Using "grep" command to find Crypto Seed Phrase - awk

Question

Let’s say I have my 24 word crypto backup phrase somewhere on my PC and I don’t know where. it’s a total of 2048 words or so.
How can I use grep to print all/any files containing at least 2 words in given string? I found how to print with?
grep 'extra|value' but that’s for 2 words and they both must be found. how found I grep or whatever command to find any file containing at least 2 words from given string of 2048 words. thanks!
grep 'extra|value'

Answer 1

You cannot use a single grep run to find two different words potentially on different lines. But you can first list all the files containing one word and then search only those for the second one:
find / -type f -exec grep -l 'extra' {} + | xargs grep 'value'

Answer 2

2 words and they both must be found
I would harness GNU grep for this task following way
grep --perl-regexp --recursive --null-data '(extra[.\n]*value)|(value[.\n]*extra)' .
Explanation: I start search from current directory (.) and traverse all subdirs (--recursive) looking for files which have (extra followed by zero-or-more any characters followed by value) OR (value followed by zero-or-more any characters followed by extra. I use --perl-regexp combined with --null-data combined with \n to allow words being in different lines. Consult grep man page if you need further explanation of options used.

Answer 3

Use find + awk
find / -type f -exec awk 'FNR==1{a=b=0} /extra/{a=1} /value/{b=1} a&&b{print FILENAME; nextfile}' {} +`
That requires an awk that has nextfile which most do these days. If yours doesn't then pipe the output to sort -u or uniq to ensure unique file names.

Answer 4

From man grep (GNU grep and BSD grep)
-E, --extended-regexp
Interpret PATTERNS as extended regular expressions (EREs,
see below).
...
grep understands three different versions of regular expression
syntax: “basic” (BRE), “extended” (ERE) ...
That includes the use of logical "or" | in the search pattern.
-n: print line numbers (somewhat guarantees : as record sep)
-o: only print matches (more than one hit on same line)
-H: print matching files names
The awk prints matched files with more than 1 hit.
% str="labore|dolor"
% grep -EnoH "${str}" {file,file2} |
awk -F ':' 'NF>1{x = $1} {mat[x,$NF]++}
END{for(i in mat){split(i, arr, SUBSEP); a[arr[1]]++};
for(i in a){if(a[i] > 1){print i}}}'
file
include -w to only match whole words.
