Well I have several text files with different names. The content of these files is diverse, but they all usually include a field with sender of an email, subject of email, date...
But then there are more lines that are less important.
My purpose is to move the lines I am interested in to the top of each file, and leave the rest below. Basically remove some cruft from each of the files using grep/sed...
I don't know how to accomplish this with all the files in the folder, as they have different names. Plus the resulting files of the process should have the initial name plus some kind of suffix (Example: original name 175.txt, after process 175_1.txt)
As you can see my command includes several steps, and maybe more steps in the future (file 175.txt > 175_1.txt > 175_2.txt...)
Thanks for the help!

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.
