Explanation around "+r" in egrep

UNIX for Beginners Q & A
1

Hi,

Is anyone able to shed some light on "+r" ?

I know -r in grep refers to a recursive search - I am curious to know what +r specifies.

#show process pidin | utility egrep -e "[0-9]+r" count
2492

Thanks.

r -> just a char.
[0-9]+ -> extended regular expression matching number.

Can you show output of show process pidin , so we can see output before greping.

Hi Peasant,

Here's the original output.
So I take this to mean match lines containing one or more numbers followed by the character r?

#show processes pidin
