Thanks to egrep
for linguists for giving this nice and clear example of using
egrep.
There are different ways to match both star and stars within a single
search pattern. The most straightforward way might be to tell egrep to
look for either the string star or the string stars with the help of a
disjunction, expressed with the vertical bar, |. This time the search
pattern has to be quoted in order for the program to know where the
search pattern starts and ends
$ egrep -w 'star|stars' sonnets.txt
Not from the stars do I my judgement pluck,
And constant stars in them I read such art
Whereon the stars in secret influence comment.
Let those who are in favour with their stars,
Till whatsoever star that guides my moving,
One of the details that emerged from Curt's monitoring of the Invita
Security network involved a password used by Alexey Ivanov. When
accessing one of his drop sites, Alexey's FTP password was
www.pidor.com (Internet Archive available). Think of what an unwary
analyst might do with that information. Only someone who is monitoring
Alexey's actions might know about www.pidor.com. Say that unwary
analyst decides to visit www.pidor.com to learn more about the
site. If Alexey or a friend is monitoring Web accesses to
www.pidor.com, they could learn that they are being monitored. This
case demonstrates how important it is for analysts to not "touch"
remote or foreign sites involved in intrusions. You may tip your hand
to the attacker and ruin an investigation or recovery effort.
