0o4661

0o4661 is an octal numeral written with the 0o prefix, a convention used by several programming languages (notably Python) to denote a base-8 integer literal. In decimal form, 0o4661 equals 2481, since 4×512 + 6×64 + 6×8 + 1×1 = 2481.

The digits in 0o4661 can be read as a combination of special bits and ordinary base-8 permission bits. The first digit, 4, indicates that the setuid flag is set in contexts that interpret the number as a Unix-style file mode. The next digits (6, 6, 1) correspond to owner, group, and other permissions, respectively: 6 means read and write permission (no execute) for both the owner and the group, while 1 means execute permission for others.

In Unix-like environments, a four-digit octal value like 04661 can be used to specify file permissions and special flags via commands such as chmod. Interpreting 04661 as a file mode yields a configuration where setuid is enabled, the owner and group have read and write access, and others have execute access. The exact textual representation (for example, how it appears in a long directory listing) depends on the presence of the owner execute bit, because the setuid flag interacts with the execute bit in the displayed permissions.

Contextual usage of 0o4661 varies by domain. In programming, it serves as a concrete octal value for calculations, bitwise operations, or data represented in base-8 form. In systems administration, interpreting it as a file mode carries implications for security and access control, given the presence of the setuid flag and mixed permission bits.
