How to perform Grep on many Gzip files, Searching for Specific information
Hello,
I am wondering if you can assist with my question and ask kindly for this.
I have a number of files that are listed as file1.gz through file100.gz.
I am trying to perform a grep on the files and find a specific date that only resides within within one of the files. There are multiple entries within the file so I am try to also limit the amount of output with the tail or head command.
My command is something like this, although it is incorrect:
gunzip -c file1.*.gz |grep -v "Jul 25 22:16:09" | tail -n 20
Thank you kindly.

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 invokes grep on compressed or gzipped files. These grep options will cause zgrep to terminate with an error code:
(-[drRzZ]|--di*|--exc*|--inc*|--rec*|--nu*). All other options specified are passed directly to grep. If no file is specified, 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 the GREP environment variable is set, zgrep uses it as the grep program to be invoked.
EXIT CODE
2 - An option that is not supported was specified.
