regex - Windows equivalent to grep -B (before context) and -A (after context)? -

in grep understand there -b switch will...

print num lines of leading context before matching lines.

... example might run command like:

cvs log -n -s -w<userid> -d"1 day ago" | grep -b14 "some text" > afile 

is there equivalent in windows? i've got is:

cvs log -n -s -w<userid> -d"1 day ago" | find "7492" > output.txt 

but pipes text on same line 7492 in output, whereas need of preceding lines usefully interpret information. far can see find command doesn't have switch equivalent -b switch of grep. there way of replicating aspect of grep functionality in windows?

use select-string's -context argument. example:

git log | select-string limit -context 5,0 

this 5 line before, 0 lines after. example happens hash matches git commit message.

if enter 1 number value of parameter, number determines number of lines captured before , after match. if enter 2 numbers value, first number determines number of lines before match , second number determines number of lines after match.
