Hexdump oneliner

php -r 'for(;$r=fread(STDIN,16);)printf("%08x %s $r\n",$i++*16,join(unpack("h*",$r)));'

Found it on hexdump.io

An internal application is distributed as "bunch files without extensions". To figure out what types of files they are I need to hexdump each one, look for the identifiers, and then add the extensions…

Who distributes anything without extensions and why? Also how is a non-programmer expected to figure this out? (tool's audience is mainly EPMs)

i want to find the person who proposed to force mtp in android for file transfers, and bash them in the head with a plush android toy till they're knocked unconscious.

all i want is to make a file transfer between my phone and my computer, and rather than plugging my phone's usb, i find it easier to set up an ftp server over local network. and when that doesn't work, i might as well hexdump the file, and copy it char-by-char manually, than use mtp.
