The thing is that sometimes I need to filter an arbitrary output given a condition (think on the "filter" function present on some programming languages) from the shell (I use sh/bash). I tried this:
#!/bin/sh
# Usage: filter command

I have been using unix on and off for a number of years. I am not a sys admin. I use what I need. I have googled this, but I really can't figure out what is the difference between using xarg and just using a regular pipe? Why do I need to include xarg sometimes and how do I know when I need it?

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 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.
