Re^3: grep -A10 oneliner?

The first is trivial: set the number to be the total number of context lines you want, including the matched pattern line.

The second is a little trickier:

perl -ne 'print if $.=/pattern/?1:2..10'
[download]

~~In this case, it will print 10 lines after the match.~~

Update: so tricky, in fact, that you can't do it with the range operator. So there's no point in using $.. So you just do

perl -ne 'print if$c=/pattern/?11:$c&&$c-1'
[download]

or any of the other solutions here. Sigh.
One that doesn't require you to add one to the number you put in:

perl -ne 'print if(/pattern/?$c=10:$c--)>0'
[download]
