TLS doesn’t encrypt the host name of the urls you are visiting and DNS traffic is insanely easy to sniff even if you aren’t using your ISPs service.

the hostname of a website is explicitly not encrypted when using TLS. the Encrypted Client Hello extension fixes this but requires DNS over HTTPS and is still relatively new.

SMS is literally the bottom of the barrel though

assuming you have a GNU toolchain you can use the find command like so:

find . -type f -executable -exec sh -c '
case $( file "$1" ) in (*Bourne-Again*) exit 0; esac
exit 1' sh {} \; -print0 | xargs -0 -I{} cp {} target/

This first finds all executable files in the current directory (change the “.” arg in find to search other dirs), uses the file command to test if it’s a bash file, and if it is, pipes the file name to xargs which calls cp on each file.

note: if “target” is inside the search directory you’ll get output from cp that it skipped copying identical files. this is because find will find them a free you copy them so be careful!

note 2: this doesn’t preserve the directory structure of the files, so if your scripts are nested and might have duplicate names, you’ll get errors.

why use docker here? you’re just adding layers of abstraction in an environment that can’t seem to really support them.

that said, switching to 32bit linux, if the VPS supports it, will save you memory.
