RegEx - selective delete around a pattern
I need RegEx to delete text block delimited by "^--" and "^request saved" if the block contained the pattern "FAILED:No air,rail,hotel or car" in the following.

Many thanks in advance!

Code:

How about the following awk one-liner:
Code:
awk '!/FAILED:No air,rail,hotel or car/{printf (N++?RS:"") $0}' RS="--\n" infile
