Hmm,
Tried chatgpt now and it says this should work:
if ! cat "$1/$file" 2>/dev/null; then
printf "$file is not readable\n"
fi
- This attempts to read the file.
- If it fails, the cat command returns non-zero, and you print a message.
- 2>/dev/null suppresses error messages (Permission denied, etc.)
- This works reliably for both root and non-root users, because it actually
tests the read action, not just permission bits.
