Is chmod 350 Safe?

Low Risk

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

350 is uncommon in standard Linux setups. The closest widely used permission is chmod 750.

chmod 350 Command Examples

# Apply using octal mode
chmod 350 filename

# Apply using equivalent symbolic mode
chmod u=wx,g=rx,o= filename

# Recursive command warning:
chmod -R 350 /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 350 {} +

# Verify permissions
stat -c '%a %A %n' filename    # Linux
stat -f '%Lp %Sp %N' filename   # macOS

# Example ls -l output:
--wxr-x--- 1 alice staff 1024 Jan 15 10:00 example.txt
