Not sure I understand this. Why do you need a “new” file?
If the file already exists, you are not creating a new file and the existing file permissions will remain?
The recommended chmod command is in the standard install instructions (though that’s on the directory).
If I understand this correctly:
chmod 700on the directory means only you (the owner) can enter/read/list/write in that directory or see its contents.- Even if a file is world-readable (e.g.
chmod 644), nobody else can access it because they can’t get into the directory in the first place.
btw, are you able to take screen snippets or even better just copy the text? Your camera photos will be less accessible to search etc.
