Common choices
- 644 for normal files (only the owner can change them).
- 755 for folders and scripts.
- 600 for private files such as SSH keys and .env files, and 700 for private folders.
- Avoid 777: everyone on the server can change the file.
Veelgestelde vragen
What do s and t mean in rwsr-xr-x?
s is setuid or setgid: the program runs with the owner's (or group's) rights. t is the sticky bit: in a shared folder, people can delete only their own files. A capital S or T means the bit is set without execute permission.
