comment Copying latest modified file from multiple directories
Do you mean the single most recently-modified file, however many directories there are? Or if there are 7 directories, do you want to copy 7 files (the most recently modified from each)?

comment Is `~/Documents` a relative or an absolute path?
You can find it dubious all you want, but it's documented and should be easy to confirm or disprove in C.

Not on Linux at least (you can see that glibc:fgetpwent grows its buffer as required). The GECOS field is an addition to the POSIX standard, so you'd need to check any other platforms individually.

For OP's reference: the $variable part is Shell Parameter Expansion, and the > part is Redirection

Surely that's (127-32)^32, not (127-32)*32?

Oh and @Fiximan - you'll need to post that as an answer to collect the sweet kudos.

comment How do I take a prompt response and send it to a text file?
Start by looking at existing shell scripts, either online or various system scripts under /etc/ or wherever. You won't understand all of them, but can look up the syntax you don't recognise in man bash or online, and ask a question if you can't find the answer yourself. Similarly, commands you don't recognise will probably have their own man pages.

comment Sources of Entropy for Linux
It mentions a one-time pad as one of two exceptions to the assertion that _'... almost all of the cryptographic algorithms ... “only” offer computational security'. Unless you can quote something I missed where it says one-time pads can't use urandom?

What exactly makes you so sure that /dev/urandom isn't strong enough for your purpose?

comment What is spinning my disk up periodically?
FYI, you may be able to avoid this sort of wakeup if you can safely send these transient writes to a tmpfs mount.
