Probably I was not clear enough:

I need to extract X lines after the Nth occurrence of a pattern.

The patter cointains '/' character this gave probably problem on sed.

something like

1/1/1/1
qweqw
qweqw
qweqe
1/1/1/1
qewq
qewq
1/1/1/1
qwe
1/1/1/1
1/1/1/1
To get the 2 lines after the 2nd match of the pattern "1/1/1/1":

Code:
awk '/1\/1\/1\/1/ && ++c==2{p=2;next}p-->0' file

XDRIVER_WINDOW ? XDRIVER_PRIVATE_CMAP Private color map (?) XDRIVER_LEFT defines the left position of GRASS monitor (removed?) XDRIVER_TOP define the upper position of GRASS monitor (removed?) Set the XDRIVER size # bash shell syntax: export GRASS_WIDTH=xxx export GRASS_HEIGHT=yyy # c shell syntax: setenv GRASS_WIDTH xxx setenv GRASS_HEIGHT yyy To control the XDRIVER, use the d.mon module. The maximum color depth depends on the current X Server settings. SEE ALSO
