Java Help with Shell Script
Hello Guys,

I want to write a shell script which monitors SystemOut.log file which goes on update.

This script must check the log file continuously and if any error with ORA- appears it must send the error and next 10 lines to an email, and if any new ORA- error comes again it must do the same.

Any one can help me?

TIA

Something like this perhaps.

Because of buffering, it may not email immediately when errors do. That's difficult to avoid. It will also wait for 10 full lines.
Code:
#!/bin/sh

tail -f SystemOut.log | while read LINE
do
        case "$LINE" in
        *ORA-*)
                cat <<EOF | sendmail
To: whoever
From: whoever
Subject:  $LINE

`head -n 10`
EOF
                ;;

        *)        ;;
        esac
done

Thank you so much for the reply but do we execute by the following way,

save the code in edit.sh file and run as sh edit.sh

is this the way or sh edit.sh SystemOut.log

I modified to this but still not working

Code:
#!/bin/sh

tail -f SystemOut.log | while read LINE
do
        case "$LINE" in
        *ORA-*)
                cat <<EOF | mailx -s "$LINE" xyz@yahoo.com

`head -n 10` 
EOF
                ;;
                  
        *)        ;;
        esac      
done

Try this:
Code:
#!/bin/sh

tail -f SystemOut.log | while read -r LINE
do
        case "$LINE" in
        *ORA-*)
                cat <<EOF | sendmail
To: whoever
From: whoever
Subject:  $LINE

`grep -A 10 -F "$LINE" SystemOut.log`
EOF
                ;;

        *)        ;;
        esac
done
