Parsing a $VARIABLE within a script.

Parsing a $VARIABLE within a script.
Hello all,
I have a situation where I need to parse for certain items from a $VARIABLE within a sh script.
The line inside the sh script where this takes place is simply an echo:
echo "EventMessage: $EVENTMSG"
Is there a way to parse the $EVENTMSG by using RegEx? AND can I put the results of the RegEx as another variable WITHIN the same script?
I have a situation where I need to parse for certain items from a $VARIABLE within a sh script.
- The sh script is run when an alert comes in.
- The alert data payload has a Message field called "EVENTMSG"
- The script that is run takes the "EVENTMSG" and prints it out to the ticket.
- I need to parse the "EVENTMSG" for additional information.
echo "EventMessage: $EVENTMSG"
Is there a way to parse the $EVENTMSG by using RegEx? AND can I put the results of the RegEx as another variable WITHIN the same script?
| My desired output is something like this: |
| (within the script) |
| blah blah blah... |
| echo "EventMessage: $EVENTMSG" |
| SEV=".+AlarmSeverity=\s(\S+).+" ((where $SEV is taken somehow from within the $EVENTMSG)) |
|
| MANY THANKS IN ADVANCE!!! |
