0o5522

0o5522 is an octal notation used in computing to represent a specific numeric value. The prefix 0o indicates octal (base-8) in several programming languages, such as Python, and is also used in Unix-like systems to denote permission modes.

In decimal, 0o5522 equals 2898. Its hexadecimal representation is 0xB52. As an octal value, each digit maps to particular bits when used as a permission mode in Unix-like systems, with the first digit representing special bits and the remaining digits representing user, group, and other permissions.

As a Unix file mode, 0o5522 can be interpreted as a four-digit octal permission. The first digit (5) indicates special bits are set (for example, setuid and sticky bits in this case). The next digits define the standard permission bits: the owner has read and execute permissions (5), the group has write permission only (2), and others have write permission only (2). In practice, this combination affects how a file can be executed or modified, and the sticky bit is primarily meaningful for directories, while setuid has implications when executing programs. The exact symbolic representation depends on the system and the file type, and some bits may be ignored in certain contexts.

Beyond permissions, 0o5522 appears primarily as a numeric literal in programming and as a mode specification in shell commands like chmod 5522 file, where the digits translate directly to the corresponding special, user, group, and other bit settings.
