Full Discussion: Grep a pattern and print following n lines
Operating Systems AIX Grep a pattern and print following n lines Post 302934458 by MadeInGermany on Saturday 7th of February 2015 10:19:59 AM

Problem solved. But the previous sed solution needs a fix; (at least on Solaris) it does not print at the end of a file, because the N command terminates the script. Therefore, each N is to be preceded by a $p.
The following works with a number for the trailing lines (here: 3).
Code:
sed -e '/^<search-pattern>/!d;:L' -e '$p;N;s/\n/&/3;t' -e 'bL' file

Hmm interesting, GNU sed prints at the end of the file, so the $p would print twice...
Which sed is correct?

zfgrep

ZGREP(1)						    BSD General Commands Manual 						  ZGREP(1)

NAME

     zgrep, zegrep, zfgrep -- print lines matching a pattern in gzip-compressed files

SYNOPSIS

     zgrep [grep-flags] [--] pattern [files ...]

     zegrep [grep-flags] [--] pattern [file ...]

     zfgrep [grep-flags] [--] pattern [file ...]

DESCRIPTION

     zgrep runs grep(1) on files or stdin, if no files argument is given, after decompressing them with zcat(1).

     The grep-flags and pattern arguments are passed on to grep(1).  If an -e flag is found in the grep-flags, zgrep will not look for a pattern
     argument.

     zegrep calls egrep(1), while zfgrep calls fgrep(1).

EXIT STATUS

     In case of missing arguments or missing pattern, 1 will be returned, otherwise 0.

SEE ALSO

     egrep(1), fgrep(1), grep(1), gzip(1), zcat(1)
