I've been looking through the forums for awhile now and looking at the man page for grep and egrep and not seeming to find this scenario so it might not be possible but figured I'd throw it out to get some ideas.
I'm looking for a way to search a file for 1st match (example below net self) and end search when it runs into 2nd match (example below } character) and output those results. Eventually I will want to edit those lines (either delete each line OR replace matching IP Address)
Since I'm far from being knowledgeable but love to learn I have tried what I do know which includes some awful ideas like

Hi,
I'm struggling with a regex that would match a 'b' that follows an 'a' and is at the end of a string of non-white characters. For example:
Line 1: aba abab b abb aab bab baa

Both these methods require that I use the escape character. I am guessing that is why... (8 Replies)

zgrep
ZGREP(1) General Commands Manual ZGREP(1)NAME
zgrep - search possibly compressed files for a regular expression
SYNOPSIS
zgrep [ grep_options ] [ -e ] pattern filename...
DESCRIPTION
Zgrep is used to invoke the grep on compress'ed or gzip'ed files. All options specified are passed directly to grep. If no file is speci-
fied, then the standard input is decompressed if necessary and fed to grep. Otherwise the given files are uncompressed if necessary and
fed to grep.
If zgrep is invoked as zegrep or zfgrep then egrep or fgrep is used instead of grep. If the GREP environment variable is set, zgrep uses
it as the grep program to be invoked. For example:
for sh: GREP=fgrep zgrep string files
for csh: (setenv GREP fgrep; zgrep string files)
