Find revelation files

[ANIS El Achèche]

Hi!

How can I use the find command to find all the revelation files in my Linux Box?

Combining find with the file command don't give a good result as the revelation files mime type is "application/octet-stream" and it's not a unique mime-type.

Thank you in advance

You can try this:
find . -type f | while read -r line; do head -c 6 "$line" | xxd -p && echo "$line"; done | grep -A 1 72766c

The following explains and amends Kislin's "one liner" to produce just a list of file names, stripping the revelation password file signature from the output.

#!/bin/sh

# Combining *find* with the *file* command don't give a good result as the
# revelation files mime type is "application/octet-stream" and it's not a
# unique mime-type.

# How can I use the linux 'find' command to show all revelation password files?

# find . -type f | while read -r line; do head -c 6 "$line" | xxd -p && echo "$line"; done | grep -A 1 72766c

# explanation
#-------------
# 'find' selects each regular file in the current working
#  directory (and its subdirectories), printing its name.
# for each filename
#    'head' extracts the 1st 6 bytes from that file
#    'xxd' converts them to hexdump format,
#    'printf' prefixes the dumped signature to the
#     filename from 'find', separated by a blank
# 'grep' only passes on lines that begin with '72766c',
#   the signature for revelation password files
# 'cut' strips the signature, leaving only the
#   filename from 'find'

# Clearly, this sequence can be generalized for other
# types of data files by supplying a signature as a
# parameter.

# pretty-print as multi-line
# add parameter for signature
# all params in CAPS
# collapse to one line per file found and
# replace 'echo' with 'printf'

SIG='72766c'
