Grep file and include lines around search result

grep -A 1 -i "Search-for-something" /var/lib/jbossas/server/halprdjbs01/log/server.log

6.1 Display N lines after match

-A is the option which prints the specified N lines after the match as shown below.

Syntax:
grep -A <N> "string" FILENAME

The following example prints the matched line, along with the 3 lines after it.

$ grep -A 3 -i "example" demo_text

6.2 Display N lines before match

-B is the option which prints the specified N lines before the match.

Problem with Outlook on Mac Mail

Could not delete an email message.  I was actually already deleted but it kept showing up on mail and could not be deleted.  Solution was to rebuild the email.

"mailbox, rebuild" fixed the problem.
