Holy mother of pe(a)rl! Here's your solution on the half shell. Sorry
for the bad puns - I'll clam up now.
grep -P -i '^125.*?baxp\.caed.*?\n250'
Documentation:
http://www.gnu.org/software/grep/doc/grep_6.html#SEC6
from gnu's grep --help
-P, --perl-regexp PATTERN is a Perl regular expression
Basic info sheet on Gnu's Grep
http://www.gnu.org/software/grep/grep.html
Demo (on windows where I don't need to quote the pattern):
C:\tmp>cat foo
125asdfasdfbaxp.caedasdfasdf
250 eat my shorts
250 eat my shorts
250 eat my shorts
C:\tmp>grep -P -i ^125.*?baxp\.caed.*?\n250 foo
125asdfasdfbaxp.caedasdfasdf
250 eat my shorts
