Top Forums Shell Programming and Scripting When comparing binary files, show human readable result? Post 303043371 by RudiC on Sunday 26th of January 2020 02:34:01 PM

How about
Code:
cmp -bl file[12] | awk '{LSTR = LSTR $3; RSTR = RSTR $5} END {print "left: ", LSTR; print "right:", RSTR}'
left:  69360bac2b3b7af4a4a67f6962
right: e1ccb4ce590a49a5905c05dc86

Unfortunately, this does not display the hyphens as they are identical in both files.


EDIT: alternatively, try

Code:
diff <(strings file1) <(strings file2)
12c12
< *69a3604b-ac2b-43b7-af84-0a4a67fc6962
---
> *e1accb44-ce59-40a4-9a85-0905c05cdc86

this might suffer if UTF-8 chars greater than 127 are close / around the strings of interest...


EDIT: or


Code:
cmp -bl file[12] | awk 'NR == 1 {OUT = sprintf ("xxd -pc1 -s%d ", X = $1 - 1)} END {OUT = OUT sprintf ("-l%d file", $1 - X); print OUT "1"; print "printf \"0A\n\""; print OUT "2"; print "printf \"0A\n\""}' | sh | xxd -p -r
69a3604b-ac2b-43b7-af84-0a4a67fc6962

irsend - basic LIRC program to send infra-red commands SYNOPSIS
irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
