Solaris

Hi,

I have a log file that i'd like to monitor for a string. Now the log file rolls over everytime the server is restarted, so i'm doing a reverse list and then reading the latest log file.

So for the code, the log file is 'test1.txt'.

I check for the string and pipe to black hole (> /dev/null)....and if this is true, I do the same again but this time I mail a message to the support team.

If this is false (||) I email to support team that no entry is found.

So far my code is:

Code:

#!/usr/bin/bash

set -- $(ls -r test1.txt) ; grep -i 'STRING_I_NEED_TO_FIND' $1 > /dev/null &&
set -- $(ls -r test1.txt) ; grep -i 'STRING_I_NEED_TO_FIND' $1 | 
mailx -r server@org.com -s "Error Message found on server $HOSTNAME, please investigate" my_email@whatever.com 
|| mailx -r server@org.com -s  "Error not found" my_email@whatever.com

when i have entered dummy error messages into my dummy file (test1.txt) i get them emailed to me.

however, my problem is that even if my dummy 'test1.txt' is blank, i still get a message saying that the error has been found and to investigate.

any help greatly appreciated.

thanks

Try this:

Code:

#!/usr/bin/bash

set -- $(ls -r test1.txt) 
grep -iq 'STRING_I_NEED_TO_FIND' $1 
if [ $? -eq 0 ] ; then
   mailx -r server@org.com -s "Error Message found on server $HOSTNAME, please investigate" my_email@whatever.com 
else   
  mailx -r server@org.com -s  "Error not found" my_email@whatever.com
fi

hi this doesnt seem to work for me. also i cannot use the 'q' in grep.

thanks anyhow
