Best I can do is

"\ude41🙂".split("").reverse().join("")

returns "\ude42🙁"

Oof yeah, some programs really love to touch a lot of stuff making strace kind of annoying to use. I usually end up chaining more grep -v pipes on the end as I find files I’m not interested in seeing e.g.

strace okular | grep openat | grep -v breeze-dark | grep -v icon

Might help to first save it to a file so you don’t have to keep relaunching okular as you add more inverse greps

strace okular | tee some-file
^C
cat some-file | grep -v ...

I would probably try running

strace okular | grep openat

to see all the files it’s trying to read and see if any aren’t managed by your package manager and move those.

But the latest reply by felixernst in the kde discuss also looks helpful.

On my machine at least man openssl shows that -k is for specifying the password you want to derive the key from, so in that case I think you are literally using the string /etc/ssl/private/etcBackup.key as the password. I think the flag you want is -kfile.

You can verify this by running the command in strace and seeing that there is no openat call for the file passed to -k.

Edit: metiulekm@sh.itjust.works beat me to it while I was writing out my answer :)

While I agree that first party systems suck, as someone with neither an iOS or Android device I personally prefer something work rather than a screen that says “connect iOS/Android”.
