Is chmod 302 Safe?

- Scripts need read permission to run; only compiled binaries can be executed without it.
- Unusual: a lower class has permissions the class above it lacks.
Common Use Cases
302 is uncommon in standard Linux setups. The closest widely used permission is chmod 700.
chmod 302 Command Examples
# Apply using octal mode
chmod 302 filename
# Apply using equivalent symbolic mode
chmod u=wx,g=,o=w filename
# Recursive command warning:
chmod -R 302 /path/to/dir
# Note: -R applies the same mode to files and directories. Use find to treat them separately:
find /path/to/dir -type d -exec chmod 302 {} +
# Verify permissions
stat -c '%a %A %n' filename # Linux
stat -f '%Lp %Sp %N' filename # macOS
