hello,
I doing some code in perl and I'm not very good at it.
code makes some images and saves them to a directory.
If the directory doesn't exist it gets made and if it does exist all
the
files in it get deleted before putting some new ones in.
I'm thinking that if I ever give it to somebody it's possible they
might
call the directory
"~/" or something and end up deleting all their files, which I'd like
to
avoid.
How would that best be avoided ?
Is that something to do with chroot which I don't know anything
about.
always put things in a subdirectory.
there is normally a directory named .local/share/<program-name>/
used for such things (or create it if it isn't there).
if you have any configuration information that can be saved in
the .config/<program-name>/ directory (or again create it if it
isn't there).

Ah Ok, I could assert a directory and then the output directory make
that a subdirectory.
so if they typed "~/"
"./images_out/~/" would cause an error ?
