search in multiple compressed files with zgrep

zgrep_search.sh

#!/bin/bash
# grep over several zipped files
# in this case with with two search words "SEARCH1" OR "SEARCH2"
# it will also sort the entries and open them in "less" to view as a document
zgrep "SEARCH1\|SEARCH2" /application/logs/2019/03/app_*17.03.30*.gz|cut -d : -f 2-|sort --stable --key 1,1 |less

# E.G. search for "Exception
zgrep "Exception" /application/logs/2019/03/app_*17.05.*.gz|cut -d : -f 2-|sort --stable --key 1,1 |less

# to count the output lines, add following pipe at the end, instead of | less 
| wc -l

# HowTo search in multiple gzip files without extracting them:
find . -name "*.gz" -exec zgrep 'PATTERN-TO-LOOK-FOR' {} \;

zgrep -iHn -B 20 -A 10 'PATTERN-TO-LOOK-FOR' $LOGFILE

# This command looks for every file with the pattern *.gz. For every file it’ll execute the zgrep command and looking for the "PATTERN-TO-LOOK-FOR“.
