Using SED to get n chars after given value from file
Hello, my name is Marc, I'm a linux starter
and I hope you specialists can help me solving this issue.
I have a file containing a lot of data. Somewhere in this file, there's a string called "Faultdump", directly followed by 64 chars of HEX data. I need to get the HEX part. I accomplished this with several lines of code in a script calling sed, cut as well as head/tail. I know some of you guys will manage to get this on one line by using just awk or sed by avoiding cat or head/tail. Please can anyone of you point me to the right direction?
I was searching through the forums, but I'm afraid, I couldn't find an appropriate example.
Many thanks in advance!
Marc (Kally).

zziplib-bin
ZZIPLIB-BIN(1) General Commands Manual ZZIPLIB-BIN(1)
NAME
zzcat, zzdir, zzxorcat, zzxordir zzxorcopy - small tools using zziplib
SYNOPSIS
zzcat FILE [...] zzdir DIR [...] zzxorcat [-HEX] FILE [...] zzxordir [-HEX] DIR [...] zzxorcopy [-HEX] FILE OUTFILE
DESCRIPTION
zzcat prints the given files to stdout, so you may want to redirect the output. The FILE can be a normal file or an inflated part of a zip
archive (see OPTIONS).
zzdir prints the content table to stdout of the given DIR or zipfile.
zzxorcat prints the given files to stdout, so you may want to redirect the output. The FILE is an inflated part of a zip archive
obfusctated with a xor value optionally given by the HEX option.
zzxordir prints the content table to stdout of the given DIR or zipfile. The DIR can br an inflated part of a zip archive obfusctated with
a xor value optionally given by the HEX option.
zzxorcopy copies data from FILE to OUTFILE adding simple obfuscation by xor-ing each byte with the HEX value given. Remember that copying
data twice with the same xor-value will result in the original file data.
OPTIONS
zziplib-bin tools accept the following options:
FILE Input filename for reading or part (if supported by tool). Part is written as zipname/filename, e.g.: for accessing README inside
of data.zip you'll specify data/README.
DIR Disk directory, zipfile or inflated part of a zipfile.
-HEX Hex number for xor-ing the zipfile contents. If not supplied all tools that use it take 0x55 as default value for xor-ing. OUTFILE
Output file name for zzxorcopy.
