Hello Riko,

I recently also became very interested to start using radare2 (Raphael
Machado's dissasembly attempts got involved me, to set the tool). Since I
am very lazy person, the first was to ask my Fedora 25 distro does the
distro have package radare2?

Yes, it does have it, so I have installed it. And for you, here is the
transcript of my CLI for you.

CLI traces (radare --help) are worth 1000nd words, don't you agree? ;-)

Best Regards,

[zoran at localhost ~]$ uname -r
[zoran at localhost ~]$ which radare2
*[zoran at localhost ~]$ radare2 --help*

 -o [OS/kern] set asm.os (linux, macos, w32, netbsd, ...)
 -q           quiet mode (no prompt) and quit after -i
 -p [prj]     use project, list if no arg, load if no file
 -P [file]    apply rapatch file and quit
 -R [rarun2]  specify rarun2 profile to load (same as -e dbg.profile=X)
