chmod 514 Command Examples

# Apply using octal mode
chmod 514 filename

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

# Recursive command warning:
chmod -R 514 /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 514 {} +

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

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