2 servers in /tmp/script/server.txt, and 2nd time I put 1 server.

is there anything wrong ?

The HP-UX man page

Code:

man at

describes the possible formats, and gives the following examples

Code:

...
           at 0815 Jan 24
           at 8:15 Jan 24
           at 9:30am tomorrow
           at now + 1 day
           at -f job 5 pm Friday
...

It needes spaces between words and values.
I see now, you are beyond that.
There is another error in your [ ] test:
the "greater than" operator is -gt (not > that is interpreted as a redirection to a file!)

Thanks MadeInGemany for feedback, I have corrected as much as I can. Now, below is the script.

Script,

Quote:

#/bin/bash
set -xv
for i in `cat /tmp/script/server.txt`
do
# t=`ssh -q $i "uptime" | cut -d" " -f6`
if [ `ssh -q $i "uptime" | cut -d" " -f6` -gt 7 ]
then
echo "don't forget whatever you wanted to do" > file-containing-reminder-text
/usr/bin/mailx -r rockstar05@gmail.com -s "`$i`_remainder" <file-containing-reminder-text
fi
done

Output,

Quote:

+ cat /tmp/script/server.txt
+ cut -d -f6
+ ssh -q pepsi uptime
+ [ 320 -gt 7 ]
+ echo don't forget whatever you wanted to do
+ 1> file-containing-reminder-text
+ pepsi
./mail1.sh[9]: pepsi: not found.
+ /usr/bin/mailx -s _reminder -r rockstar05@gmail.com
+ 0< file-containing-reminder-text
The flags you gave are used only when sending mail.

As per above output, I unable to fetch why again "./mail1.sh[9]

epsi: not found" coming. Also, lastly, "The flags you gave are used only when sending mail".

not sure, where I loss my eye in the script.

Thanks,

Don’t use backticks around the variable...makes it be interpreted as a command, which is then “not found”

Fix one error at a time. The debug output is showing you that the mailx command got broken up.

rockstar05 · 01-20-2020, 09:44 AM

Yeah corrected. replacing -r with -m.

rockstar05 · 01-21-2020, 02:19 AM

anything else ? I also wanted to add multiple email-ids who is in copy.

how can I add here in the same for loop ?

MadeInGermany · 01-27-2020, 01:12 AM

I think that mailx takes multiple mail addresses:

Code:

mailx -s subject a@b.com c@d.net

See its man page

Code:

man mailx
