How to encrypt all data in a folder recursively?

Question

I can use:

for f in .* ; do [ -f $f ] && openssl aes-256-cbc -in $f -out $f -k PASSWORD ; done

to encrypt all hidden files in a folder and use:

for f in * ; do [ -f $f ] && openssl aes-256-cbc -in $f -out $f -k PASSWORD ; done

to encrypt all visible files in a folder. Is it possible to combine these two commands? And are there other potential types of files that are not matched by * and .*?

Does this answer your question? Best way run a command on each file in a directory tree — muru, Mar 25 '20 at 03:12
* isn't recursive. You'd need something like bash's globstar (**). Or just use find. — muru, Mar 25 '20 at 03:14
@muru can you write an answer using find? I also realized it isn't recursive but I am not sure how to use find with openssl particularly I don't know how to get $f from the original command. — Aero Wang, Mar 25 '20 at 07:33
find . -type f -exec openssl aes-256-cbc -in {} -out {} -k PASSWORD \; I'd expect. Though I am not certain writing to the same file works well with openssl. I think it truncates the output file immediately, so it will read from an empty file. — muru, Mar 25 '20 at 08:49
Double-quote those variables when you use them ("$f" instead of $f) — Chris Davies, Mar 26 '20 at 17:55

I use the && thing:

for f in .* ; do [ -f $f ] && openssl aes-256-cbc -in $f -out $f -k PASSWORD ; done && for f in * ; do [ -f $f ] && openssl aes-256-cbc -in $f -out $f -k PASSWORD ; done

Ex. echo 1 && echo 2 returns

This doesn’t do anything that couldn’t be done more simply by for f in .* * ; do …. More importantly, this doesn’t work recursively. – Scott - Слава Україні Sep 24 '20 at 23:49
Also -- if there is an error in one command, the next ones won't be executed. – Alex Sep 25 '20 at 05:18
