Hello John,
Thank you for guiding me. I used last 5 years (while being with INTEL)
mainly HxD (for WIN). Did not used very long hex editors for Linux. Here it
is (your suggestion):
_______
[zoran@localhost tools]$ dnf whatprovides hexedit
hexedit-1.2.13-8.fc24.x86_64 : A hexadecimal file viewer and editor
Repo : fedora
[root@localhost tools]$ sudo dnf install hexedit-1.2.13-8.fc24.x86_64
Last metadata expiration check: 4:34:55 ago on Wed Aug 24 09:22:24 2016.
Dependencies resolved.
==============================================================================
Package Arch
Version Repository Size
==============================================================================
Installing:
hexedit x86_64
1.2.13-8.fc24 fedora 44 k
[snap - deleted unimportant logs]
Installed:
hexedit.x86_64
1.2.13-8.fc24
Complete!
[root@localhost tools]$ which hexedit
/usr/bin/hexedit

Thank you again,
Zoran

<p>I'm a bit confused as to where you are coming from with this -
you can search for ASCII/hex strings using something as light as
hexedit. No need to install a more full-blown hex editor

From the pointer:<b> <i><u>magic</u></i></b><i><u> is a

Interesting enough, wxHexAuthor Erdem (U. Altinyurt) is a
jobless computer engineer, born and living since 1981,in
Istanbul, Turkey. Why Erdem is jobless, that is the (crucial)
question??? ;-)<br>

I would like to know if it is possible, via a
